hey can you hook up 2 amps (one for front speakers and one for back speakers) to another amp for a sub? how with like an RCA that has 4 prongs on one end and 2 on the other

Well if your talking about bi-amping, you dont want to do it unless you have two identical amps. But i dont really understand what you are saying

ok how would you run an amp and a sub when there is an amp powering 2 fronts and an amp power 2 rear speakers and the deck only has one output or would it even be possible

Simple. just get some RCA splitters. If your deck only has one set of pre-outs i'd imagine you already used some RCA splitters to power 2 amps.

ya i got how you could wire up the two amps to the deck but how would i add on a subwoofer and a sub amo to the setup

Ahhhh....this is a bit easier to reply to than your original post.

Running two amps off of a single RCA preout is fairly simple. If one amp or the other has RCA outputs on it just run the 2nd amp off of the 1st one.

If there are no outputs on either amp just get some RCA Y-splitters and feed both amps from the same source.

front amp rca rear amp rca ?sub amp?

is that what you mean

those are all connected fron inputs to outputs obviously from one to the other

You can do that too. or just do Front-Sub AND Rear or Front-Rear-Sub.

goddamit each of those boxes r amps the comp ****ed it up when i posted it

 

[pablo4429 10+ year member]

sp all the hi-pass and low-pass filters would still work?

They should.

A line driver or an equalizer will allow you to take the pair of pre outs on the back of your deck and split them into front/rear/sub outputs with out any voltage loss.

The other option is to use an rca splitter to split the signal to your seperate amps, you will suffer some voltage loss though from your headunit meaning a graeter chance of noise in the system and a need to turn the gains up higher on your amp.

Some amps have a "pass through" built in that allows you to daisy chain seperate amps off of one line, it will appear as as an output beside the input on the amp.

 

[pablo4429 10+ year member]

if an amp doesnt have a "passthrough" can you still use the output terminals to daisy chain them

 

[Beat_Dominator 5,000+ posts]

Should work, depends on how it sends the signal throught the Outs.

sorry for all the questions i got confused when i treied to figure out if it would be better to use two amps or one 4 channel but is there any way of knowing beforehand if it would work. i had no idea it would be so involved
