How to Connect Multiple Amps And Wire Up A System

[@juanvega5773]

Great video well explained to all the installers out there learn the right way 💯💯👍🏻👍🏻

[@trinity5611]

Thank you for taking the time to explain this stuff! Do you have a video on adding a second battery for car audio?

[@Blackmajic21]

This is so educational and helps me gain confidence in fixing my system that wasn’t installed to my liking. I would like to get your manual.

GOD BLESS PEOPLE LIKE YOU WHO TAKE THE TIME OUT AND EDUCATE. THANKS

[@tomasvihaan1048]

i know it's kind of randomly asking but does anyone know a good place to watch new series online ?

[@riveralec8838]

@Tomas Vihaan I would suggest flixzone. Just search on google for it :)

[@robertdistasio6715]

Omg, I was having trouble waking up the amps.they kept flashing as they weren't getting enough power. I watched the whole video saying to myself I know I did this right. Then in the very end of the video I watched him flip the breaker and realized my breaker was off, lol. Thank you!

[@MrAStompy]

Thanks man. One of the best car audio videos I have seen and you deliver well! Where can I find that PDF you mentioned?

[@AnthonyDiSano]

This video is wonderful. I have been doing mobile electronics / installations for almost thirty years (professionally for several years in my late teens/early 20's) and I've watched a lot of KZbin videos on the subject. In my opinion this video has some of the most correct/accurate information packed into a relatively short amount of time, that I've ever seen. Basically zero misinformation or bad advice. My guess is this guy has been doing this for a long time... Make sure to LIKE this video and say Thanks to the guy for taking the time to make this video and spread good advice/practices. The more people that LIKE this video, the more people that will see it! (and there will be less fires / blown up electronics in the process!)

[@ubersmash]

I appreciate the info about the horrible cat noise caused by poor ground wiring....have been trying to get rid of that for a long time....thanks.

[@MrTimdtoolman1]

Thank you so much, this is exactly what I needed to know. Thank you for the free education. I watched this 11 months ago (because I am a sub) and had no real need at the time but I am installing 2 small amps now and this info is priceless.

[@AzzenGear]

Thanks Lessco, digg the info you give out. I'm looking to run a 5 Amplifier system. The main amp is a 5 channel that will run front components, rear coaxial, and 2 door shallow mount subs. As you can see that pretty much takes up the front, rear, and sub RCA's from the back of the head unit. My question is what or how can I get a signal to the other 4 amplifiers I plan on having to run the 4-15 inch subs? Think you can do a table layout or drawing video on how I can pull this off. Thanx

[@cliftonduggins1023]

Thanks for the info ...I been doing my own car stereo systems for a long time...love it...I like for it to look good and sound even better...I never skip an educational video like yours..I m interested in that pdf you mentioned...thank you so much..god bless

[@BrianHruby]

I just watched this. Great video. You mentioned within the video that you have done several videos about using relays. And I believe you mentioned videos specifically for wiring a relay to power multiple amps with the remote turn-on wire from your head unit. I'm having a hard time finding this video, if it does exist. Thanks.

[@staffordcreates6874]

Howdy from Texas! Great tips with very thorough explanations. Much appreciated.

[@MrDazdavies]

thank you for teaching me its never to leate to learn.. you very good keep it up daz

[@ethancass6885]

The Fused distribution block is not for protecting the equipment. It's for protecting the wire! The fuse you have installed on any wire should always be to match that wire's length and gauge. Whenever you split the power into several smaller gauge wires, you're suppose to have a smaller fuse for each wire. HOWEVER with how short the runs are for power to your amplifiers, this isn't the biggest safety concern, and the line is still fused from the primary wire so you won't start any fires, but you do run the small risk of toasting your wires, the risk is just very minimal. Just thought I'd share

[@bigchungus-oj8zz]

Thank you for explaining this topic in a way that is easy to follow with definitive do’s and don’ts. I feel more confident for my next install of which I am preparing for now. SUB’d. Peace out..:)

[@muzzaball]

What a terrific video - thank you! That was so informative and so comprehensive - so I subscribed, what else could I do?

