My Alpine deck has three pre-outs, one pair front, one pair rear, one pair sub. I have two 4 channel amps. How do I get a signal to all inputs? Do I use these?

Deck: Alpine CDA-9813
Amp 1: Soundstream Rubicon RUB600-4. 4x80 watts @ 4 ohms
Amp 2: Elemental Designs NINe.4. 4x65 watts @ 4 ohms
Rear Door Speakers: JL Audio 6W0 4 ohm. I plan to run these in stereo due to the fact they only handle 75 Watts each. I will run these off the Soundstream Amp.
Sub: JL Audio 10W0-4 in a bandpass box. I plan to bridge the other two channels on the Soundstream amp.
Front doors: Polk components. I will run these with the ED amp.
Front Kick panels: Soundstream Exact 5.2. ED amp.

 

yes that is what you use to split the signals.

 

Why not use 2 of the preout and run 2 sets of RCA's? Thats the proper way of doing it, the 3rd preset is for a subwoofer!

 

run channel 1(front) from the front to the nine.4(great amp love em) channel 2 (rear) 2 the amp channels for the rears and the sub to sub channel of the amp. then you can still fade the speakers and use the xover in the hu

 

Sorry if I left that part out, I have 3 RCA cables running to the amps.

 

That is what I was planning on doing. Do I have to split the RCA for the sub to have inputs for all 4 channels on the Soundstream amp? Or does the amp have an option to run all 4 channels from one RCA input?

 

no you need to run 2 seperate rcas to it. as i the wiring ways for a 4 channel is 4 channels 3 channels or 2 channels. not mono. you want are wanting to run the nine.4 as a 2 channel. and the soundstream as a 3 channel so the jl's are your midbass on channel 1 and 2 and channel 3 is run the the jl 10w0. thats the only way you can wire it. thats is how i have always wired that kind of setup.
