Hi, I just bought an 05 sp23 with Bose, but neither the speaker or tweeter in the driver's door work. Does anyone have any idea what could be wrong? Is it wiring, or amp/head unit problem? I tried pushing it a little, incase it's the relay in the door, but nothing. Also, is the subwoofer under drivers seat also, cos I suspect that may not work either. Both rear speakers are ok(not great sound) but the only useful one right now is the passenger door one. Help please.
I would start checking all the wires to the speakers. Which means pulling the door panels.
