I used the pre-amp control from my new receiver to power the Xfire AMP and the speakers worked (good news). Chrysler however didn't provided separate front and back wiring, just right and left...
The other Ops, I shorted the ACC on the Xfire side, replaced the fuse but still can't get key-on ACC power from the the car ACC. Have to trace that out; a work around - I put the ACC of the radio to Car Battery + for now and that works. Not the best way but it will help me setup the other fuctions till I fix or re-run a new ACC line for the new radio from the car.
