So the previous owner hacked the wiring installing a Sony cd player. I am in the process of replacing it with a Pioneer 4 channel but I have 2 speakers in each door plus the two in the rear. I know enough about car stereo that you shouldn't wire speakers in parallel or series or it changes the ohm load or reduces the power to the speakers...How were these wired? Was the amp in the factory radio or separate? I can not find a diagram anywhere and I hate to rip everything out and start over but I will if I have to. Have Rockford Fosgate punch 6.5"components on the way figure I can fit the tweeter on or in the mirror back or top of door and 4" in the doors upper spot and rear then use an amp and 10" fit into the rear side to fill it out but I may have to run another amp to run the other 6 speakers if I can't figure this stock set up out. Deck is 50/22 x 4 so enough to run the 60/30 speakers fine if just 4... I may have to just not connect the 4" in the doors as the 6.5 components might be good enough by thethemselves....anyone?
