I am so happy that you made this video. As a car audio installer, I had a couple customers that were unwilling to take my word, even when I showed them the exact demonstration of continuity that you showed, that I had correctly installed their amp. One guy was absolutely convinced that his subs were only getting half the power because he was only using half the amp. I think that at my boss's direction I actually ran a second set of speaker wires to his box just to apease him. My MECP advanced certification wouldn't convince these people that I knew what I was talking about, but I bet that a popular TH-cam video that confirmed it would do the trick.
Happy to help! I don't know why guys always feel like the car audio shop is trying to pull one over on them... although I did have a guy today comment that "he's only recommending fuses because he sells them, you don't need fuses on wiring" so guess us YT guys can't be trusted either... 🙄🙄🙄
Use 4-channel home-audio wire, with 4 wires wrapped in a single cover. That way you can use both both connectors on the sub amp, plus whatever gauge fits exactly, times two, is likely thick enough. Your less observant customers will think the 4-stranded wire was specially made for sub amps. 🤣
yeah just add that second pair of wires, a 4-terminal plate and connect two wires to the air inside the box lol. remember, 15 minutes on youtube means you know more than experienced techs :)
I retired from 12v after 35 yrs,these amps remind me of 80s amps,i love it,memories of my beginner years with craig,kraco,sherwood,rockford,etc.love this channel 🤘
Just received my Lc1.1500 yesterday! Been dreaming of this day for a year. Im working with you now on a custom subwoofer box for my SQ5. Checking my email like every hour 😅 Always love your content, thanks for all the info!
Hi Kodi, I wrote a comment that my LC1-1.1500’s cooling fan is always on when powered. Like to hear from you if yours does the same. Feedback of a fellow owner would be welcome.
@@umtbozkr2358 I mean, the Amp has to stay cool but I guess if it's loud enough to hear, it can be annoying. I've used cheaper Amp before and the fans were audible and always on, but on my Audiocontrol or Phoenix gold, never really heard them.
@@dwilde649 I’m sorry, didn’t understand your comment D Wilde. The amp works perfect and delivers a good performance. Only the fan is constantly on and it’s not the most quiet fan. Normally I ran my woofer with a bridged Steg K2.03 with about 1000w RMS. When the fan went on you couldn’t hear it running. I replaced it by the Audio Control because it draws less current because it’s a class d amp. A class d amp shouldn’t get that hot; even without any load it gets hot.
I just bought a Polk mm1 10inch 4ohmDVC subwoofer and in the manual there is a diagram showing connection to a single pair of terminals on the subwoofer, now with that connection you will only be at 4 ohms but it can be done
I had to google this 2 hours before you uploaded for a Mosconi 1000.1, funny coincidence. You gave a lot more detail than the answer I found earlier, thank you!
There is actually one major advantage to bridge or use both the outputs on the dual that you did not mention, I would always bridge or use both outputs always if possible, why? it is very simple, This speaker block is internally connected on the PCB, if you use one pair you gonna push all load through 2 solder connections instead of 4, I had amps where this load got so high the joints exploded and the amp failed due to overload on these. if you use both outputs you gonna share the load on the terminals making such failure case much less prominent. However this applies more to cases when you load the amp with lower impedance thus making more current. But I had amps fail before I always started to use the terminals with all available outputs. you would actually gain a tiny but more power too as the resistance get slightly lower. I competed in audio a lot before and this is why I know. Every watt counts
Great point, and 4-channel home audio wire could solve the issue, eg 4 wire. Doubling the wires reduces the total AWG by 3, making it feasible to use a speaker wire (eg, 16 awg) that actually fits instead of trimming or using special tips to fit a monster sized wire, plus both connections get used. The 4-channel wire is better than 2 runs of wire, as the wires are bound into a single cover, minimizing impedance fluctuations.
