Thank you very much. It's very difficult connecting amps and speakers with someone who has never worked with sound system gear who thinks they know it all. This video, if he pays attention and doesn't get me all mixed up, will show him what I've been trying to tell him all along. I had never worked with speakon cabling before and that is what we have now and you have taught me a tremendous, invaluable amount of knowledge concerning the use of these cables. This has probably cost my friend, I know it all, tons of money. He has blown amps, speakers, tweeters...and the list goes on. Especially if I still can't get him to listen to you, me or anybody. Thanks again.
@@GLBProductions LOL. He owns half the gear and he's my brother in law. But u r rite. Live gigs we usually try to hire an outside person and throw it all on them. No, I end up being the guy who has to hook everything up while he barks and complains. Last time, I threw all that on him and he freaked out. I just ran in and fixed things real quick. IN and OUT.

I have talk to ingeniers that seen to be friendly and wen it comes to asking a simple question they shut down and offer you "help" by a exchange of money. Thank you for sharing your knowledge I know it may cost you a lot to learn but sharing is priceless.
Glb, i love your videos, but im to dumb to understand it all. I have two satelite speakers (passive)at 120watt and 8 ohm, and one subwoofer 200watt 8ohm (passive) all with just normal wire, so no rca jacks. Can you pleas give a few examples of amplifiers i can use? Thank you
Thanks for this very comprehensive guide on the bridging of the amp for one subwoofer. I almost threw away my 500w per channel power amp when I got a 800w subwoofer.
Jacob Falk It depends on the amplifier, but I personally have never seen an amplifier with a 1/4" bridge mono output. On amps of that generation the bridged output was always on binding posts.

thanks this was great video, I did not understand all this for the last 20 years but from watching this I now know and can be positive of what I am doing. Thanks a lot!
Sir I thank you for your video lessons here . I am a novice in what your sharing . I simply know basic knowledge on setting up my own active and passive speakers each having their own system . What I want to learn is how to combine both active and non active speakers or is this advisable otherwise I wouldn't anymore think about this . I am not really a pro DJ or soundguy and just do this as a hobby and when my friends would ask me from time to time for all of us to have fun . I learn better visually so I will be. Dry to see you doing a demo on this subject if you don't mind . You really take time explaining and showing everything in such a way your style is not. Why confusing to watch and listen too. Thank you.
Splendidly clear explanations without pointless repetitions or not needed information to confuse people with less knowledge. Was just trying to find some insight into bridging with speakon cables. I found out my amplifiers use the one where you need to reroute the wires, so will be using an adapter in the end of the cables when I need to bridge the amplifiers for larger setups. Subbed and hope to see more great videos like this in the future.
Thanks for watching! Another method for amps that are permanently rack mounted is to bring the amp outputs out to panel mount speakon connectors - you would have one each for channels A and B, and one more for bridge mode, wired to the binding post outputs.

@@GLBProductions I honestly had no clue that bridge mono was a little more complicated. If not for your video, there's a good chance I'd have unknowingly blown up some equipment. I'm a bassist who's using power amps to give me my stage volume.
Oh yes, this is one area where you really do need to know what you doing... mind you, modern power amps are generally very good at protecting themselves from all manner of human error, including dead shorts in the output wiring 😱
Thank you. Searched for 30min trying to find ANY videos on passive speakers much less how to setup properly. Thanks again. Only complaint, with my ADD mind there were few times I drifted away. [no offense but I felt like I was back in high school 20+yrs ago, listening to boring history stuff but had to fight my ADD and keep focus cuz if I don’t I’ll fail the class and have to repeat the grade all over again. 😂] ( maybe throw some jokes in smile a bit in your voice. Seem a bit happier) but other then that 1 small constructive criticisms, it was very helpful. THANK YOU👍🏻👍🏻👍🏻👍🏻🤡😉🙃😁
You're welcome! That amp has a dedicated bridge mono output that uses the standard +1/-1 speakon pin assignment so you can hook up with standard cables.
Finally someone who knows how to use language to inform others without um,ah double ahhhh .In Bridge mode can you have more than 1 speaker connected ??? Thanks
Hi, I'm from Philippines. Your videos are very helpful. Thank you for sharing with us. Just have a question because I'm planning to buy a subwoofer speaker that is 18inch 7000W. Is it okay to use this CLASS H Professional Power Amplifier which have the specs below? 1700W 8ohms stereo power 3000W 4ohms stereo power 5000W 8ohms bridge power 20Hz-20KHz, (+0/ -0.5dB) Freq. Response 300-400 Damping Factor >105dB S/N Ratio >82dB Crosstalk; 45/ s Slew Ratio 0dB (0.775V), 1V, 1V, 1.4V (changeable) Input sensitivity If its okay, how many 7000W speaker can I use when connecting into bridge mode?
