Ok, I'm kind of hoping it's a simple ant. wire coming off of the unit and needs to be plugged back in, but here's my situation. I have a '92 SC300 with factory stereo minus cd changer. Actually I have to SC300's, but that's for later. It plays tapes well...for a tape player...but the fm stereo rarely works properly. When it does start to pick up, I get a lot of low thumping from the factory sub, and even the larger factory front speakers begin to thump. On rare occasions, I can turn the stereo on and it's playing, but it's like it's not getting a full signal. I just want to try to avoid any unneccesary center console disassembly if at all possible. I don't mind doing it one...even twice...but if I can get others experience to know what the problem could be, it'd be helpful.