Running to a dvc what advantage of running 4 conductors? Instead of just jumping them in my box that little bit less resistance will be made up by another 2ft chunk of wire
@@Spacecadet3890 The biggest benefit is that you reduce the load on each terminal since you run less current through each wire and terminal as they split in half you will have more power and less heat produced in the interconnects and wires. But in low power amps it gonna be a pretty small amount. I had an amp with more than 1KW power explode the solder joints on the speaker terminal because it was too much current for one single output. So it is just a matter of caring about your stuff but either way you connect is still gonna work unless it can’t handle the power in the long run
You explained that very well I my self already knew all this I'm just watch videos because I'm bored and have nothing to do but out every video I have watched you explained it a whole lot better then anyone else
Man I looked all over the internet you're extremely informative learned a lot from watching this video I really appreciate that I subscribe to your channel because you're worth really appreciate your knowledge with that thank you again
Great video on something very confusing when you’re newer to car audio!! 👍🏻 I do personally prefer to run one wire pair to the sub then run the other wire at the sub (Parallel). Instead of two wires back to the sub.
Im really glad u posted this vid,i have a different class D monoblock that has 2 terminal like this and my multi meter is or was older and mu kid attempted to ohm a live 120vAc circuit and it became um melted so was concerned about the ohm load to my amplifier which i usually keep at 2 ohms though i found the amp is 1 ohm stable but my question answered thank u
How about how to test a used amplifier on the fly? I was burnt picking up a Rockford Amp on Craigslist. Met in person, tested the continuity at the speaker leads, got home and it popped fuses left and right. Obviously i did not do it correctly. I have bought from a dealer or amazon every since then 2013.
love vid, keep the good work up❤. question I have is. if you have four 4 ohm subs and run each to series then parallel leaving two separate connections at 4 ohms then connect it to the amp like you showed. would the connection to the amp still be 4 ohms for all subs or does the amp parallel it again and make it 2 ohms for all subs?
Just look at it like the amp only has one output, yes 2 ohm is what the amp sees if i am understanding your question right - 4x 4ohm voice coils wired in series per pair then paralleled to the amp.
I just connected my subs to a mono amp with the dual setup like on the lC -1-1500 and can’t get my subs to thump everything else is connected correctly any idea what I’m doing wrong I did one to the positive and one to the negative
Hello Mark. First of all, I thank you for its contents, and I have a question for you (I have 4 speakers of 8 ohms of 480 voltage of each and one 6*9 low) what kind of amplifier should I use for my car without affecting anything. Please
Makes no sense. What is "480 voltage"? If you have 5 speakers total, use a 4-channel amp. Wire the 8-Ohm speakers in parallel, 2 to a channel. This gives 4 Ohms. Bridge the other two channels to the 6x9. Set the xover to LP of the 6x9 channels and to HP for the high speakers.
So, in theory, lets say you have a 2 ohm single coil woofer with built in wires that are too big for the connectors of the amp you are running ( and probably needs more power than the amplifier can push, but thats beside the point). If one was to machine som adapters that would accomodate those wires and be screwed in to the amp, that would share the load onto the solder points on the PCB? sort of like a Dual 1/0 AWG to 1/0 0 Gauge amp inputs but more fancy to not come into contact with each other?
There are some amps that conveniently put the positive terminals on one side, negative terminals on the other. So adding an adapter like this is much easier. But if it's configured like the amp in the video it's going to be hard to do.
So if I have dual outputs on my amp & 2 4ohm subs. Are you saying wiring both separately to 2ohms then connecting both pairs of each subs pos & neg wires to the amp directly will result in a 1ohm final load? Which essentially is wiring them in parallel but through the amp instead? Really need this answered. My box’s port is in the middle & I don’t want to drill a hole to wire them together if I don’t have to 😢
@kushmade1 I figured out the answer on my own; the answer is yes; you can wire two 4ohm subs individually at 2ohms, then connect them to the amp (if the amp is a monoblock) & the final load will be 1ohm. The speaker out terminals aren't two separate channels, but most monoblock amps offer an extra set of terminals for this exact reason, convenience. Hope this helps, man! :)
@@ijonnyproYou can't wire a 4 Ohm sub to 2 Ohms unless it has dual voice coils, which you didn't specify. If you're saying wire two single VC 4 Ohm subs together to get 2 Ohms, yes, but it is still 2 Ohms on a mono amp. It would only drop to 1 Ohm on a bridged 2-channel amp.
