Well he was trying to push in his hu after taking it out and all of a sudden it just turned off...he looked and seen a wire came untaped RIGHT by the back of the HU... do you think his subs or amp will be damaged if the HU shorted?
well that, or it was the power/ground that was disconnected. Also, are the wires only taped? If so, give your head a shake and at least use crimp connectors.
