Rear door speakers don't work w/ aftermarket radio in 94 suburban

\015 How do you make the rear door speakers work with an aftermarket radio in a 94 chevy suburban\015 Posted / edited by AnonymousUser on : 25-10-2021

Answers :

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.