Yes you talk in words almost everyone can understand,can you use amps like these to use in home theater like I have an av receiver but I want more power?
My Friend thanks alot for your wonderful video. Very clear the audio and video its self. i hope you post more video like this so you can teach alot more thanks and GOD Bless you my friend.
this teacher is very clear.One question I want to ask is what is a Rotel linkcable.I bought a Rotel RC-1572 pre-amp.The pre-amp is powered on but no signals in either input stage.
No I have not. That amplifier has no physical switch to activate bridge mono mode - the switching is done from within the menu system, as outlined in the user manual.
I recently used a yorkville px1700 and the sound went out mid way during a show. There is power and I see the meters moving but no sound is being sent to the speakers. I switched out to an older amp and the sound came back on so it’s not the wiring or blown speakers any ideas? Do these amps have internal fuses? I’m looking for some help thanks and I appreciate the videos! 😎
If you see the meters on the amp moving but no sound is coming out of the speakers that suggests the amp is in protection mode - did it resume working after the show?
@@GLBProductions yes it turned on the other day. It was very strange. I have 4-8ohm subs and daisy chained them all to get it down to 2ohms. It must of overloaded I was only using half the power amp. Is there a way to use both A&B channels. I’m so confused but any help or direction would be greatly appreciated.
Yes, you can use the 'mono' mode (actually parallel mono) to send the signal from the channel A input connector to both channels without any additional cables. Re-arrange your subs so that the load on each channel is 4 ohms and then run some tests to see if the amp shuts down again. If the 'protect' light on the front panel comes on this means that there is some issue with your speakers or speaker wiring. Finally, remember that the cooling path on this amp is front to back - check to see that both the front and back of your amp rack are unobstructed (the hot air needs somewhere to go) and do not mix with amplifiers that have a back to front cooling path. If the amp shuts down again then you should probably contact Yorkville tech support. All the best 😄
FIRST!.. i was waiting for this video.. Thanks Bruno for explaining how to do Bridge mode.. i had a sense of how to but you made it really clear and you explain it so that i feel comfortable in doing Bridge mode on my QSC PLX3402.. Thanks a lot!!
Great explanation, thanks.I want more volume from Behringer PMP4000 pa, min bridge impedance is 8 ohm. I have 2 x 8ohm speakers can I connect them in series to give 16 ohm and to do this would I have to alter the internal wiring of the speakers?
You're welcome Jon. Yes you would need to alter the internal wiring of the speakers - series wiring is not recommended for live sound as a fault in either speaker would silence your entire system.
Hi I watch your video however it didn't cover my issue. I'm trying to figure out whether to use one RCA input to the bridged car amplifier or with a y adapter used both left and right. the manual has the speaker wiring as left positive and right negative for positive and negative speaker connections respectively. The owners manual does not state whether to use one or both with a y adapter. What do you think sir? I have another brand amp from the same year that states in the manual specifically to use the left only, the speaker wiring in the bridged mode is the same as the one listed above and also has a switch for bridged or stereo mode, not that that makes any difference. Thank you
This video is directed at users of pro-audio power amplifiers such as the one shown in the video. I'm not familiar with car amplifiers and don't give advice on them - I recommend you contact the amp manufacturer and ask them these questions.
Thanks for the info, now I'm totally confused. I have a Crown XLS 602 poweramp and I want to connect it to my Rockville RSG15 15 3-Way 1500 Watt 8-Ohm Passive DJ/Pro Audio PA Speaker. How do I connect then to get the best performance from the speakers and protect the amp at the same time?
Right, so the first thing is you have to know your numbers: What is the output of your amplifier when run bridged into 8 ohms, and what is the program rated power handling of your loudspeaker?
Thanks Bruno for your educative videos. I have a problem with my 2800 watts wharfedele pro amplifier each time I use the bridge mode, it's burns my speakers. Pleases I need your help. Thanks.
Absolutely amazing videos! Very informative and to the point. Thank you for making them and please keep them coming! If you're taking requests, I'd love to see a video about connecting a powered sub. Thanks!
+drbumface You're very welcome, thanks for watching and supporting the channel. Yes I have a video on connecting powered subs in the works. Stay tuned!
