the remote wire touched the ground wire and sparked, now the headdeck wont turn on. the fuse at the fuse box was broken so I replaced it. The fuse on the headdeck and amp are fine, but it still wont turn on, do you think the wires are fried? also the fuse box says the fuse should be 7.5 but it had a 20 fuse in it. any help would b great thanks.
