Thinking of running all new wires to the front door speakers but I have not been able to locate a good write up on taking out the head unit and where to run them through on the dash.

Look at your schematic and find the wires that go to one of your front door speakers.

Take your multimeter and attach one lead to the wire at the speaker and touch the other lead to the corresponding pin on the wiring harness.

You should hear an audible tone. If you don't hear a tone you have a break in the wire.


But you could skip all of that by running a new speaker wire from one set of pins on your wiring harness to a single speaker... pick any one, but I'd go with a front door one because it's a short run. When I say pins, I mean the wire coming off the harness... not the actual pins.

Don't bother making it look pretty, just wire it direct and see if you get sound.

It's very possible you have broken wires and just need to run new speaker wire out.


If you have a spare, junk speaker lying around try and hook it up direct to see if sound comes out. That way you don't have to uninstall the speaks you already have in place.

What we're trying to determine is if sound is leaving the head and getting disrupted before it hits the speaks.

If you hook up a speak with new wire and sound comes out, then I'd do all four.

If it is still silent... with no hum or vibration, then move on to plan B.

So I take the radio out and thought there was a short so I bought a brand new radio. Doesn't fix it. Take all my speakers out and they were junk. I replace them and still nothing. I get my test light out and check the speakers wire from the adapter to plug into the radio and there's nothing. I have no power to any of my speaker wires. Someone please give me something to work with!!