Another great video. Thanks so much for sharing.. Your explanations are always so clear & informative. You have a calm soothing way about you that makes it a joy to view, learn & listen too. Thanks again. :)
Very good video. But I still have a pair of doubts. In a bridge mode connection, what about the distorion (THD and IMD)? The THS+IMD is twice than in single mode? And what about the damping factor? the damping get worst or improve? I have a crossover (Behringer) with a subwoofer MONO balanced output (XLR connector). Is perfectly for supplying a MONO amplifier, but I have a stereo one. Each pin of the XLR connector is 180 degrees inverted respect the other pin. I could feed the left input with one pin and the right with the other pin, putting the woofers (both are of 8 ohms) in bridge between the "hot" outputs (red connectors) ...is well if I do that? And the woofers I connect them in parallel (4 ohms) or I connect them in series (16 Ohms) ? Hope you want responding me. I am writing from Argentina. Excuse my bad English. Thank you in advance.
I suggest that you consult the company that manufactured your particular amplifier - not all amplifiers are designed to be bridged, and output characteristics may differ from model to model. Your suggested setup with your crossover will work in theory. Woofers are typically connected in parallel for live sound applications so that a failure of a single driver does not silence the whole cabinet.
Hello so you say bridging the amp allows you to connect to one large speaker, but what if you want to connect to two speakers , How then? One more question I have a pair of Westlake 10" studio monitors spearkers , if a amp doesn't have enough power to push them would they sound like they are baffling with a lot of (highs) with not enough Bass? Because I have heard these name brand speakers ( 8" ) plays, the Bass sound coming from them were (Round) and powerful.
To connect to two loudspeakers you would daisy-chain them together, so amp -> first speaker -> second speaker. I'm afraid I can't answer your second question - suggest you ask somebody who is familiar with those particular speakers.
I’d heard about bridging before, but the technicalities I never understood, until. THIS VIDEO. LOVE YOUR FORMAT-- direct, simple, serious,, with just enough humor to keep it interesting. (“You have been warned”) Thank You! Now, can a multizone amplifier be bridged in the same way ?
Thanks for watching! Multizone amplifiers designed for paging and background music are typically not designed to be bridged - consult the owner's manual.
Thank you so much. Very useful info ! I just hooked my new power amp in mono bridge very good ! Yet I dont know how to hook up my subwoofer. the cable has a speakon cable terminal in the subw side and three bare wires red black and yellow in the amp side. when using only the integrated amp i hooked it up...red to + R out, blk to - L out and yellow to + L out. Could you tell me how to do it in mono bridge mode ? Sorry for my english if its not good. hope you can help me. Thanks a lot vey helpful !
GLB Productions Thank you so much for your answer. luckly I could connect them via a single ended RCA cable from the Iotavx sa3 sub out (bridged in monoblock to pa3) to the line in at Rel T5i sub. Tanks again. I really appreciate your help. Cheers👍
Hi! Maybe I'm late here. We have an amplifier at our church, the owner's manual indicates that It delivers 2,300w at 4ohm in Bridge Mode. Can I use this mode to Connect two linked speakers of 1,800w and 8ohms each? Thanks and God bless you all!
Clearest explanation ever of how bridge mode works and how to modify the connectors on Speakon cables. Thank you Sir. Question: I intent to run two 8 ohm speaker cabinets in mono bridge mode (Crown XLS 1002). After modifying the amp end of my Speakon cable per the manual - I can then "daisy chain" the second speaker cabinet to the first, and I would then be bridged into a 4 ohm load, correct?
Correct - remember that the only modification you need to make is at the amp end of the first speaker cable. The second cable joining the two cabinets together is standard wiring at both ends.
If I am using bridge mode and connecting to an older sub with only TRS / TS inputs will a TS- speakon cable work if I rewire the speakon end correctly ?
Yes it will - to use the example shown in the video you would wire tip to +1 and the sleeve to +2. Passive loudspeakers generally do not use TRS connectors.
Earlier of this informative video I was planning to buy a mono amp because I like to have only one sound box, now I can buy a stereo amp. Sir, please advise me, if have 250 +250 watts stero amp then how many watts single speaker should be connected for best result.
thank you for showing me this i had no clue tell i watched your channel now that i know how to do this i must put it to action i hope i don't disappoint u
More than 8 ohms is not a problem! With power amplifiers, higher loads like 16 ohms are fine - it just means that the amplifier delivers less power into the load.
