Hello, first off IM NEW HERE.
i just got my avic-z1 about a month ago, i installed it fine with the bypassed wires and everything was fine. but i then i was testing out something in my brothers car when all the sudden the 12v constant wire touched the ground wire, and the cars FUSE burned after we replaced it, it seems that the subwoofer OUTPUTS dont work anymore. all i hear is MONOTONE bass that doesnt bump or do anything. i got the unit off ebay as factory refurbished so i called pioneer customer support and they couldnt do anything because EBAY isnt a authorized pioneer dealer.
PLEASE
