I helped a buddy remount his amp about 2 years ago. We were trying to be fast about it and I think we forgot to disconnect the negative battery terminal during the removal/reinstall. Turns out somewhere along the way we blew one of the amps fuses. I dunno if this could have happened to you but it's all I've got. Good luck.