Hi Bruno, everything worked great as you explained, now my question is this? How do you connect exterior amplifiers without bring low pass another words connecting exterior amplifiers to sub woofer preouts? I want to know? Is it possible to connect exterior amplifiers in full range?
My amp is an older model peavey which has Phone plugs. In order to send the signal from the amp (in bridge mode) I need a banana plug for the output signal and it needs to be adapted to the 1/4" phone jack for the speaker cable. My real question is there a specific way to wire the banana plug and 1/4" Phone jack - as far as ring-tip is determined. Since the Manufacturers manual say to use both red banana output jacks.
Ah ok that is definitely a custom set up: the tip of the phone plug should be wired to the channel A output and the sleeve to the channel B output. There is no ring connection when using phone plugs for speaker connections.
Hi, i hav a doubt.. can u plz clarify. Shouldn't the signal will b canceled and there will b no audio? If in bridge mode 1 channel is inverting the phase.
Not in this case because the signals are not being recombined electronically - they are fed to separate amplifier channels which are then connected to opposite polarity terminals on the same loudspeaker.
I like this video but I'm still slightly confused. I have the Behringer B215XL speakers and I want to connect them in bridge mode to a Behringer EP 2000 amp so that I can have more output power to the speakers. Can I run the speakon from 1 speaker to the amp...then using another speakon ....connect to both speakers....and then connect a parallel ¼ to 1 speaker and back to the amp.? After that set the dip switches etc for mono mode.
+Bernard Williams You don't need to connect back to the amp - the speakon carries both positive and negatives sides of the connection. So amp to first speaker and parallel out to the second speaker. This will give you 1000 watts into each speaker.
+GLB Productions Wow!!!..had no idea that I would be getting answer back so soon...figured it would be days. I think I got it.....amp to first speaker with the speakon....then parallel out to 2nd speaker from the amp.....hope I understood you correctly.....THANKS so much

Mr. B, Hope all is well You are a God send. Here's my question. I have a small Sony high fi set up the signal go to equalizer in the living room the speakers in the living room is connected to an SLA 1 amp via the binding black and red post the amp is plugged into the wall electrical out let I understand the from your video the various settings. Bridge and stereo modes, however when I turn on the units source in the bedroom then the equalizer which shows in the display there is a signal and I then turn on the amplifier there is no sound coming from the speakers What do I need to do to get them working? I set the amp in bridge mode using bare wire into the two red post one left one right as well as in stereo mode connecting the speakers to the the black and red post. As my husband who is no longer with me would have solved this issue. I hope that I say make sense as I am a neophyte to this. Blessings 🙏 Thanks in advance Pat
Hi Pat, thanks for getting in touch. There are many reasons why your system might not be working - each make and model of amplifier has its own ways of managing the signal so I can only give some general suggestions: First of all make sure that you have selected the correct INPUT on the amplifier - many hifi amps have several inputs: phono, CD, tuner etc. Also, make sure that signal is actually reaching the input of the amplifier - you mentioned an equalizer in your post above - if this is a separate component try unplugging it and running the source directly into the amplifier itself. Secondly, make sure that you have selected the correct OUTPUT - some amps have two sets of outputs, meant for two different sets of speakers. These are sometimes called A and B. Finally, it is likely that your amplifier should be run in stereo mode - bridge mono mode is usually reserved for driving subwoofers. Hope your can get your system working!
@@GLBProductionsMr. B. Thanks for responding to me. I should have also let you know that I did not use the XLR 1/4" connectors. I just attached the speaker wires in stereo mode. Should these connectors be plugged into channel one and channel two on the amp and into the equalizer.
The equalizer needs to be connected to the amplifier for sure, either via the XLR or 1/4" connectors. Left output of the EQ to channel 1 of the amp and right output of the EQ to channel 2.
Good Day,Sir i have a question how can i use my compressor limitter if my i have a stereo mode amplifier? I have a behringer xenyx1002fx mixer....how can i connect from my mixer to compressor limitter and to my stereo mode amplifier? Thank you Sir.
It depends on the impedance of the speakers and what the amplifier's minimum operating impedance is in bridge mode. See this video for more details: th-cam.com/video/l9L7uK7Xy0w/w-d-xo.html
Hello there 👋 I have a question : In my case, my 2 KCS 2000 speakers are splitted in 2 parts HF and LF. How do i have to connect those 4 wires if i choose your very last exemple ? Do i have to join the 2 left and right ➕ and connect them to the red Channel 1 all together? And the same for the 2 left and right ➖ in Channel 2? Please help me 😁

Splendidly clear explanations without pointless repetitions or not needed information to confuse people with less knowledge. Was just trying to find some insight into bridging with speakon cables. I found out my amplifiers use the one where you need to reroute the wires, so will be using an adapter in the end of the cables when I need to bridge the amplifiers for larger setups.