Yes you can or do like he was showing and run 2+ and 2- wires to amp so the wire won't limit power but it might not be even a noticeable difference. So it's bridged but kinda like 1 dual coil Is wired like 2 speakers. Either way works. 4 wires would be able to transmit more power But if the 1+ 1- and jumper wires aren't limiting ie maxed out then there wouldn't really be a benefit to the 2 more just It's like the 2 outer tires on a dullay truck when there's no load sure there's potential but not really needed when it's empty
Mono and bridged are not the same. You can have two separate channels running mono without them being bridged. Mono combines stereo signals into a single (mono) signal.
I have question that I would like your opinion on. Just so we are clear ALL variables are equal in this situation. Question - Is it more efficient to run two Amps separately on two separate subwoofers? Or is it more efficient to run one large amplifier on both subs? So we are clear. Two Alpine subwoofers that EACH take 400 RMS. On two 400 RMS Alpine amps or one 800 rms Alpine amp?
It makes no difference where the power is coming from all the subs see are power. Does not matter if it is one amp or two. The only difference it makes is on audio signal. You cannot run 2 different signals to two amps because they would play at different timing. Just run one audio signal to the input on amp one and then use the audio output on amp one to the input on amp two. So the audio signal is linked. Just make sure your amp has an audio output :)
@Pasler Andrew I was saying more for someone that might be using 2 5-channel amps and that 5th channel on each amp for each of your subs. They are identical amps with the same about of “efficiency” and power
@@peytonscoggin3746Actually, it does. Separate amps have separate power supplies, so this may be an advantage unless you assume the single amp has twice the power supply.
Hello thanks for your great work. I need help I'm using a subwoofer that's AC and I want you to help me convert the AC to DC so that i can use it in my car
Good video I had a question, if I have a secondary battery in the trunk do I run my amp that's in the trunk the 2 ground wires to the secondary battery negative terminal post ?
Is there any way you can make some videos on some good amps and DSP's made by other companies than audio control that are also good options for people that are building a complete audio system on a budget of a few hundred dollars to $1k?
JL Audo VXi series are the best if you have the budget. You'll need an installer with more brain cells than average because they can only be adjusted by special software on a computer.
Great video! Quick Question Can you tell me will this amp work on the tesla 16 volt battery system Im looking to and a sub but the last amp I used kept dieing out the 16 volt battery.
My kicker 1200 amp has two positive on the left n two negative on the right . I connected positive to the middle positive n negative to the middle negative . I was starting to think I needed to connect the positive the far left positive n negative to the middle terminal.
Quick question. The cable that connects the gain control switch to amplifier is too short to reach amplifier. What type of cable can I use instead of the one provided in my amplifier install kit? Looks like a 6C6P or Cat6 ethernet cable.
Can you wire a 2ohm dual voice coil subwoofer at 1ohm to a monoblock amplifier that’s rated for 1ohm or higher or will I need to wire the subwoofer to 4ohm to make it a 2ohm load at the amplifier?
So here is a question that I can't seem to find a video or diagram for. I have a Power Acoustik Vertigo 8000w monoblock. Can I hook 4 subwoofers to it? And if so how?
