- This method will yield you perfect results every time, and you dont even have to use a multimeter or a scope if you dont want to. It just uses splitting of the available coils in a uniform way plus simple phase inversion.

This is quite possibly the best information/demonstration on this topic that I’ve ever seen. Thank you for sharing this. It’s videos like this one that make searching through youtube absolutely worth it.
I'm officially addicted to your videos due to the fact that the content is so rich in information that I'm learning at a rate I find to be extremely satisfying. When I found your amp repair vids it was such a big find for me personally and I've been finally learning things about amps and electronics in general that I've been dying to know for a long time. Thank you for the very potent and deeply interesting content you post.
This makes it all worth it, thanks!
Can we find those 19 people who disliked this video and hook up their brains to a car battery?! This is the most brilliant free information I've ever encountered on TH-cam
Pure Ignorance.
Too much effort is required for their lazy asses. Those people want everything for done for them. (Or they aren't bright and couldn't understand the well explained process)
@DCAudioFTW was about to come up with the idea of spending all of my money on some sweet steve meade gear to get some steve meade (SMD) treatment
@DCAudioFTW seems like it, shoves his products down his fans throat, and they sure do love that, i mean, the products are working but he talks down to anyone not doing it his way with his branded products, and how he also talks shit to any criticism, insecure little b
@DCAudioFTW he is just slapping his name on everything of damore
You are absolutely brilliant! This is the third video I have watched by you that has given me an "ah-ha!" moment! You have a brilliant way of explaining things.
Thank you so much! I am getting my 2nd amp back from repair today and have been gain matched and will now switch to this way.
thats genius my guy
I
💯%. I've been cracking my skull open thinking of how to get that done perfectly
Thank you for this. Such a simple solution I've never thought of before. Absolutely brilliant!
This is amazing for anyone who lacks the required scope in order to do this analog/digitally. Instead you show an excellent way to match the amplifiers so that they work together instead of against each other in the subwoofers two coils. Awesome video man!
i told a friend of mine about this video and his system sounds realy good now, keep up the video's man, I love them
Using phase cancellation for setup, cheap simple and gets results, genius!
This video just taught me the most . Out of anything anyone has taught me about amplifiers. Thank you. I liked and subscribed. Cant wait to learn more from you!
great to hear buddy!
Best information on gain matching and strapping amps anywhere! Thank You !!!
So glad I found this video and your breakdown! This is what I was considering doing with my two subs and amps. Just saw the reason for amp power output to be as close as possible. You are a very smart man and bring a ton of knowledge and common sense into the car audio tuning and setup game.
I did it with 4 15's on 2 3 k's. It took alot of 8 gauge wire (alot) but it was worth it. This guys a genius! Thanks for the tip!
Brother u are an ocean of knowledge which can really benefit the community. Keep up the good work. Really appreciate your videos.
Now that you started sharing all this amazing stuff. I love you mate. Thats genius. Thank you so much!!
the best video on this subject ever!!!
one of my take away's is most bass heads don't have the tools or knowledge to link amp's together.....or run multiple amp on multiple woofers.
Very smart way for phase alignment I would have never thought of this.
Totally want to try this in my spl setup and see what gains I see! Awesome!
JeepAndBass u try this? I did and seems to be louder and more responsive also holds voltage better
Whats up Ray I just did this to my set up. So far so great for me. How did this method work out for you?
What’s up Jeep & bass. Did you really try it up. Or you just used the smd cc-1 ?
@@93da9teg really?
So did you try it?
You're a genius, Sam. Thanks for sharing
One of the best demonstration video on TH-cam
This is pure brilliance, thanks, learnt loads! 😊
It's been said before and I'll say it again, freakin' genius. It's amazing what you can do when you understand the technology you're working with.
ive done this same practice for years :)
amazing video, its quite hard to explain this method to friends that have a ton of money in stereo's :)
always turns out the best for me!
This is an absolutely fantastic tutorial! This is exactly what I will need to do for my 8x JBL W12GTI's on 2 5k's when it gets built. Thank you for your concise explanations! You're the man!
