i have a 2000 z71 (old body style). the factory radio's speed controlled volume was all messed up and it also cut in and out. i replaced the factory radio with a new panasonic aftermarket deal. works great everything is fine.

i put in 6x9's where the old 4x10's used to be above the barn doors, along with new component speakers in the front doors using the existing factory wiring. they all work great.

i tried to do the same exact thing for the rear doors. i cut the factory clip that attached to the speakers, and wired them directly to the new after market speakers. there's NO sound. the stock speakers worked before, even after i installed the head unit and other speakers. i talked to some guy that thinks he knows about car audio, and he tells me there is an amp turn on wire that needs to be powered for the rear speakers. this sounds wrong. i dont understand because there were 2 wires going to the factory speaker, and the same two wires (+ and -) are going to the new aftermarket speakers. i've tried + to +, - to - AND + to -, - to +. i'm pulling my hair out over here trying to fix this.
