I've got a Sony Xplod amp and a single Kenwood 12" sub that worked just fine for quite a while, then all of a sudden my amp's overcurrent light came on and the sub is quiet as a mouse. I read in the manual that the problem is the L and R speaker wires are somehow touching somewhere between the amp and speaker box. But, when I checked the wires, they wire into the amp on opposite ends so there is no way thats where they are touching and obviously its not @ the box terminals. What am I missing here, fellas??
