What kind of system do you have? It is possible that you have lost the amp.

Yes its all the way up. The rear speakers dont work at all. The front tweeters are the only thing that works.

Radio swap didnt work... I had the same problems. Swapped for an aftermarket radio, purchased the correct connector and the sound from the speakers is the same as it was. As far as I know the OEM radio is not a Bose system, it doesn't say Bose anywhere on the radio or dash....Just a regular am fm cd player

I have a 07 trailblazer as well with the same issue. The front speakers work only. I checked the fuse and its good. Trying to narrow it down to the stereo itself or the amp (which i'm not sure where its at. I think its under the back seat with in the fuse block??? I will come back if I figure it out.
