Something is wrong with my audio system in my car, the mid turns on and off, but the bass ia always there, have two seperate amps, 1 for mids and other for subs. It seems every time i run over a rough surface or something, i get a pop from my speakers, or the music will turn on, and then it might turn off on another bump. I dont know what the hell is going on, and I know its not the cd player, I think it might be a ground somewhere, maybe the main ground, which is grounded from my motor to part of the suspension. I think maybe the ground ripped away from the motor and is dangling and messing with things. Also my motor will sometimes feel like it wants to just shut off, almost like it has no gas, but it has gas, I think the problems could both be linked. any help advice, etc greatly apreciated. Btw, its a 2000 ford mustang gt and I have checked the power and grounds to both amps, they are both intact and well connected.
