How To Run 2 Amps?

[TurboEx]

How exaclty do you run 2 amps? Im looking at my amps and headunit and just cant figure it out. Obviously the power/ground go to the battery and a ground for both. But I dont get a few things.

Im looking to run 2 12's and a 1 amp for each sub. I just dont get how it can work.

Like the rcas, isnt there only one spot for a right and left RCA for one amp on the back of the headunit? Where will the second rcas.
At first I thought the first amp goes to the back of the headunit and the second set of rcas goes form the second amp into the amp running the the headunit already, but the amp alos only has one rca imput.

Remote- wtf does the remote do? is it a ground or does it go back into the headunit? How will both be done for both?

AS you can tell this is my first system.

HU is a Blaupunkt cd50, I know its shit or cheap or whatever but it matches some misc interior and was practically free (12 pack Hein)

Thanks and I hope you can answer my questions

well i like to bitch alot, and this has been gone over about 321455mill times but im in a damn good mood so hear we go. maybe i should write this out and get pics and sticky it.

1) you have a power wire coming off your battery. since you say you want to run 2 amps, i dont care the size. you best have nothing less then 4 gauge. second you do not get your ground from the battery. you make a ground nomore then 3ft away from your amps.

2) you will need what people liek to refer to as distribution blocks. breaks up the power. you will want to get one w/ a 4 gauge in and 3 8 gauge out, i prefer a 4 gauge in and 4 gauge out but these blocks are usually alittle harder to find.

3) all headunits only have one rear output, some have nonfading/sub but all amp only have one preout for subs. so since you stated that your amp doesnt have an input and an output just an input you will need to split you rca. this is done w/ spliters. a spliter with 1 female and 2 male ends. this is bad b/c it cut your preout volts even lower. and w/ your deck you probally already have a low preout voltage.

thats it you will also need a distribution block for ground. its best to keep one ground, then there is less chance of picking up engine noise.

also on the remote this is what turns your amps on. there should be a remote wire off of the back of your headunit already, if not the remote wire can be tapped into a red wire on aftermarket wiring harnesses.



i can answer any question you got! :lol:

Sorry, search doesnt work for me and I didnt even think there would be a thread like this.

OK I get the remote part, just wasnt sure on it and I do have the output on the back on my HU and I just splice the second into it right?

Also, I worded it wrong, I wasnt going to ground it from the battery. My cars gutted so I can practically ground it less than foot from the amp on a nice clean surface.

Im really not getting the dist block thought know matter how many times I read your post. I have a lot of 4ga wire so thats no problem. I think I know what you mean but do you have a diagram or something that show some easy to understand stuff on how the dist block is wired with 2 subs and 2 amps.

Thanks for the quick reply, should have my system going I hope by next weekend. Just put my huge alt and yellow top in yesterday (paid 200 for the pair new)

Thanks again

ditribution block there many diffrent ones

out out
<----out out----- > in===out
in out



and all you need is (2) 2male, one female adapters

Im sorry I didnt get that "out out" keyboard diagram so I wasted some time and made a rough diagram for what Im getting so far of this power wire hookup. Ive went form being a complete audio noob a few days ago and thsi weekdn every morning til lunch I read for about 3 hours and learned so fucking much on honda-tech and here.

Dunno what you mean my male/female connectors

WOW! Getting paid 13.45/hour to watch an old people building and learning the basics of car audio while eating Krispy Kream > ***

you can also try another way to hook up the RCA's.. if your amps have a "through put" rca outs, you can run a short RCA cable from them, to the input on another amp.

yeah.. 12 ga will work in most applications.. and keep your ground wire less than 18" long.

[TurboEx]

So I actually got it right with my power wire diagram? Its just one input and 2 outputs?

How much are these blocks and does it matter how close I place it near the 2 amps? Wow I didnt think I would get it right, thats pretty easy if thats right.

And ya Ill have my ground no more than 8-12" from my amps

[speedster]

if i read correctly he state dhe only has inputs on his amp, i may be just thinking this i talk to so many people per day over audio that i could have dreamt that. and ya ur drawing is right on, you will want to get a distribution for your ground also. they range from 4-8bucks ea. and the distance doesnt matter just dont get it a mile away from them.


males on rcas have the pointy thing on them kind aliek a penis
female is what you plug it into kind liek a pussy. females are found on the headunit and amplifiers.

[TurboEx]

OK thats cool then but why would I need a d-block for my ground??

I cant just ground both of them straight off the amp onto 2 different grounding spots?

[Mac2118]

you don't need a D block for your ground.. it makes it look nicer though

try to ground everything to the same spot. If you don't, it increases chances of ground loop problems where you have feedback into the amp, excess noise, yadda yadda yadda

hmm.. what's a pussy look like? hahaha

[TurboEx]

hmm.. what's a pussy look like? hahaha

AHAHA WHAT!?

Thanks for the info though guys, had an answer everytime I logged in. Honda-Tech has like 6 times more members but I havent gotten one post from anyone that taught anything. There all calling me a newb audio installer kind of posts. Glad you guys are here

[speedster]

id recomed a distribution block for your ground, rids almos any possibility for a noise problem. just make sur ethe grounding spot is very very clean

[TurboEx]

Ya I might as well eh, whats another couple bux.

Whats this noise problem Ive been hearing a lot about on this site. Never heard of it before.

Is it from power coming back into my amp or something? What does it sound like

[speedster]

ground loop, basically engine noise. has a high piched sound and windsup and down w/ the rpm of the engine

[Mac2118]

There all calling me a newb audio installer kind of posts.

I always get thaqt stuff except over in the performance section.. they love to make fun of me there.. so that's why I don't leave the audio section..

[speedster]

i called you a newb in the performance section hahahahahaha u dumb newb :D

[Mac2118]

yeah.. I am too.. like my sig says.. performance? what's that?

haha.. I love car audio.. the only performance I need to know is about the electrical system.. and that doesn't take much..

[TurboEx]

I started off as a performance junky on a budget. Only 17 so I bought a sohc zc with i/h/e/gutted cat and gutted rear. Was having fun to many close calls and a few close chases from cops. SO I decided Im going to make more of a show car but Im still well into performance. Putting my car on the bottle very soon, gotta make up for all the extra weight with 75 extra ponies lol

thanks again