Great videos. I have a question reguarding this subject. I have 2 12" dvc 2ohm subs. I am going to wire them in series parallel into a 2 ohm amp. My question is do i have to feed one sub from the other in order to end up with 2 phm total load or can i wire both subs to the mono amp? Reason im asking is it will be a lot easier to wire each sub to the amp (single output amp) rather then feeding one sub from.the other as the terminal connections are much smaller. Thanks again . I found this channel looking for info on using a dsp for the first time
Please correct me if I'm wrong but if you bridge your sub on your amp aren't you getting the true value of the amp? I had a mtx amp that said if you hook up the middle set it's true 750 watts rms. Just left or right set gave 500 watts. I now have a phenox gold amp 1200.1 rms and I have 1-12" rockford p3 at 1 ohm. I do not have it bridged now for break in process but was wondering if I should bridge it to get the true 1200 watts. I know the sub is only rated for 600 watts but it hasn't stopped my 2-10" p3s in my other car. Love your vids too btw very informative 👍
Speaker wire size is one of my biggest pet peeves. Everybody with 1000w on a pair of 12s seems to think that they need 8 or 10 guage speaker wire! 😣 I know from experience that as long as your using good name brand OFC (SkyHigh✊) you don't need bigger speaker wires. I had no problems at all using 14 guage OFC on a 2000w rms system and when I upgraded to 4 12s on a 5k amp I used 12 guage. Some of these people are running POWER wire to their subwoofers and I'm just like 🤷🤦
I just got a 1600w 12inch skar subwoofer vented it is preloaded in a box wired to 1ohm 1600w peak 800w rms with turning frequency of 36hz and im an amateur and got the 1200w rms to 1600w peak amplifier and dont know anything to set gain lpf or subsonic but want to know how i can get the best sound out of my bass without it sounding wobbly or damage my subs how do i set those settings the easiest way
I do not want to put no speaker box in my vehicle just want to take out the original speaker an put other speakers so I was wondering what's the best speakers to use for bass and voice
I've just always assumed if it's a mono block with multiple connections, they they absolutely have to be connected together inside the amp, so it's apples or apples😂
Tap Plastics is a good source, for Cast Cell Acrylic (way easier to work with than plexiglass) as well as HDPE (cutting board material, also known as Starboard), for speaker adaptors and amp racks.
So I was wondering I installed two ten inch 300 watt subs in my jeep, and I am looking to buy a amp to push them. I had bought a loc2 pro controler with AccuBASS but it didn't work (maybe bad part) a regular controler worked just fine. My question is if I went with a amp that had AccuBASS would that get me the bass I want is so what would be the amp I would want to use to push them
Question: TIA I have RCA’s running from my deck back, when I plug in both red and white to the amp, my sun sounds muffled, when I plug in one, doesn’t mater the red to red or white to white, it sounds fine but seems like there is more the sun can give. Any ideas?
Hi Mark. Is it normal that the cooling fan off the LC-1.1500 is always on when powered. It’s been told to me that it’s normal, others tell me it should only turn on when it gets hot.
@@aycentroid it works fine, enough clean power. Only for a digital amp it gets quite hot; and heat is wasted energy. And one last thing; when the amp is shutting down, in the last second when shutting down it makes the subwoofer make a scratchy sound, like a kind of “backfire” of the voicecoil.
Because the positives and negatives are connectied does that make a parallel circut inside the amp so if i connect two subs with a 8ohm load each would it be seen as 4 ohms to the amplifier?
No. You are simply connecting the subs in parallel. This in itself produces 4 Ohms. Nothing to do with the amp. The amp senses 4 Ohms. It has no idea how many speakers are connected, nor does it care.
2-channel amps aren't monoblock. If you jumpered a 2-channel amp like the thumbnail, you'd fry the amp. If you bridge it, load will be 1/2 what the speakers are wired to.
How about if I got an 1 ohms amp but my subs are 2ohms my subs are 2 boxes of Sealed downward-firing enclosure with CompRT® 10" shallow-mount subwoofer and passive radiator my amp output are double so each are connected separately is this okay
So just to be clear, in the video u said that u can use either pair of positive&negatives. My question is can i use the the pos and neg on the outsides. The ones that arent right next to eachother? Seems theres less of a chance of them ever touching by using the outside terminals
@@CarAudioFabrication I am a recent subscriber to your channel.. You seem to know your stuff. I keep getting conflicting info on my 2, R-W12D2 Alpine R-types dual voice coils that I purchased a couple yrs ago. They are sitting in the closet brand new in the box still. They're 750w rms 2250w max 12's. Everyone keeps saying i should've got the 4ohms. W/e, its what I have to work with. What amp would you recommend to run the subs at 60-70% of their rms. I don't want to max out the subs, I want them to last. I'm upgrading my vehicles wiring to support more power and will have a farad capacitor. People say mono-block, 2 channel, 4 channel etc etc. Any help will be much appreciated. Thank you...
