I'm replacing the subwoofer and amp, but I want to retain the stock console subwoofer enclosure. Those of you that have done this, what have you done with the factory amp/wiring? I'd like to remove the amp and wiring, but there would obviously be a huge hole in the enclosure if I did that. Does anyone make a block-off plate? Or do others just cut the wires to the amp and leave it in there?