[@eddietrombley504]

Great video and Thx for the input! I'm actually about to install my system within the next 1-2days and Just had a couple questions... For one I'll be running two amps, one RF type x2.c which is a 200w 2channel which will be going to my rf T2 components in the front doors and that's it, and I also have an RF 1501bd mono amp pushing 1500rms @2.. So I want to run 0gau to the mono, how would you suggest running my power wire/s? Would I just run 0ga all the way down to the mono and splice in a 4ga wire to the 2channel? I have all kinds of dist. blocks and Tblocks that I can use also... And if I'm able to do that, once I splice the power wire, would I then need a Anl 150 fuse for the mono and a smaller fuse for the 2channel? Also how do you suggest running my remote wires through my system? Sry for all the question but I'm just kinda stuck, been hearing 17636862 things and not sure what's right, and I'd love the PDf you have - [e-mail]. Thx! Much Appreciated

[@juniorlopez1525]

AWESOME VIDEO AND DESCRIPTION 👍

[@connormcgee6398]

I have two batteries in my 02 f350 so should i just run one wire to each battery or do it this way?

[@sherkhan808]

Excellent video thank you kindly :)

[@fluorke]

I'm forced to put het powercord and the RCA cables on the same side. Would it be ok to put both cables in a separate sleeve to get rid of possible noice? It's active sub of 240 watt only.

[@224rebels]

So if you think anything over a 300 amp fuse is a dead short then what should I do if the three of my Rockford amps together draw 500 amps? I have each amp fused independently but I still need a 500 amp fuze within 18in of my battery on my main power wire correct?

[@Lesscoelectronics]

[@91rickstar]

You can buy anl fuse distribution blocks and I've had that same problem with the noise not a ground problem mine was RCA problem picking up interference from the altanator

Good shit bro. Very informing.

[@kaosinlondon]

Hi i have 2 x kicker L7 subs, i was looking to fit another amp for my component speakers, i dont really want to use my existing amp and connect another one to that because that amp is connected to my stereo lineout where is says subwoofer, i have 2 more places for phono leads at the back of the stereo and one say front speakers and one says rear, i am guessing the second amp connects to those but i am not sure how the connections must go.

very informative, Thanks for sharing.

[@myronwilliams262]

Another question on my eq the main source on the eq that runs a rca into my head unit is the main input that links them together I don’t have a audio output i audio input. But I just ran the rca cables from the main source of the eq into the front pre amp outputs is that the right way of doing it

[@jessicaangulo6902]

so I've got a 5000 watt planet audio amp one channel. it has the big box fuse. I think you said it was ANL fuse holders. and I don't know if I need anything else to get it running. Can you help me out?

[@SammySidhu]

Good info mate .. thanks 🙏😊

[@hofn420]

anl fuses are made up to about 650 amps in my system i use 300 amp anls if u got the wireing that matches a 300 amp fuse go ahead and use it under the hood or at ur 2nd battery to protect ur wire if ur amp hss no input fuse figure out what fuse is rated at about that level you will need in my case i got 0gauge OFC from front to back battery. Fuses are 12 inches from the front battery AND 12 inches from the back battery and for that gauge wire 300 amps is just the right size and in the back i fused the lines to my amps my 2x1000wattrms sub amp(200 amps) and my four channel(60amps)

[@Zenithity]

I'm considering running a T distribution block to run 2 amps but if the 2 amps run off 1 power wire (0 gauge) would it be too much? and wouldn't I need to run 2 separate fuses for each amp? how would I do that with 1 power wire?

[@christophervtec762]

Thank you for the knowledge 👍 I have a question I'm about to be running a 1500 watt rms amp you think 3 100 amp fuses in a fused distribution block would be enough to power that and my 600 watt 4 channel amplifier plus a 2nd battery with a 100 amp fuse under the hood using 4 gauge wire ?