Did you build this?!? 8 w12gtis 🤯🤯🤯
@@MikeJrOfficial I did not build it yet, but I'm going to. I actually have 14 of those lol
@@altonknerr4864 wow! I have 2 W15GTi's they're animals, just need to get the proper power. I have 2 CAB-45's, I'm going to see what they'll do at a 1.5ohm load on one of those amps
Thank you very much sir after I watched this video I finally fix my audio system... Its been a long time for me to figure out what to do cause my ear tells me I have a signal phase issue even though I gain match my amplifier at exact output voltage. You are a great teacher for me sir and from now on I will watch and subscribe on you... 👍👍👍👍👍👍👍👍👍👍
Never see or heard this before but it's a great idea keep up the good work bro
WOW bro for as young as u r u definitely have a lot of Knowledge and Skill im really glad i found ur channel and the wat u explain things makes it so much more easier to understand im shr i speak for most of the fellow BASSHEADS out there when i say i truly appreciate all ur informative videos bro 👍🏼👍🏼✌🏼💪🏼🔈💪🏼🔉💪🏼🔊
This is similar to how ac generators are phase matched when hanging up or connecting to the grid except you just use a bulb across each phase. Different way of wiring it but the ideas the same, you "tune" for a no bulb. Just as you are for no movement. Novel and simple nice one.
nice. This would explain the issues I was having with my two hifonics amps.
The way he wired those subs is amazing. Never thought about splitting the subs like that.
Hello and greetings from the USA. Great video I will give this a try with my 2 dd m2b amps. I will keep you posted.
Ohhhhhh! Love this video! So simple & will be correcting 2 things on my system immediately.
Im totally phased out 😮
Nice explanation bro.
Nice thinking out the box, another phase gremlin identified & dispatched. Those tweaks will also improve the transient response, as well as the additional gain.
I would love to see the o-scope output after you've done the tuning as you suggested. Looks like great advice, but proving it out via scope would be great.
be thankful for learning something and do not ask for proofs!!!!! this man is a genius!! he want upload a video if it is not a 100% sure for what he is doing!!! the video is the proof!!!!!
This works great I just did it on my setup and wow it's amazing
@@monstral6331 Exactly. Thank you!
@@troyhooper6896 I did it as well. I have 4 15" HDX3's on 2 s12250's and it works great. I wired the subs as he explained but I haven't switched the polarity to make sure they are perfectly equal yet, but the subs look to be moving in perfect unison at all frequencies.
@@Hertzsogood219 if you're going to start that process you need to finish it all the way through
This is absolutely genius!!!! Thanks for the info!!!
This is a great video. Thank you for the knowledge barevids.
AWESOME DUDE! FREAKING GENIUS!
Wow, great video. Thanks for posting!
I done this and it worked great. 2 Cab 4500s and 4 Skar VXF 15s. Had a significant gain in output. Thanks for the great info.
idk if you will see this but did that hold up well, i might do this with 2 cab 45s and 2 sundown x15s
@Kaz Sieja yes it definitely did. Still like that now. Just make sure you completely follow what he says and will work out great. The only thing I've noticed by doing this is that the amps tend to run a bit hotter for some reason. So if you have them in an area that doesn't have good air flow then might not be a good idea. I have since put several fans and a thermostat on mine and haven't had any issues at all. Hope this helps
@Kaz Sieja are you wiring to 1 ohm or .5 ohm?
Damn bro ur a badass u kno ur stuff im glad i subscribed to ur channel ur videos r very informative thanks and keep em coming ✌🏼🔈🔉🔊
Simply brilliant! Bravo!
Great info, presented excellently! Louis S.
I had a question about this!!! Very very good information I loved it! But after you match the subs and then switch the positive and negative back do you then set the gain? Or have all the gains set and then turn the volume down and then use a low voltage to phase and all that like forwards the end of the video?? I would love how to do this perfectly because then I would rather gain match rather then strapping
Thank you so much for the great info ! Keep Bangin !!!
Fascinating method.
That is awesome fella thanks 🙏🏾 for sharing
This is Awesome. i am trying this on my next build.
Brilliant! Can't wait to to use this information on my upcoming build. 4 Skar evl-15s on 2 skar SKV2-2500.1D
Protip: Avoid Skar.
Very good I never thought of doing it that way
Nice! I've been having trouble, definitely doing this.
