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

Here's standard

With /EQ

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
