Well theres 2 things wrong with my stereo, one the Bose cd player on the HU is not working, it wont even take a cd. And two, the front left speaker makes this high pitch noise thats ****** annoying. Either i listen to the radio real loud to drown it out, or i cant listen to it at all. Someone told me before its prolly the capacitators on the front amp? how do i go aout fixing that. And does anyone know whats up with my cd player?