Bro ur a badass wen it comes to setting up systems i give u 👍🏼👍🏼 for this video i bet everyone tries this i can tell u r a really smart dude but the way u explain it for us dumdums makes it so much easier truly 💯 appreciate all of your videos ✌🏼💪🏼🔈💪🏼🔉💪🏼🔊
I'm just about to go from a single DC 3.5k on my 4x sav2 15s, to a pair of JP23's and was curious how I was going to make sure all the amp where going to be identical without a dd1 - only using a multi meter. I don't like strapping either. So I am going to give this ago. Appreciate the video, I found this extremely helpful
How did it work out for you
Love your videos man not really an spl guy but this is still great info for any basshead
Thanks bro I never even thought of that
That's a great way brother I'm goin to have to give this a go when I hook my other amp up
Hi there. I have just finished setting up the system in my 2011 E90. The source unit is a DEH 80PRS and the amplifier is a JBL GTR 7535. There is a dilemma I have run into. When testing for max volume at the headunit, depending on where I connect, it clips at different volumes, so for the sake of argument, on the front channels it clips at 59 out of 62 on the rear it clips at 60 out of 62 and on the sub it clips at 58 out of 62. This part is fine, I just stick to 57 and plug the RCA's into the amplifier. When I hook my mini oscope to the speaker output channels, even before touching the gains, I have to turn the volume down at the headunit to 50 in order to get a clean signal. There is a switch on the amplifier that says "Low, HI1,HI2" and the manual says to use the setting at Low if using line level signal. Now the thing is on the sub channel, I don't need to touch the gain at all and the other two I need to slightly. Is the amp underpowered? Is there something I am missing? Thanks
Great video love your work
Great and informative video, thanks for sharing.
G E N U I S
Thank you for always taking time to share!
Expert level 10 information right there.
Yes sir.
Great video and tips. Thanks
Very clever Idea! Great!
Very informative videos. Thank You.
Best Vid on this Subject..!!.Great Work..!!.thnx..💐🙏☝👑
Thx for the cool video! What type of amps are those? How do we know it’s not his amps or difference the circuits due to parts tolerances? Does the SPL class d bass amps using up to 20% tolerance parts cause this ???
First off I have to say that you are absolutely brilliant sir! I have two questions though. First, do you think the Hantek PC based oscilloscope would be a good budget friendly tool to do this? It's an 2 Channel oscilloscope under $100. Secondly, is it the same process for gain matching 2 amps without the phase flip option that each power one Subwoofer? And lastly is more of a request. I know this is a bit of a lengthy explanation, but do you think it's at all possible to do a step by step tutorial? I feel like the straight forward step by step tutorial would be a great addition to your videos, and this current video can be used to reference back on for explanations. But all in all you get a solid 20 on a scale of 1-10 brother! You definitely hit the nail on the head and the ball out the park! BASS ON!!
Enrique Lomeli Thank you for the kind words sir! Perhaps I will look to do a step by step. I also have a video planned to show people how to set clipping point without a scope of DD1. Hopefully that should be useful as well.
For two amps each running one subwoofer, yes, simply wire one of each coils to one amp, and the other two coils to the other amp, so that each amp is powering both subs, but only one coil from each. Find your clip point the normal way, then flip phase on amp 2, play low volume 20hz sine, and tweak gain of amp 2 until cones are dead still.
That scope would do the trick for sure, I am not often a fan of software based scopes due to lag and how they're kinda stuttery to work with. For reference, my HP scope here was £150 used and maybe the best investment I ever made!
wow that makes perfect sense!!!! I guess you learn something everyday lol
Barevids, absolutely love the videos! I have a question myself.
Currently running 3 dvc d4 subs at .67 getting split on strapped 5ks and obv my amp protects near my max volume bcuz of how low my ohm load .....I've also tried to run 3 coils per amp, but got crazy impedence rise. I tried multiple different ways to wire these none of which Im happy with. Seems the most I can clamp from two 5ks is 3100w, which doesn't seem right to me. Rn all my coils are wired individually with 12g all ran to the same box terminal then my strapped amps attach to the box.....I was wondering what would happen if I unstrapped them, and ran both amps to a distro block and ran my speaker wires to the distro?
So cool. Good tip to know
Amazing idea!
i did a duct tape patch on two matching subs glued the tape patch i wonder if it might have changed the phasing with the unkown amount of extra wight on the cones the both had alot of holes and i used random sized patches and i tried to keep the wieght even across the cones but i didnt think about the difference between two cones in a common chamber
I remember discovering this method with you at Modnats
HOWEVA!!! Great vid bro..Im going to try it tomorrow
So I can do exactly the same with two 1 ohm DVC subs and two amps? (Gladen RC 3200c1 which run stable on 0,5 ohms) ?
That's amazing!
