[QUOTE=TTT]Unless its a two ohm speaker wired to bridge the amp... most amps do not handle a 2 ohm mono load.

Actually, i really cant even think of any Mono amplifier (and being that he is running a 15 i would think he would be running a class D) that cant handle 2 ohms (or at least claim to handle anyway)....

There are a million and one things that it may be. I dont know if i would recommend switching out the amplifier with another being that you are not sure where the problem is. Though if it was a serious problem where there were wires touching (- the remote wire), fuses would have blown or your car would have caught on fire, so an amplifier may not be out of the question
