Let's start with some info on my car:
1986 Grand Marquis Station Wagon with Digital Factory Radio, 'Premium Sound', and other exciting/mystifying options.
Ordered the head unit from crutchfield (http://www.crutchfield.com/p_020CZ10...9.html?tp=5684), along with the wiring harness, mounting kit, and this thing. Crimped everything together, bypassing the PAC for the left and right rear negs and pos's. Put front speaker lines thru the adapter, yata yata yata. Put the front speaker positives to their appropriate wires, and put the front negatives, along with the ground to the 'common ground' wire on the harness (Used the multimeter for this to make sure i wouldn't be messing things up). Amp turnon, etc. Plug the radio in, no flames: yes!. Turn it on, sounds promising. Music. Back speakers only. What gives?
I've attempted looking through the forums for people using crutchfield or this strange adapter, but almost all i've read of is people rewiring to the front speakers. Is there any easy way to get the factory amp working so that there's no rewiring? Or should I settle in for rewiring the front speakers?
