I have a 2007 chevrolet trailblazer, my car speakers don't have any base and have a high pitch. I recently replaced them with factory speakers off of another trailblazer and they still don't woRk.
Sound,s like it may be the stereo is bad not the speakers,do you have the bass setting all the way up ?
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.
Not sure about the system. Its a factory stereo
Here's a Bose
Its not a bose
If rear speaker,s are not working it will be the preamp,built in to the stereo
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
Trlblzr manual eom radio has listed that they use a bose system (I was surprised to with no bose label)... Did u get to figure out your radio problem? I bought a 2007 and the radio and speakers (front speakers play but with no bass sound and back speakers are not playing at all)....any help would be greatly appreciated.
NO ONE HAS AN ANSWER
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.
