to put two amps in yr car do u need two sets of amp wiring kits? and how do u connect ball 4 rca plugs in bak of head unit, any other tips on this would be great

Not necessarilly...depends on the kit you purchase as you can get multi-amp wiring kits - just have to shop around.

Yes you will need 2 of everything....you may want to run the amp power and ground connections to common points to save on cable etc tho...so need to work out your needs depending on how you plan to install and wire this system up to which kit will suit you best.

Rockford fosgate offer some pretty neat levels of packages for multi-amp installs...

To connect multiple amps to your head unit all that is required is to split the remote line to both amps (so both amps turn on when the head unit is powered on) and as to RCAs it depends on the purpose of the amps.

Will the amps be setup as say a 4 channel for speakers and mono block for subs....etc

Do you know how many Pre-Outs (RCA) outs your head unit has or the one you are enquiring into this about...? Make sure you check they are RCA outs for signal channels and not your red/white auxiallarys....

oh ok thanks man great help

No problems dude give me a yell if you need to know anything else...
