2 outputs (head deck) 4 inputs(amp)

[mad_dog]

Hey guys, I have a 4 channel amp, but my head deck has only 2 RCA outputs, is it possible to connect the head deck to all 4 channels and not just 2.??

You will need to connect 4 inputs, to get 4 outputs. So you'll need some RCA splitters. You will need 2 splitters, so you will end up with 2 left, and 2 right inputs (at the moment you will only have 1 left, and 1 right). Then 2 sets of RCA leads, connect them to the 4 inputs on the amp, then your good to go.

Ok thanx for your help mate. ;-).

err... I dont understand why a splitter is needed? Doesn't 4 channel mean it can power 4 speakers? 2 fronts, 2 rears.. the RCA's will be; one for fronts, and one for rears.

I don't think any splitter is needed...

Denno you're thinking pairs, he only has a single pair of outputs, so he needs 'Y' adapters/splitters.

[Ray De Man]

I don't understand correctly either.... Doesn't he mean he has two outputs from headunit (a pair) going to amps input. The other two on the amp should be a pair of outputs to go to another amp (daisy chain). With a pair of inputs into amp he can run two pairs of speakers as it's a 4ch amp. Unless he is planning to run more then one amp then he'll need 'Y' splitters or just daisy chain amps.

4ch amps have 4 inputs (front/rear - left/right) If it only had 2 you wouldn't have fade and/or balance controls

As the headunit only has one pair of RCA's which are usually rear or sub output, if you plan to run front speakers you wont have fade controls if you use RCA splitters.

My mistake, I was thinking of mono amps for some reason, I forgot 4ch amps have two sets....
Won't it be easier just to buy another headunit that has more then one set of RCA's? Or saying that, in my brothers car he has a crossover junction box as he has the VE SV6 and the stereo is built in to dash. He has front and rear fade.

Then he would be spending $150 +, plus when all he needs to do is split this RCA lead, to get another 2 inputs. Unless OP has big plans for the stereo, with additional amplifiers, ect, then there's no need to upgrade his existing unit..

Hey guys to help clarify I have 1 red and 1 white out put on myhead deck, and 2 white and 2 red inputs on my amp, so tomorrow I'm goin to get 2 splitters one for red and one for white so I can run all 4 channels.
Sorry bout any confusion.
Thanx every1 for their input.

Too easy mad dog, just use your gains to bring the front speakers slightly louder and you'll be in business.
Play a song you know well, close your eyes, you want to hear them as if they're coming from an imaginary stage on your bonnet. (Of course this varies from person to person as to what sounds good) But it's usually a good measuring stick.

[mad_dog]

Hey I put in the splitters today and connected another set of speakers, it sounds GREAT,
I put the splitters at the amplifier end, and I'm using 1 RCA cord, does that matter?

[HCVP]

The way you've done it you should have lost your fader adjustment. I'd be splitting at the output on the head unit, then running 2 set's of RCA's to your amplifier.

It would be the same

[holdenboy]

Exactly, and he'll need two sets of 5m RCA cables, not to mention 1 male to 2 female splitters.

As an alternative which allows fading is the item below.....you will need 2x RCA 5m cables though (if mounted on the dash).

now im confused lol..So they way he has it now will be alright?

[mad_dog]

Yer, the way I have it now will be fine from what I can gather, only I won't have any fader controls. Unless I get a splitter with a fader control built in:-)

[holdenboy]

Yep the way youve got it now is fine.