[@domls1317]

Use bigger gauge wire bro.

[@padalinomichael]

I have 2 fosgate amps. 1 for my interior is about 300 watts and a 1,200 watts for my subs. I have a 5 farad cap and a .5 farad cap. Is the 5 farad cap enough for both amps, or am I better keeping both caps hooked up??

[@SuperAjay98]

I have a 2400w on my subs and 600w on my doors speakers I want to add a 3rd amp for my powerhorns on the outside side of my car or would 3 amps be too much on my 1 yellow top optima battery ?????

[@ygbodybuilder3023]

Quick question. Let's say I already have my two amps wired to the main battery thru a Distribution block. If I add a second battery could I just run that battery to the main battery. Will it still supply extra power and work correctly.

[@olegariovaldez4547]

Your are awesome, thanks!

[@TripleSplashAttack]

Very informative video! Question on fuse choice though. I recently bought a 1000watt 4 channell and a 600watt monoblock amp. To fuse both amps near the battery, would it be better to have a bigger fuse on the 4Gauge wire before the distribution block or have 2 separate AGU fuse holders holding smaller fuses for each 8 gauge wire? Does it even make a difference?

[@Lesscoelectronics]

yes, thats the right way to do it. and it does matter

hey i'm having a problem,I'm running a 600 watt 4 chanel amp for my front and rear speakers.I just bought a 2 chanel 2000 watt amp for my single solobaric L7 sub.How do I run my RCA "s the 2chanel has input and output RCAs not sure how to hook them up HELP!

[@kentj9087]

i think so...the current speaker in my car is (focal performance ps 165fx) thats the model.it says that i can bi amp the crossover to use two separate amplifiers to power the tweeter and the woofer.the problem is i have no idea how to do it.i know the basic install of amp but not like this.if you can send me a wiring diagram that would be nice,hope you can help thanks..

[@ramonsantos5404]

How do you install two amps for high and lows with head unit with one output? RCA splitter? Equalizer?

[@themeeksproject9785]

thanks for this videos and the effort....good job

[@Lesscoelectronics]

Glad you liked it!

[@Jmustan03]

What if I already tapped into my rear speakers for my subs, and I want the 4 channel amp? I saw another video demonstrating to cut all 4 speaker wires to add your converter. Run the rca's to the back then back to the head with the speaker wires to the other piece that was cutt off.

[@Lesscoelectronics]

you can use two line level converters and y split the rears to the subs and have it all.

[@scionxb2423]

i have two components speaker for front and back.as of now im using 4ch. amp to power front and back and a mono to my sub.i want to add another 4ch amp to power my rear component speaker.do you mind to send me a wiring diagrams how to wire 3 amps together?cuz i want to use my one 4ch amp to my high and mid in front and the other one 4 ch. amp to power the rear high and mid..thanks hope you can help...

[@SkyJUSTIN6]

Do I need to run fuses, after my power disturbion blocks or is the 1 near the battery engouh or should i run fuses on all 3 power cables?( 1 near battery 2 after block)

In the description

[@yan5362]

is it safe to power 3 car voice amplifier with a single power from battery?? indeed by using the appropriate power splitter. its 1 pioneer amp(8604), 1 soundigital amp(1200.4) and another amp for tweeters.

[@HSKhardStyl3011]

everytime i have a question i come back to this video and it always answers it

[@Empiretrooper86]

2 things use true to gauge ofc wireing like kicker nvx audio jl audio stuff like that and dont use a cap there juck use a xs power battery

[@roach_d21]

If I have a second battery, can I run a power line from it to a mono amp and another to a 4 channel amp like you mentioned doing with the capacitor?

[@Lesscoelectronics]

Sure, you can alwyas run batteries in parallel like that.Just make sure you have them fused independently.

