Hey guys. 07 Tahoe with stock radio. Having speaker issues, maybe you guys can help me get to bottom of this. Speakers work intermittently. Front left always works, and the rest of the speakers rarely work. Every 20 trips or so, all the speakers will work. Sometimes while driving they will all pop to life, but for the majority, just the one front speaker, with zero bass. No rhyme or reason.

I have considered replacing the radio, but what do you guys think? Is there a more appropriate place to post this issue? Thanks gents!

 

Most likely the speakers are bad. remove the door panel and inop speaker connect a test speaker to see if there is power.

 

Do you have the Rear Seat Entertainment RSE? if so often times reseating the connections to the rear control will resolve some issues...
