That's where you're gonna have to get creative...there's no real "instructions" for aftermarket stereo installs.

I had to drill 2 holes in the firewall to pass my 0awg pos. and neg. cables to the trunk. Installed the amps upside down (2 phoenix xenons) under the rear tray.

There are already wires passed in the wiring harness if you don't want to run after market rca's, but i can't remember what the pinout is for the hook-up at the amp in the trunk...

On that note, the system is amplified already, so be sure you know what you're doing. It's not a simple cut and paste job.