[@BlaqspeedAudio]

Great video for beginners, but the one thing that is wrong, is that anytime you are wiring two or more amps, or adding signal processors, it is always advisable to use a relay on the remote turn on wire, as most remote turn leads do NOT supply enough amperage to turn on multiple components, and the head unit remote output can be damaged by the excessive current draw. The maximum output current is usually never listed by any radio manufacturers, neither is the current draw listed by amp manufacturers. Just trying to help save people from un necessary head unit repairs.

[@gantzthegreat8998]

I have been running five amps with my head unit for five years and always have done so before....so theres that!

[@bigchungus-oj8zz]

Great point, my friend. TY for the heads up.

[@ygbodybuilder3023]

Help me out with this. I'm running two amps one 500 watts(80amps) the other 1200 watts(100 amps). I'll be running a power wire from the battery to a Distribution Block with 4gaughr and 8gaue. At that distribution block I will have a fuse of 80 and 100. At the fuse at the batter I'll have a amp of 200. Does this look correct.

[@thegeneraljoe67]

Great information. How can i obtain your free PDF ? Thanx for posting this video.

[@robertehlers4330]

So ground noise dont use isolater just seperate grounds in diff. Spots?

[@TheRealDJOsk]

Hi, checked out the video because I'm trying to figure out, what gauge wire should i use for two amps. The subwoofer amp is asking for a 4 to 6 gauge depending on the lenght, plus I have a 4 ch for the insides, that. Also needs a 4 gauge wire (according to the manual). What do you g think?

[@Lesscoelectronics]

TheRealDJOsk get 2 gauge and break it down where the amps are mounted, that will be sufficient I believe

[@MrAhmed1602]

Hello, I learned a lot of things in this video. I just had one question, can I put two capacitors?, one for each amp. I was thinking of putting a power distribution block with ANL fuses for powering up my 2 amps, starting with a 0 gauge wire and then distributing it in 2 of 4 gauge wires. My 2 ANL fuses, one will be 50 AMP and one will be a 25 AMP, because my 4 channel amp has a 50 amp fuse and my 2 channel uses a 25 amp fuse. So is it okay to power distribute each amp with its own capacitor. And as you said, I will also ground each amp alone in separate places and to far from each other by at least 1-2 feet.

[@Lesscoelectronics]

Ahmed Hassan Sure,you can use as many caps as you like.

[@jasonlopez4855]

Good video 📹👍🏽

[@Lesscoelectronics]

Thanks 💯

[@mikethayer2698]

When using a larger feed line that goes into a smaller gauge output, you should always have it fused.

[@danielmejia5888]

I have a question if i use a digital top post do i still need to use the fuse holder?

[@michaelpalmisano6788]

Daniel Mejia yes. The fuse is there to protect the wires and the components the wires connected to in the case of a short . In the event your wire gets to hot or shorts out the fuse will break stopping the current flow to the components . Always always always use fuses. The top post terminals he's showing in this video are just other options you have to the distribution blocks. Basically all those top terminals are are distribution blocks , nothing more nothing less.

[@andrewrosado7179]

Question if a capacitor has been unmounted and want to mount it again do you have to recharge it

[@nicholasram8235]

question, right now I have a single 4 channel amp(400rms) playing mid/ hights on chnl 1 and 2 and chnl 3/4 are bridged for sub,, I'm plannin on putting another amp in to the sub but my question is about the power, I have a round fuse holder as you have in the video with a 60 amp fuse for the amp currently then that goes from 4g into a T block as you have also and an 8g from one output of the block to the amp, the amp is fused with a 30amp fuse... the second amp I want to put in is a crunch ds400 which also has a 30 amp fuse I think, but my worry is with the main fuse and fuse block, can I use the unused connection from the T block to power the amp for sub? If yes do I have to upgrade the main fuse holder rating or can it stay at 60amps... alsssoooo do I instead have to buy a fuse block with one in and multiple fuses out?.. I hurried to ask this question and if anyone can help please it will be greatly appreciated, you an even email me or contact me anything, I just dont want to make any mistakes and cause a fire or blow my amp/s even tho they have replacenable fuses