Subbed and hope to see more great videos like this in the future.
Thanks for watching! Another method for amps that are permanently rack mounted is to bring the amp outputs out to panel mount speakon connectors - you would have one each for channels A and B, and one more for bridge mode, wired to the binding post outputs.

@@GLBProductions I honestly had no clue that bridge mono was a little more complicated. If not for your video, there's a good chance I'd have unknowingly blown up some equipment. I'm a bassist who's using power amps to give me my stage volume.
Oh yes, this is one area where you really do need to know what you doing... mind you, modern power amps are generally very good at protecting themselves from all manner of human error, including dead shorts in the output wiring 😱
I have learnt so much from your tutorials... May God bless you
You're welcome, God Bless you too as we move into advent :)
Thank you. Searched for 30min trying to find ANY videos on passive speakers much less how to setup properly. Thanks again. Only complaint, with my ADD mind there were few times I drifted away. [no offense but I felt like I was back in high school 20+yrs ago, listening to boring history stuff but had to fight my ADD and keep focus cuz if I don’t I’ll fail the class and have to repeat the grade all over again. 😂] ( maybe throw some jokes in smile a bit in your voice. Seem a bit happier) but other then that 1 small constructive criticisms, it was very helpful. THANK YOU👍🏻👍🏻👍🏻👍🏻🤡😉🙃😁
Very glad the video was helpful 😄
actually insanely helpful. was so hard to get a god damn straight answer from people about mono bridge wiring for my Ampeg svt4
You're welcome! That amp has a dedicated bridge mono output that uses the standard +1/-1 speakon pin assignment so you can hook up with standard cables.
Finally someone who knows how to use language to inform others without um,ah double ahhhh .In Bridge mode can you have more than 1 speaker connected ??? Thanks
Yes you can - up to the amp's minimum allowed impedance in bridge mode. Thanks for watching!
Hi, I'm from Philippines. Your videos are very helpful. Thank you for sharing with us.
Just have a question because I'm planning to buy a subwoofer speaker that is 18inch 7000W.
Is it okay to use this CLASS H Professional Power Amplifier which have the specs below?
1700W 8ohms stereo power
3000W 4ohms stereo power
5000W 8ohms bridge power
20Hz-20KHz, (+0/ -0.5dB) Freq. Response
300-400 Damping Factor
>105dB S/N Ratio
>82dB Crosstalk; 45/ s Slew Ratio
0dB (0.775V), 1V, 1V, 1.4V (changeable) Input sensitivity
If its okay, how many 7000W speaker can I use when connecting into bridge mode?
Please watch this video it will answer you question: th-cam.com/video/l9L7uK7Xy0w/w-d-xo.html

You're welcome :)
@@GLBProductions Thank you !
this teacher is very clear.One question I want to ask is what is a Rotel linkcable.I bought a Rotel RC-1572 pre-amp.The pre-amp is powered on but no signals in either input stage.
Sorry but you'll have to ask Rotel about that.
Have you done one specifically on the crown xti series? I have a 4002 xti
No I have not. That amplifier has no physical switch to activate bridge mono mode - the switching is done from within the menu system, as outlined in the user manual.
Which of these would work better for looping? Sterio or dridge
Both would work, depending on whether you are looping in stereo or mono.
I recently used a yorkville px1700 and the sound went out mid way during a show. There is power and I see the meters moving but no sound is being sent to the speakers. I switched out to an older amp and the sound came back on so it’s not the wiring or blown speakers any ideas? Do these amps have internal fuses? I’m looking for some help thanks and I appreciate the videos! 😎
If you see the meters on the amp moving but no sound is coming out of the speakers that suggests the amp is in protection mode - did it resume working after the show?
@@GLBProductions yes it turned on the other day. It was very strange. I have 4-8ohm subs and daisy chained them all to get it down to 2ohms. It must of overloaded I was only using half the power amp. Is there a way to use both A&B channels.
I’m so confused but any help or direction would be greatly appreciated.
