I just bought my sc4 today and i played a bass test cd, plus just listened to the radio loud to check out the stereo and found a few things... it has very nice stock bass. umm..lets see, the thing i was worryin about was that u know the three speakers across the back?, well only the one on the driver side was playin it sounded like. the other two made no distorted noise, they were silent. this makes me wonder if they are disconnected? im certainly no expert so id really appreciate the help. oh, and where is the subwoofer?
thanks

 

You'll need to open it up and inspect. Also inspect the connectors that connect into your amp. You may also need schematics and a meter to check wiring continuity. We can't help you very much remotely. Once you get the door apart you can remove the speaker and check it with another audio source. Process of elimination.