[@thomascollins7131]

This was incredibly helpful. But I still need help. Soooo, I am gutting and remodeling a 32 foot 1988 RV into a mobile tailgating party lounge here in Arizona. I was going to put in two amps 800 and 550watts for speaker and the subs, respectively. Now I am thinking I need the 800 for the subs, is this right? I am putting in 4-6 10 inch subs (Cervin Vega and JBL) . Definitely going with Fosgate amps now that you described them here. How many speakers can I put in this thing? 8? 12? I have no clue on how to achieve the best sound. Can you help me in the design process? Some speaker are going up high where the cabiinets use to be. Others are going down low in the built in seat (fronts), the subs are also going in below the seats

[@kentj9087]

how can i wire a 4ch. amp into two front left and right tweeter and two left and right mid woofer? thanks

[@Lesscoelectronics]

I assume youre using a passive 2 way crossover network with them, right?

[@jdrobertson76]

My question is, if you run one 0 gauge wire from the battery to a distributor block and two 4 gauge wires out, would it still be a 4 gauge setup to the two amps? Also I would like a copy of your PDFs file pls

[@Lesscoelectronics]

+jdrobertson76 if the main leg is 0 and the amp only takes up to a 4 ga input. that would still be a 0ga run. if the amp takes 0ga in, get a 0ga distribution block to maintain that integrity. I hope that made sense!

[@jessejames6687]

I agree with u , but getting a decent amp install kit for 50 or 60 bucks at most is a lot cheaper

[@koreycantrell6813]

Do I need a dual fuse when hooking up 2 amps?

[@Lesscoelectronics]

You should always independantly fuse your amps, even if its an internal fuse on the amp, but each needs at least 1 - but preferrabley 2 one at either end of the power source

[@bionikcruz5977]

I think I need a cap, my subs and mids keep turning off. Got 4 gauge wire and ground and it's all hooked up well. I mean I only have 600watts total. Trying to get an upgrade alternator on and Honda Fit. But I won't know till I get a cap. I will keep posting if that fixed the problem.

[@mcfriedchicken1972]

Ok so I have two Alpine amps I want to install, the MRV f300 and MRV M500 and both have set screw terminals. One takes 4 gauge and the other 8 gauge only. Is it ideal to run 4 gauge for the main power into a power distribution block and run out one 4 gauge and the other 8 gauge for each amp? Or should both wires be the same gauge? Same for ground

[@mcfriedchicken1972]

By set screw terminals, I mean those terminals that take wire ferrules

[@Lesscoelectronics]

You should give the amp the largest gauge input that it calls for in the specifications. or as close as possible anyways...

[@NEONGR86]

That black and red breaker that has a button which way should the arm part be facing it to be working?

[@Lesscoelectronics]

+bobman123googoo it should be at a 90 degree angle, if its at a 45 that means the breaker is open

[@NEONGR86]

+Lessco Electronics So if it's facing the button then it's on but if it's facing away front the button then it's off?

[@Lesscoelectronics]

closer to the button is on

[@ROTORHEADPR]

how do i use the capacitor as a distribution box .thanks

[@joshua199628]

just hook up the power wires you want on it and send them to different amps or something

[@alexalejandro1399]

Was wonder what I would need to use if I wanted to hook up my stock oem head unit with 2 amps one for highs and other for sub...would I need an equalizer

[@Lesscoelectronics]

an eq would definitely simplify it

[@rsr3245]

Lessco Electronics what if I can't get an eq. What could I do in that case?

[@LumenChaser]

Ruben Santillana use the rca output in the back of the head unit to the input of the amp, and if you don't have any you would need to install a inline converter
