02 Tahoe replacement radio issues

[donmauldin]

I have replaced my oem radio. The front door speakers works fine.
The rear sub and rear door speakers doesn't work.
I have replaced the subwoofer, and the rear radio controls and of course the radio. Double checked the wiring, got the amp turn on connected.

Can i disconnect the wiring under the console going to the rear controls and connect a speaker there to eliminate any rear wiring issues?

How do I trouble shoot this?

Check the power wire and remote turn on wire for the rear amp for power at correct times.Check same for head unit.
If the old radio worked, then it is something you did.

The rear door speakers and sub stopped working with the original radio I replaced the sub and it still didn't work so I assumed it was the radio I put a new radio in and the turn on wire is wired and the sub still don't work I do have power going to the amplifier but I straight-wired a speaker from the terminals on the a mp and still didn't get any sound

So then the amp is bad.

Did you replace the door speakers or not yet. I would suggest doing the jumper harness to delete the factory amp entirely. Then run your own amp to the factory sub, the rear pillar speakers won't work unless you run a lead from the rear door speakers.
