Hello, my surround sound suddenly stopped working. I feel nor hear any bass. I never touched my equalizer since I had the car for 3 years. The front speakers work but the left rear speaker isn't producing sound only the right rear and front of the vehicle speakers. I don't even want to drive the car anymore until I get it fixed. What could be the problem? And it isn't Harmon Kardon surround sound brand either. I'm assuming it's basic. I even went into setting and turned the bass all the way up and I still don't feel or hear any bass from the vehicle. What should I do? I don't have patience for 1-5 weeks repairs I need ideally 1-3 hour fix. Any one experience this problem before? I must add that my car was in impound for over 6 weeks just got it back yesterday.

The floor subs or the door speaker?

if you want a quick fix start with inspection of the subs under seats. if impounded maybe someone removed them. trust me lots of things go missing when car in impound lots. plus if there are. that would be reason why not hearing lows from other speakers. i am not expert but just throwing out ideas for a quick MPC(MostProbableCause)
the other thing is disconnect battery and leave lights on.(so drain power from system completely) and then reconnect, this might reset your oem amp. sometime that would work when i lost sound to my E38 but on that occasion i lost all sound, worth the inspection.

just an update for future reference. althought it sounded like the sub were making noise during the test phase they weren't. replaced both subs with used ones and its working again
