Chrysler didn't wire the back speakers separate they combined the front and back. I will meter the pre amp output to make sure of the voltage. See my logic is not bad but my writing took a big hit- not to say it was any good to start but the stroke sure gave me a great excuse for what is now the worst expressive writing.
Off the top of you head, do you know where the ACC line 'in" from the car comes from? My fuses are all good, so i probably burn the line "in"
Still trying to trace sons problem with the sensor, his car restart after awhile then when you restart run to normal run temperature it shuts down and the cooling fans go into overdrive (really crank up to MAX)
