i am in the process of building a system to install into my car...
any input would be greatly appreciated.... as in what am i missing are there any specific wires that need to be hooked up in different spots then just behind the dash for the new headunit (i have the standard GM harness plug that came with my Alpine headunit from crutchfield).

Here is what i have or am going to get:
car: 2003 Z06
Crazy Cowboy sound/heat deadening
Front Speakers: MB Quart 6.5" Components QSD 216
Rear Speakers: MB Quart 5.25" Coaxs DKG 113
Amp for speakers: JL Audio 300/4
Subwoofer: JL Audio 10W6V2
Sub box: hangover hopefully from NVTHIS
Amp for subwoofer: JL Audio 500/1
Headunit: Alpine CDA-9886 (with ipod controller)
Wiring/interconnects: all Tsunami/Ausiopipe/Monster Cable

I will be ripping everything out of the car and hopefully only plan to install all of this once.

So any pointers/help/hints would be greatly appreciated.

Thanks to everyone!!!

Rick
