Working with this amp: http://www.crutchfield.com/p_113KAC8...-KAC-8406.html
Head unit is hooked up with GMOS-04.
Im gunna split it 2 channels for the sub bridged, then 1 for each 6.5" in the doors for 4 channels total.
The sub and door speakers I dont have any confusion with because Im running RCA's right from the head unit to the amp, then speaker wire from the amp to the sub/doors.
Im a little unsure about how to handle the rear deck speakers, the tweeters in the doors, and the center dash speaker. I assume that all the speakers in the car get their power from the amp, so when I chop the amp out, those speakers wont get power since the new amp wont be hooked up to them. Do I need to chop up the wires connected to the factory amp and splice into them to run new wires to those speakers not powered by the new amp?
I was also wondering about the remote amp turn on wire, can I take that from the factory amp wires, or do have to take that from the harness at the head unit?