Yes, you can use the 'mono' mode (actually parallel mono) to send the signal from the channel A input connector to both channels without any additional cables. Re-arrange your subs so that the load on each channel is 4 ohms and then run some tests to see if the amp shuts down again. If the 'protect' light on the front panel comes on this means that there is some issue with your speakers or speaker wiring. Finally, remember that the cooling path on this amp is front to back - check to see that both the front and back of your amp rack are unobstructed (the hot air needs somewhere to go) and do not mix with amplifiers that have a back to front cooling path. If the amp shuts down again then you should probably contact Yorkville tech support. All the best 😄
FIRST!.. i was waiting for this video.. Thanks Bruno for explaining how to do Bridge mode.. i had a sense of how to but you made it really clear and you explain it so that i feel comfortable in doing Bridge mode on my QSC PLX3402.. Thanks a lot!!
+dee fresh You're welcome! Enjoy the power of bridging your amplifier! :D
Great explanation, thanks.I want more volume from Behringer PMP4000 pa, min bridge impedance is 8 ohm. I have 2 x 8ohm speakers can I connect them in series to give 16 ohm and to do this would I have to alter the internal wiring of the speakers?
You're welcome Jon. Yes you would need to alter the internal wiring of the speakers - series wiring is not recommended for live sound as a fault in either speaker would silence your entire system.
Thanks, will look for a more powerful pa

Hi I watch your video however it didn't cover my issue. I'm trying to figure out whether to use one RCA input to the bridged car amplifier or with a y adapter used both left and right. the manual has the speaker wiring as left positive and right negative for positive and negative speaker connections respectively. The owners manual does not state whether to use one or both with a y adapter. What do you think sir? I have another brand amp from the same year that states in the manual specifically to use the left only, the speaker wiring in the bridged mode is the same as the one listed above and also has a switch for bridged or stereo mode, not that that makes any difference. Thank you
This video is directed at users of pro-audio power amplifiers such as the one shown in the video. I'm not familiar with car amplifiers and don't give advice on them - I recommend you contact the amp manufacturer and ask them these questions.
Thanks for the info, now I'm totally confused. I have a Crown XLS 602 poweramp and I want to connect it to my Rockville RSG15 15 3-Way 1500 Watt 8-Ohm Passive DJ/Pro Audio PA Speaker. How do I connect then to get the best performance from the speakers and protect the amp at the same time?
Right, so the first thing is you have to know your numbers: What is the output of your amplifier when run bridged into 8 ohms, and what is the program rated power handling of your loudspeaker?
Thanks Bruno for your educative videos. I have a problem with my 2800 watts wharfedele pro amplifier each time I use the bridge mode, it's burns my speakers. Pleases I need your help. Thanks.
+Isaac ohaeri Have you checked that your amp and speakers are correctly matched?

You're welcome, God Bless you too!
Very good video. But I still have a pair of doubts.
In a bridge mode connection, what about the distorion (THD and IMD)?
The THS+IMD is twice than in single mode?
And what about the damping factor? the damping get worst or improve?
I have a crossover (Behringer) with a subwoofer MONO balanced output (XLR connector). Is perfectly for supplying a MONO amplifier, but I have a stereo one. Each pin of the XLR connector is 180 degrees inverted respect the other pin. I could feed the left input with one pin and the right with the other pin, putting the woofers (both are of 8 ohms) in bridge between the "hot" outputs (red connectors) ...is well if I do that? And the woofers I connect them in parallel (4 ohms) or I connect them in series (16 Ohms) ?
Hope you want responding me.
I am writing from Argentina. Excuse my bad English.
Thank you in advance.
I suggest that you consult the company that manufactured your particular amplifier - not all amplifiers are designed to be bridged, and output characteristics may differ from model to model.
Your suggested setup with your crossover will work in theory.
Woofers are typically connected in parallel for live sound applications so that a failure of a single driver does not silence the whole cabinet.
Hello so you say bridging the amp allows you to connect to one large speaker, but what if you want to connect to two speakers , How then? One more question I have a pair of Westlake 10" studio monitors spearkers , if a amp doesn't have enough power to push them would they sound like they are baffling with a lot of (highs) with not enough Bass? Because I have heard these name brand speakers ( 8" ) plays, the Bass sound coming from them were (Round) and powerful.
To connect to two loudspeakers you would daisy-chain them together, so amp -> first speaker -> second speaker. I'm afraid I can't answer your second question - suggest you ask somebody who is familiar with those particular speakers.
@@GLBProductions Thanks
Thank you for sharing your experiences. Watching all the way from Vanuatu 😀😁👍🔥🔥🇻🇺🇻🇺🇻🇺

Can you explain EMX 2000 power mixer to connect to amplifier please
On that mixer use the +4dB line level outputs on the top panel to connect to a power amp.
