Alright so I have a 95 mustang gt, just got new 10" subs cuz none of my 12s would fit in the trunk. Yesterday my dad and I decided to finally wire the car so we did the head unit first... well it turns out we bought the wrong wiring harness... My mustang is fully loaded and has some mach 460 stereo system in it so to hook up my head unit i need to find a different wiring harness that will power all of the speakers. also there is two amps in the trunk that are stock for the speakers.... best buy doesnt know what we are talking about.. and we look around at other places and couldnt find one.. anyone know where to find the wiring harness for the 6 speaker system?