Will this work with 2- MD8k's on DC lvl 4-15's? Thanks for your videos and knowledge!!!
This is similar to how I find the perfect crossover frequency/slope between subs, mids and tweets. Reverse polarity on one driver, play with gain and delay(phase), look for the deepest most symmetrical null you can get, then reverse the polarity back.
love the video. I have 4 exact amps/Alpine. trying to match each amp to each coil for 2 Alpine subs. each coil is 4 ohm. how do I best match this. meaning 2 amps per sub
very interesting i will give it a try next time i'm changing something to my box
I hate how smart you are it makes me feel so dumb lol I'm kidding im glad you're smart and kind enough to share your knowledge with everyone
Two drivers and two amps same enclosure how you make sure they are in phase and getting the same power
Great video. thank you
big trick ... have u solution for subs have only one coil? in same enclosure does it work?
Thank you for sharing this. I am currently using 2 amps on 4 Subs just like you've shown in this video and I have the inputs configured as master / slave but each amplifier is individually running its own pair of subs rather than strapping the outputs together. I just assumed the amps would be pretty closely matched this way but it looks like I'm probably wrong. I will definitely try what you've shown in this video.
Update: I haven't rewired the subs yet but I did check the output voltages and found a significant difference between the output of the master verses the slave amplifier. I forget exactly what it measued, but basically the slave amp always had less output than the master even when I tried swapping them around. I ended up setting the amp gains independently as close as possible and that alone made a noticeable difference.
Love it! Really glad to hear it helped.
barevids I was hoping I could still strap these amps to effectively drop the ohm load occasionally for burps, then go back to 1 ohm per amp for daily use, do you know if there's any way I could correct the issue of the slave amp running lower than the master? The controls do nothing on the slave amp so there's no way to turn the gain up or anything. It doesn't seem to matter which amp is used as master and which one is the slave, it always has lower output voltage on the slave amp. Is there anything internal that I could tweak?
Man I love your channel I was hooked after just one vid about box rise. Great insight. Where did you study.
No study, just trail and error, and logical thinking
I need to hookup 2 amplifiers to a factory Uconnect radio using the High Level inputs. I must use resistors in parallel with the signal speaker wires to avoid the channel shutting off. I am stumped as to the best way to split my rear signal speaker wires into 3 parallel connections 1 way to the AB rear channel mids, 1 way to the BD subs, and 1 to the 47 Ohm resistor.
My front signal speaker wires will be split 2 ways to the in dash speakers and to the front channels of the AB amplifier front mids.
In total the 4 channels of my radio will have 2 parallel connections on the front channels and 3 parallel connections on the back.
What are some things I need to look out for?
I can't afford an Audiocontrol LC7i even though it is exactly what I need.
That's was a great idea... Man.. Really.... Change the life of subwoofers
I have a question, you say in one video that you should set gains with subs connected to amp for proper load on amplifier... but if I'm running 2 amps, 2 dvc subs split down the middle, i.e. left coils on amp 1 and right coils an amp 2, how would I properly set the gains on each amp with speakers hooked up and not hurt the speakers? I do have a o-scope and multimeter, so I assume I wouldn't have the speakers connected to set gains, just check the phase after I set the gains.... hope I'm asking this right.
Ok.. I’ve got 2 2500s strapped at .66 .. the only way I can do what you explained is go back to a 1 ohm load on each amp.. my question is could I just wire my coils like you said and even the subs out , and still keep my ohm load? Even though the amps output might be different
This is exactly what I have been looking for I've got 3 subs and two amplifiers.
Very hadny piece of information thnx for sharing
I did this with my setup an yes i stand behind this method 100%
What if your subs are in 2 separate boxes, will you still have the same problems and if so will this solution still work?
Brilliant!
Thanks for the info
And doing this last part buy flipping the phase on the sub, isn't causing any problems back into the amp (we r kinda joining positive and negative together correct)?
I'm about to try it with two DD 2500a. I think this is way smarter than strapping. N I trust u over anyone with car audio at the moment haha. Just the phase flipping thru me off.
To me it's seems to b like accidently touching ur positive and negative speaker wires from the amp together? Thanks Sir.
U say low power 5 to 10 watts or so but still that scary to me.
Would there be any difference if using full bridge amps or would they work the same?
very good explain thanks
Could you just flip the positive s on both amps there for the positives would be fliped an the negatives would come from one amp am the other ?