I’d heard about bridging before, but the technicalities I never understood, until. THIS VIDEO. LOVE YOUR FORMAT-- direct, simple, serious,, with just enough humor to keep it interesting. (“You have been warned”) Thank You!
Now, can a multizone amplifier be bridged in the same way ?
Thanks for watching! Multizone amplifiers designed for paging and background music are typically not designed to be bridged - consult the owner's manual.
Thank you for making clear things on the amplifier

Thank you so much. Very useful info ! I just hooked my new power amp in mono bridge very good !
Yet I dont know how to hook up my subwoofer.
the cable has a speakon cable terminal in the subw side and three bare wires red black and yellow in the amp side.
when using only the integrated amp i hooked it up...red to + R out, blk to - L out and yellow to + L out.
Could you tell me how to do it in mono bridge mode ?
Sorry for my english if its not good. hope you can help me.
Thanks a lot vey helpful !
Which make and model is your integrated amplifier please?
GLB Productions Thank you so much for your answer.
luckly I could connect them via a single ended RCA cable from the Iotavx sa3 sub out (bridged in monoblock to pa3) to the line in at Rel T5i sub. Tanks again.
I really appreciate your help.
Cheers👍
Hi! Maybe I'm late here. We have an amplifier at our church, the owner's manual indicates that It delivers 2,300w at 4ohm in Bridge Mode. Can I use this mode to Connect two linked speakers of 1,800w and 8ohms each? Thanks and God bless you all!
Yes you can - each loudspeaker will receive 1150 watts.
@@GLBProductions great! Thanks for your help man. God bless you!
Clearest explanation ever of how bridge mode works and how to modify the connectors on Speakon cables. Thank you Sir. Question: I intent to run two 8 ohm speaker cabinets in mono bridge mode (Crown XLS 1002). After modifying the amp end of my Speakon cable per the manual - I can then "daisy chain" the second speaker cabinet to the first, and I would then be bridged into a 4 ohm load, correct?
Correct - remember that the only modification you need to make is at the amp end of the first speaker cable. The second cable joining the two cabinets together is standard wiring at both ends.
Precise and straight to the point..... God bless you
Thanks for watching!
If I am using bridge mode and connecting to an older sub with only TRS / TS inputs will a TS- speakon cable work if I rewire the speakon end correctly ?
Yes it will - to use the example shown in the video you would wire tip to +1 and the sleeve to +2. Passive loudspeakers generally do not use TRS connectors.
Earlier of this informative video I was planning to buy a mono amp because I
like to have only one sound box, now I can buy a stereo amp.
Sir, please advise me, if have 250 +250 watts stero amp then how many watts single speaker should be connected for best result.

Hi Bruno. When using an amp in bridged mono, can you also use it in another mode
No, you can only select one mode at a time. More info here: th-cam.com/video/HKpV30pjvIo/w-d-xo.html
@@GLBProductions thanks Bruno
Hi sir, what if bridge mode more than 8ohms what happen to the amplifier i thank you from the philippines.
More than 8 ohms is not a problem! With power amplifiers, higher loads like 16 ohms are fine - it just means that the amplifier delivers less power into the load.
Very clear explanation from you.thank u very much.
You're welcome Sapumal.
Hi Bruno, everything worked great as you explained, now my question is this? How do you connect exterior amplifiers without bring low pass another words connecting exterior amplifiers to sub woofer preouts? I want to know? Is it possible to connect exterior amplifiers in full range?
I have a pioneer sclx501 receiver!
I suggest using the line out connectors to connect to external amplifiers as these will be fullrange with no low pass filter.
I tried the pre/ line out before and it was blasting with no volume control, unless I hooked it up wrong??
No that's correct, you have to control the volume using your external amplifier.
Holy damn!! thank you for going into detail on each and every thing, step by step. Thank you again this explained it perfectly to me.
You're welcome!
Hi Bruno could you show the connection on the speakon that is the +2 -2 bridge mode connection
+Gbenga Ojo The way to do this is shown in the video at around 13:07.
Bruno, do have a video on making an adapter cable for bridge mode in a 1/4" phono set-up?
No I do not, in fact I don't even know what that is :) What are you trying to achieve?