After watching your great videos I’m planning and building my own install, quick question I wanted 2 10” 300w JL subs as this looked better with my design but would I get better performance from a 600w 12”? Or would it be very similar? Keep the great content coming 👍🏻
Question, my amp is a audiopipe apmn 1ohm stable amp and has those two terminals and im trying to connect both my 2ohm subs at 1ohm... Can i wire each sub at 1ohm and then connect each to there own terminal and still get 1ohm??? Plz help
I have a mono block amp but I have 2 Alpine Type E DVC. My question is how do I wire them inside the enclosure ? I understand that the two pairs of outputs are the same thing. I just need to know how the subs inside the box are supposed to be wired ?
Parallel, positive to positive, negative to negative will result in 1/2 the voice coil rating. Series would double the Ohms. Series would be wiring a jumper from one sub's positive to the other sub's negative, then running the two remaining terminals to the amp.
am i correct to say that it doesnt matter if i connect double positive and double negative wires to one sub woofer , vs just connecting one positive and one negative to one subwoofer? thanks!

Your correct about the amp, but with the Sub not all the terminals need to be connected if you want to run 4ohm, 2ohm or 1ohm etc

What size speaker wire is ideal for connected the sub to amp ?
depends on subs rated power, but for most people, 12-10 gauge works fine. I use 10 gauge on my sub thats rated for 1000 watts

@kushmade1 I figured out the answer on my own; the answer is yes; you can wire two 4ohm subs individually at 2ohms, then connect them to the amp (if the amp is a monoblock) & the final load will be 1ohm. The speaker out terminals aren't two separate channels, but most monoblock amps offer an extra set of terminals for this exact reason, convenience.
Hope this helps, man! :)
@@ijonnyproYou can't wire a 4 Ohm sub to 2 Ohms unless it has dual voice coils, which you didn't specify. If you're saying wire two single VC 4 Ohm subs together to get 2 Ohms, yes, but it is still 2 Ohms on a mono amp. It would only drop to 1 Ohm on a bridged 2-channel amp.
What is the best connector for subwoofer quick disconnect?
It's just like a car battery with terminals on the top and sides. They're connected together. Doesn't matter which you use.
Hi Mark,
What's your pick - JL audio or Focal?
Very good explanation !! Thanks
I have a mono amp with L/R INPUT and the signal coming from dsp has 1 rca coming out should i use a split rca cable?
On a dual voice coil sub can you run short wires between both negative terminals and positive terminals. Then run a single neg/pos to the amp?
Yes you can
or do like he was showing and run 2+ and 2- wires to amp so the wire won't limit power but it might not be even a noticeable difference.
So it's bridged but kinda like 1 dual coil
Is wired like 2 speakers.
Either way works. 4 wires would be able to transmit more power
But if the 1+ 1- and jumper wires aren't limiting ie maxed out
then there wouldn't really be a benefit to the 2 more just
It's like the 2 outer tires on a dullay truck
when there's no load
sure there's potential but not really needed when it's empty
Wait so I bought dual 8in skar sdr subwoofer with 1400 watts can I use a skar mono amp with 1200 watts would it be compatible
4th. I’ve been doing this for years 😂 be sure you have it tuned properly though
The jumpers in mono is like Bridge mode in power amplifiers. Is it the same?
Mono and bridged are not the same. You can have two separate channels running mono without them being bridged. Mono combines stereo signals into a single (mono) signal.
I have question that I would like your opinion on. Just so we are clear ALL variables are equal in this situation. Question - Is it more efficient to run two Amps separately on two separate subwoofers? Or is it more efficient to run one large amplifier on both subs?
So we are clear. Two Alpine subwoofers that EACH take 400 RMS. On two 400 RMS Alpine amps or one 800 rms Alpine amp?
