    Hi Mike,

    Aftermarket what? I'm going on guesswork here.

    What is the problem?
    Knowing what wires from the radio go to the speakers?
    Finding the wires from the speakers to hook to the radio?
    Something else?

    Let me know

You need to attach the blue wire on the stereo harness to the blue and white wire on the car adapter harness. they installed a small amplifier to power the rear door speakers and unless you connect those two wires then the speakers will not work.

I had the problem on my 94 Suburban. I hooked a new stereo head -everything worked fine, including the rear door speakers and the back upper deck speakers (6 speaker system). I then installed a sub woofer and amp. I cut the blue wire from the new harness, which was identified as antenna wire, to use for secondary circuit for the new amp. Guess what! the rear door speakers stopped working. tjgdjn is right! When I reconnected the blue wire from the new harness to the plug which connected with the orginal harness, the rear door speakers worked -again.

Am I correct in Saying that those are the Only Rear Speakers? You can always do what I did for my Dads Suburban. Built the System, Mounted 6x9's under rear seats then Cut and Mounted 15' Woofers in the Back Doors! MAN it ROCKED! If not just hook up to the Rear Outs on the Aftermarket System.

Did it fail while you had vehicle, or like this when you bought it? Could be bad radio or wiring harness was chopped up when previous owners had an aftermarket radio installed. They probably just slapped the OEM radio back in when selling car. And didn't put all the OEM wiring back in.

2000 Chevy Suburban radio not working

Sounds like an internal problem with the radio. There are places that repair factor radios, but for the money, you are better off buying an aftermarket radio. There is a company called Scoche (spelling) that sells a good line of wiring adapters and mounts for aftermarket radios so you can install them yourself. You can get a good radio (some with the new HD radio) and CD player for under $150. The mount kits run about $15 and the wiring harness runs about $10....all abailable at Best Buy or Wal Mart
