Ok here's the deal. I wired in the 12v wire and acc wire to my car and had it all hooked up to my deck. Well the last thing i connected was my ground. When I found a good piece of metal I touched the ground to it, it sparked violently and then my head unit started smoking! What the hell did I do? Did I just kill my new deck.!!!!!! Did I just blow a fuse??? What does a blown fuse looki like!
