Hey, here's a dumb a$$ question. I got a BOSE subwolfer with wiring for my 1993 Camaro. (the car didn't have a sub OR wiring for it) The wiring was cut on the head unit side when I got it. I need to know which wire goes to what!! There are 5 wires all together (orange, black, blue, brown or purple, and I can't remember the other one) I think it must be orange is power, black is ground, blue and brown are rear speaker +, and the other is a rear speaker ground, but I am not sure. Any help please, I want to get this wired up and back together. THANKS!!