It makes no difference where the power is coming from all the subs see are power. Does not matter if it is one amp or two. The only difference it makes is on audio signal. You cannot run 2 different signals to two amps because they would play at different timing. Just run one audio signal to the input on amp one and then use the audio output on amp one to the input on amp two. So the audio signal is linked. Just make sure your amp has an audio output :)
@Pasler Andrew I was saying more for someone that might be using 2 5-channel amps and that 5th channel on each amp for each of your subs. They are identical amps with the same about of “efficiency” and power
@@peytonscoggin3746Actually, it does. Separate amps have separate power supplies, so this may be an advantage unless you assume the single amp has twice the power supply.
Hi question could I use two car amps 2500 to power one big dvc sub
thank you sir!
Thank you!
Hello thanks for your great work. I need help I'm using a subwoofer that's AC and I want you to help me convert the AC to DC so that i can use it in my car
Good video I had a question, if I have a secondary battery in the trunk do I run my amp that's in the trunk the 2 ground wires to the secondary battery negative terminal post ?
You should be using a dual battery isolator if you run two batteries.
Nice thumbnail lol. Definitely added another reason to click on the video 🤣
Always love to give visual examples so folks can better understand!
@@CarAudioFabricationSo using the two outside terminals is bad? I also bridge my subwoofers 🤔🤔🤔
Is there any way you can make some videos on some good amps and DSP's made by other companies than audio control that are also good options for people that are building a complete audio system on a budget of a few hundred dollars to $1k?
That’s like asking Lebron to wear some Reeboks
I don't think I could have done better than the kicker key auto eq did. I do wish it had more power though
DIY Audio guy made video like that today lol
JL Audo VXi series are the best if you have the budget. You'll need an installer with more brain cells than average because they can only be adjusted by special software on a computer.
Great video! Quick Question Can you tell me will this amp work on the tesla 16 volt battery system Im looking to and a sub but the last amp I used kept dieing out the 16 volt battery.
Why would you use a 16 volt battery? You wire it to the 12 volts on the main battery.
My kicker 1200 amp has two positive on the left n two negative on the right . I connected positive to the middle positive n negative to the middle negative . I was starting to think I needed to connect the positive the far left positive n negative to the middle terminal.
This is great clear and easily learnable. Thanks mark looking forward to learning more later
Quick question. The cable that connects the gain control switch to amplifier is too short to reach amplifier. What type of cable can I use instead of the one provided in my amplifier install kit? Looks like a 6C6P or Cat6 ethernet cable.
You must have a hella long vehicle. I usually have to bundle six feet of cable because they are so long.
This is great information unless you live in Florida.
Dam...got excited per the thumbnail thinking there was some kinda wiring trick.
Can you wire a 2ohm dual voice coil subwoofer at 1ohm to a monoblock amplifier that’s rated for 1ohm or higher or will I need to wire the subwoofer to 4ohm to make it a 2ohm load at the amplifier?
So if you put a dvc sub with 4 wires going to the amp does that wire it in parallel?
Yes.
So here is a question that I can't seem to find a video or diagram for. I have a Power Acoustik Vertigo 8000w monoblock. Can I hook 4 subwoofers to it? And if so how?
If you know how to wire and you’re confident behind your wiring work
No such thing as an 8000 watt Power Acoustik. That amp is rated 850 watts. Likely that it doesn't produce half this.
