Alright I went out and got the Alpine IDA-x001 digital media receiver. I neglected to buy the factory wiring harness adapter but I do have the Alpine specific harness that plugs into the back of the head unit. I was just going to match wires and crimp.
Furthermore on the the12volt.com I located a guide to the factory colored wires behind the head unit. However, I've tried matching the labeled ones on the Alpine harness to the ones in the dash and no sound. There are also some wires which don't seem to be used at all which leads me to believe there is a factory amp. I have a 99 tahoe 4door. The front two speakers are components and the rest are coaxial. I have no use for the 4x10s or whatever in the trunk. No onstar or anything. Someone please help.
