I am pretty sure that my friend is now on a whole new level of installation. We just spent 3.5 hrs installing a headunit. Why 3.5 hrs... because i drive a 96 ford explorer eddie bauer w/factory amplified jbl system, which has a dead unit and we basically had to take that complex system and turn it back in to a normal set up just so i could install my head unit. i will be puttin my subs and amp in tonight. Also has anyone ever tried to tackle that jbl system, just curious.
