All of my front speakers stopped working, including

Customer Question

All of my front speakers stopped working, including tweeters. Also, my chimes and onstar no longer work. I do have the bose system. I am just not sure if it would be the amp or radio. Everything is stock.
JA: Have you checked the fuse?
Customer: Fuses have been checked. The rear speakers work perfect, just not the front.
JA: What is the model/year of your GMC?
Customer: 07 sierra. New body
JA: Are you fixing your Sierra yourself? What have you tried so far?
Customer: Thats correct. I have tested all front speaker and all are in working order. Checked the fuses, as well as pulled the factory amp and harness to inspect for any signs of a problem. Pulled the radio and did the the same. Im just trying to figure out if it would be that the amp has the front channels missing or the radio.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I believe that would be all.

Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner till early morning.

Normally this is the amp to blame. There is a TSB to check the amp connections to see if any are loose. If they are fine then follow these steps.

  3. Do you still need help? Please reply I want you to get equal to or more than what you paid for.