Great videos. I have a question reguarding this subject. I have 2 12" dvc 2ohm subs. I am going to wire them in series parallel into a 2 ohm amp. My question is do i have to feed one sub from the other in order to end up with 2 phm total load or can i wire both subs to the mono amp? Reason im asking is it will be a lot easier to wire each sub to the amp (single output amp) rather then feeding one sub from.the other as the terminal connections are much smaller. Thanks again . I found this channel looking for info on using a dsp for the first time
Please correct me if I'm wrong but if you bridge your sub on your amp aren't you getting the true value of the amp? I had a mtx amp that said if you hook up the middle set it's true 750 watts rms. Just left or right set gave 500 watts. I now have a phenox gold amp 1200.1 rms and I have 1-12" rockford p3 at 1 ohm. I do not have it bridged now for break in process but was wondering if I should bridge it to get the true 1200 watts. I know the sub is only rated for 600 watts but it hasn't stopped my 2-10" p3s in my other car. Love your vids too btw very informative 👍
Speaker wire size is one of my biggest pet peeves. Everybody with 1000w on a pair of 12s seems to think that they need 8 or 10 guage speaker wire! 😣 I know from experience that as long as your using good name brand OFC (SkyHigh✊) you don't need bigger speaker wires. I had no problems at all using 14 guage OFC on a 2000w rms system and when I upgraded to 4 12s on a 5k amp I used 12 guage. Some of these people are running POWER wire to their subwoofers and I'm just like 🤷🤦
The main thing is to make sure connections are tight. When you have loose connections is when things melt.
Thank you so much! How can reach out to you if i have a question?
I just got a 1600w 12inch skar subwoofer vented it is preloaded in a box wired to 1ohm 1600w peak 800w rms with turning frequency of 36hz and im an amateur and got the 1200w rms to 1600w peak amplifier and dont know anything to set gain lpf or subsonic but want to know how i can get the best sound out of my bass without it sounding wobbly or damage my subs how do i set those settings the easiest way
Thx so much
I imagine it has four connections to support a dual voice coil subwoofer… different variables for different setups
I got two kicker ten inch to ssl amp I got it hooked up right I get a wining sound when I press the gas on my car
Buy a real amp. Doesn't it have a low-pass crossover? You should never hear an alternator through a crossed over sub.
Can we run mono amps at home ? Please guide
It is quite common, moreso than in cars.
Is it possible to wire two 4 ohm DVC down to 2 ohm impedance?
No. It can be 1, 4, or 16.
I do not want to put no speaker box in my vehicle just want to take out the original speaker an put other speakers so I was wondering what's the best speakers to use for bass and voice
I've just always assumed if it's a mono block with multiple connections, they they absolutely have to be connected together inside the amp, so it's apples or apples😂
unrelated question to your current video, but where do you get sheet acrylic used for custom racks, or speaker mounts?
Tap Plastics is a good source, for Cast Cell Acrylic (way easier to work with than plexiglass)
as well as HDPE (cutting board material, also known as Starboard), for speaker adaptors and amp racks.
So I was wondering I installed two ten inch 300 watt subs in my jeep, and I am looking to buy a amp to push them. I had bought a loc2 pro controler with AccuBASS but it didn't work (maybe bad part) a regular controler worked just fine. My question is if I went with a amp that had AccuBASS would that get me the bass I want is so what would be the amp I would want to use to push them
If it is a late-model jeep, you may need an LOC with loading resistors.
Does this also apply on old school amps
Yes. A mono amp is one channel.
HOW DO YOU REBOOT OR RESET AN LC1.800 OR USE THE JUMPERS ON THE INSIDE OF THE AMP
Are Rockford Fosgate as potent as in the 90's..?
I am using a powered sub and now my radio doesn’t have any sound coming from the speakers how do I fix it so it works properly
Question: TIA
I have RCA’s running from my deck back, when I plug in both red and white to the amp, my sun sounds muffled, when I plug in one, doesn’t mater the red to red or white to white, it sounds fine but seems like there is more the sun can give. Any ideas?
One of your speakers is wired backwards. Reverse the positive and negative on ONE of the channels.
Hi Mark. Is it normal that the cooling fan off the LC-1.1500 is always on when powered. It’s been told to me that it’s normal, others tell me it should only turn on when it gets hot.
If everything else works then I wouldn't be too worried. With 2 failure states, always on or won't turn on, your's is ideal.
@@aycentroid it works fine, enough clean power. Only for a digital amp it gets quite hot; and heat is wasted energy.
And one last thing; when the amp is shutting down, in the last second when shutting down it makes the subwoofer make a scratchy sound, like a kind of “backfire” of the voicecoil.
Because the positives and negatives are connectied does that make a parallel circut inside the amp so if i connect two subs with a 8ohm load each would it be seen as 4 ohms to the amplifier?
Yes, correct
No. You are simply connecting the subs in parallel. This in itself produces 4 Ohms. Nothing to do with the amp. The amp senses 4 Ohms. It has no idea how many speakers are connected, nor does it care.
Question? Is there ONE amp that does both SUBS(2)(skar10"800w) and SPEAKERS(4)(ds18) and tweeter 🤔
-I'm looking @Skar amp 2000?
Does it work for all class D Amps with 2 channels
2-channel amps aren't monoblock. If you jumpered a 2-channel amp like the thumbnail, you'd fry the amp. If you bridge it, load will be 1/2 what the speakers are wired to.
How about if I got an 1 ohms amp but my subs are 2ohms my subs are 2 boxes of Sealed downward-firing enclosure with CompRT® 10" shallow-mount subwoofer and passive radiator my amp output are double so each are connected separately is this okay
If you wire two 2-Ohm subs to a mono amp, the load is 1 Ohm.
Most amps tell you to wire your subs like this
So just to be clear, in the video u said that u can use either pair of positive&negatives. My question is can i use the the pos and neg on the outsides. The ones that arent right next to eachother? Seems theres less of a chance of them ever touching by using the outside terminals
They are internally paralleled. It makes no difference which combination you connect.
@@CarAudioFabrication thanks boss
@@CarAudioFabrication I am a recent subscriber to your channel.. You seem to know your stuff. I keep getting conflicting info on my 2, R-W12D2 Alpine R-types dual voice coils that I purchased a couple yrs ago. They are sitting in the closet brand new in the box still. They're 750w rms 2250w max 12's. Everyone keeps saying i should've got the 4ohms. W/e, its what I have to work with. What amp would you recommend to run the subs at 60-70% of their rms. I don't want to max out the subs, I want them to last. I'm upgrading my vehicles wiring to support more power and will have a farad capacitor. People say mono-block, 2 channel, 4 channel etc etc. Any help will be much appreciated. Thank you...
@@jayirvin3629Nonsense. Just wire each speaker in series with itself, then parallel to a good monoblock amp. This is 2 Ohms.
After watching your great videos I’m planning and building my own install, quick question I wanted 2 10” 300w JL subs as this looked better with my design but would I get better performance from a 600w 12”? Or would it be very similar? Keep the great content coming 👍🏻
I think you'd get more performance with the 2 10s, not sure tho, don't take my word for it.
depends on a lot of things but the 10's would probably come out about 1-3db ahead.
So I put in two alpine 300 watt 10s I was wondering what amp u used to push them
Question, my amp is a audiopipe apmn 1ohm stable amp and has those two terminals and im trying to connect both my 2ohm subs at 1ohm... Can i wire each sub at 1ohm and then connect each to there own terminal and still get 1ohm??? Plz help
If you wire two 1-Ohm subs in parallel, it is 1/2 Ohm. You would want to wire them in series, resulting in 2 Ohms.
I have a mono block amp but I have 2 Alpine Type E DVC. My question is how do I wire them inside the enclosure ? I understand that the two pairs of outputs are the same thing. I just need to know how the subs inside the box are supposed to be wired ?
Parallel, positive to positive, negative to negative will result in 1/2 the voice coil rating.
Series would double the Ohms. Series would be wiring a jumper from one sub's positive to the other sub's negative, then running the two remaining terminals to the amp.
Respect bro
am i correct to say that it doesnt matter if i connect double positive and double negative wires to one sub woofer , vs just connecting one positive and one negative to one subwoofer?
thanks!
If you double wire to the same locations, it doubles the current capability of the wire.
I'm trying to figure out the connection from the 3317 to the head unit can you please help
Is it safe to connect an amp at 1ohm to a 2ohm sub?
It isn't possible. The speaker determines the load on the amp. How are you going to run the amp at 1 Ohm if the speaker is 2 Ohms?
