Radio Dead or Amp Dead
 

Hey Guys,
This morning when I got in my 04 z71 Avy my Bose 6 disk with XM had no sound. I am not even getting the beeping noise from leaving the keys in the ignition or head lights on. If I turn the rear seat controls on, I can listen to the passenger side jack with my ear buds. Do you think it is the amp or head unit. Thanks for any help.

I bet the problem is the amp if you're getting sound from the rear headphone jack.

It might just be a blown fuse.

Good luck.
