Question about 2006 Chevrolet Trailblazer Ext
The front speakers plays but I fade the radio to the rear speakers only there is no sound
The most common solution is both rear speakers are bad. Not what you expect, but is what we usually find. could be a driver in the radio.
Go back to the rear speaker and put your ear right on the speaker and notice if there is a faint sound.
Have a test speaker and plug up before you buy the correct ones.

Look on ebay, craigslist, and check local junk yards, nka auto recycling centers, and you will find many plain jane stock GM radios for sale cheap. i would stay away from the high end units as then you will be on here asking for instructions on how to reset the anti-theft codes.

check wiring on passengers side near the rear hatch speaker, the rear door speakers are run through them also. i had the same problem and it was a unplugged connector at that location
