Posted January 20, 200916 yr Not sure if this is the correct place to post...if not, mods, feel free to move!I recently installed a HU for a friend. She has a 1989 Ford Taurus. When she bought the car, the front speakers didn't work. I replaced the speakers last spring, and that did not fix the problem. This past weekend, I installed a Pioneer HU, hoping that would correct the issue. But, no, it did not. So I am wondering...could I just splice new speaker wire into the Pioneer side of the harness, and basically run new wires to the speakers? In doing this, I would bypass the factory wiring, hopefully solving the problem. But, if I bypass the factory wiring, won't I also bypass factory ground? Or does the HU provide a sufficient ground for the speakers? I figure if necessary I could just ground the speakers somewhere in the door, and just run new power wires from the harness.Sorry for the long-winded explanation, but I wanted to be as clear as I could be. I am going to try to fix this issue this coming weekend. I have asked this question on another forum, with no real results. Hoping you guys can help me out!Thanks!geo
January 20, 200916 yr no no whoa.. just run new wires from the door speakers to the head unit... no need for a new ground but it never hurts either... dont ground the speakers to the doors.... a speaker works off AC power not DC. but you may have another issue does the car have a ford premium sound system in it? if so your problem may be that you need a factory amp by pass.
January 20, 200916 yr Author No, the car does not have a premium sound system. Just basic factory HU and speakers. Also, when I installed the HU, the rear speakers still work fine. Just the fronts do not work at all. Thus my diagnosis of a wiring issue somewhere. I was under the assumption that the speakers pick up ground via the factory harness, which is in turn grounded to the frame/uni-body...etc. So I don't have to worry about making new grounds? Just pull a new set of wires, and I should be good to go?Thanks again!geo Edited January 20, 200916 yr by geowick07
January 20, 200916 yr sounds like you may be talking about an old common ground radio.... no just a new + and - for each front speakers.... run them in to what should be the grey and white wires on the head unit.