My amp is an older model peavey which has Phone plugs. In order to send the signal from the amp (in bridge mode) I need a banana plug for the output signal and it needs to be adapted to the 1/4" phone jack for the speaker cable. My real question is there a specific way to wire the banana plug and 1/4" Phone jack - as far as ring-tip is determined. Since the Manufacturers manual say to use both red banana output jacks.
Ah ok that is definitely a custom set up: the tip of the phone plug should be wired to the channel A output and the sleeve to the channel B output. There is no ring connection when using phone plugs for speaker connections.
Thanks Bruno. I had concern about it being wired in a specific way. You may have said this in your video and I just kept missing it, SORRY!
Hi, i hav a doubt.. can u plz clarify.
Shouldn't the signal will b canceled and there will b no audio?
If in bridge mode 1 channel is inverting the phase.
Not in this case because the signals are not being recombined electronically - they are fed to separate amplifier channels which are then connected to opposite polarity terminals on the same loudspeaker.
awesome... i already got the point what its means by the mode between stereo, parallel and bridge, thanks a lot for the clarify Mr. Bruno
+ceejay music You're welcome, thanks for watching!
I like this video but I'm still slightly confused. I have the Behringer B215XL speakers and I want to connect them in bridge mode to a Behringer EP 2000 amp so that I can have more output power to the speakers. Can I run the speakon from 1 speaker to the amp...then using another speakon ....connect to both speakers....and then connect a parallel ¼ to 1 speaker and back to the amp.? After that set the dip switches etc for mono mode.
+Bernard Williams You don't need to connect back to the amp - the speakon carries both positive and negatives sides of the connection. So amp to first speaker and parallel out to the second speaker. This will give you 1000 watts into each speaker.
+GLB Productions
Wow!!!..had no idea that I would be getting answer back so soon...figured it would be days. I think I got it.....amp to first speaker with the speakon....then parallel out to 2nd speaker from the amp.....hope I understood you correctly.....THANKS so much

Here's my question. I have a small Sony high fi set up the signal go to equalizer in the living room the speakers in the living room is connected to an SLA 1 amp via the binding black and red post the amp is plugged into the wall electrical out let
I understand the from your video the various settings. Bridge and stereo modes, however when I turn on the units source in the bedroom then the equalizer which shows in the display there is a signal and I then turn on the amplifier there is no sound coming from the speakers
What do I need to do to get them working? I set the amp in bridge mode using bare wire into the two red post one left one right as well as in stereo mode connecting the speakers to the the black and red post. As my husband who is no longer with me would have solved this issue. I hope that I say make sense as I am a neophyte to this.
Blessings 🙏
Thanks in advance
Pat
Hi Pat, thanks for getting in touch. There are many reasons why your system might not be working - each make and model of amplifier has its own ways of managing the signal so I can only give some general suggestions:
First of all make sure that you have selected the correct INPUT on the amplifier - many hifi amps have several inputs: phono, CD, tuner etc. Also, make sure that signal is actually reaching the input of the amplifier - you mentioned an equalizer in your post above - if this is a separate component try unplugging it and running the source directly into the amplifier itself.
Secondly, make sure that you have selected the correct OUTPUT - some amps have two sets of outputs, meant for two different sets of speakers. These are sometimes called A and B.
Finally, it is likely that your amplifier should be run in stereo mode - bridge mono mode is usually reserved for driving subwoofers.
Hope your can get your system working!
@@GLBProductionsMr. B. Thanks for responding to me. I should have also let you know that I did not use the XLR 1/4" connectors. I just attached the speaker wires in stereo mode. Should these connectors be plugged into channel one and channel two on the amp and into the equalizer.
The equalizer needs to be connected to the amplifier for sure, either via the XLR or 1/4" connectors. Left output of the EQ to channel 1 of the amp and right output of the EQ to channel 2.
@@GLBProductions ok. Will try. Also what is the best xlr and 1/4" brand name to purchase. Many thanks
Good Day,Sir i have a question how can i use my compressor limitter if my i have a stereo mode amplifier? I have a behringer xenyx1002fx mixer....how can i connect from my mixer to compressor limitter and to my stereo mode amplifier?
Thank you Sir.
You would need a stereo compressor/limiter in order to do this - one channel for the left and one for the right signal.
Good day sir,Thank you so much for your wonderful and informative explanation...
Hello Sir can you please explain how many speakers can be connected in bridge mode and how its done THANK YOU.
It depends on the impedance of the speakers and what the amplifier's minimum operating impedance is in bridge mode. See this video for more details: th-cam.com/video/l9L7uK7Xy0w/w-d-xo.html
