Worst I've seen, Power and ground wires running through the fenders to the HEAD UNIT, ALL speaker wires running on top of the center console to some 6.5", in a box from Wal-Mart. The amp was sitting in the passenger seat with the worst wiring ever (splits almost grounding out the entire car.) Power and ground ran through the other fender (no inline fuses.) Speaker wires ran through the top of the rear seats to some Technic HT subs. The only good parts about it was the wiring (brand only), and the head unit. He did choose a nice head unit and wires for it. It was in an 89 Tempo or something like that. I've only seen it once, and then it broke down.
