ok heres a tricky one. i got a 91 econoline van in the shop today for a new headunit. well after i wired it all up, i got no output from speakers. so i start testing pairs of speaker wires for ohm loads and i got weird numbers like 55 and 67 ohms. so i looked behind the ford harness(factory side). this harness has 8 wires, two for each speaker, but on the factory side it only had five. four for the positive wires and ground so i realize the speakers are common ground. so i grounded all 4 negative speaker wires and still got nothing! i looked around and found what im pretty sure is a factory amp way back in the dash to the right. im wondering if there is a way to bypass that amp or if I have no choice but to run new speaker wires to each speaker. i set her up an appiontment for sunday. i couldnt do it today bc i had other appointments waiting for me. what was supposed to be a 20 min headunit install is now possibly an hour of running speaker wires. if anyone knows a way to bypass that amp please let me know! thanks

did you check for a factory mute? should be a blue wire that needs 12 vdc. i had the same trouble from a 92 explorer.
