The deck is a normal 50 x 4. The factory speakers in the front are shit, and i think they blew out. Either way, i consulted a mobile audio technician at futureshop, and he said chances are that one of the wires is grounding. The deck isn't that powerful, just an ordinary pioneer deck. I was going to get futureshop to install it, but i thought i would go the hard way and learn how to install myself and save 50 bucks Better to learn and screw up than to never learn at all.
