Question about 2002 Chevrolet TrailBlazer

1 Answer

My 2002 Chev Trailblazer, the 2 rear speakers are not working. I know they are linked to the rear seat stereo and when this is on it is supposed to shut down the rear speakers but the rear seat stereo is not on and I still have no sound out of my rear speakers?? Is there some reset button or some button or something I am not aware of that would be a quick easy fix for this problem? Everything else works fine(front & door speakers).

Sounds to me as if you may have a short in the speaker wires or they may not be hooked up at all. follow from back of stereo follow wires all the way to rear speakers making sure that they are not showing any bare spots.

Rear speakers stopped working


my speakers went out front and rear i was told by an audio tech. that the systems that chevrolet put in them each speaker has its own amp to bust the sound the only way to fix it is to replace them.
if you have a warranty chevrolet will replace them otherwise find a junk yard or new system. i ordered a set of used speakers off ebay havent installed yet.
