Well I found out her car already has 4 gauge wires for the power and ground right now. So all I need is a distribution block and I have some 6 gauge wire I am going to use to go from the block to the amps. I have far more important things to deal with right now though. Her car needs a new water pump and its not like on 7s. She has an MX6 and they got those sideways engines

 

Oh, one more thing about the stereo stuff. How do I run the RCA cables? Is there something where I can split off of the ones I already have hooked up? I am going to need 3 sets(2 for the 4 channel amp and one for the 2 channel) and I believe the cd player only has 2 anyways.

 

The ideal way would be to use a EQ or X over (both will be even better), both have one input (at least) and two outputs (at least). If $$$ is an issue, get two female to male Y connectors (one female = Input and two males output), use them on your 4 ch amp.

BTW - No need to use a 6G cable from the junction block to the amps. 8G should be more than enough, unless otherwise stated on the charts. Besids 6G is not a common gauge on car audio.

 

Well I am going to go the route of using the y-split RCA wires.

The reason I was going to use 6G wire to the amps is because thats what I have, I used it in my old car. Thanks for all the help.

 

Ryde,
How many outputs are on your stereo for RCAs? If you have more than one you best bet would be to run more RCAs from the headunit to give you more control over the speakers. You next option would be to get a crossover, and set all of the settings on it, and have your 3 RCAs come out of it, and the third option would be to split the one RCA three times, and set the crossover on the amp.

The block is in bery good condition, only used for a few months. I found out the block is made by StreetWires.
I seem to have misplaced mine, but ill dig aound for it tomorrow when its warmer. Heres a pictire of it off their site:
