Last nite when I was hooking up the remote and speaker wires to my tweeter amp, two of them made contact and suddenly all of my amps turned off. The head unit continued playing the cd, but none of the amps are working now. I heard a short sound when the wires touched that sounded like a fuse popping maybe? What should I do? Also, the headunit stays on now even when the car is off! It will drain my battery for sure. Please help!
