Speakers not working??

[a_high@comcast.net]

Alright so after two years of being in the shop my cabriolet (1993 collector's edition) is finally out of the shop, unfortunately only one of the speakers is working (the right door panel speaker). I tried replacing the left door's speaker, HOWEVER the replacement didnt work either. I assume the wiring is faulty. I checked the back 4x6 speakers and they both looked like they were in good shape, yet neither of them are functioning? Is it possible that this is all being caused by a bad fuse?

The wires usually brake in the rubber grommet going from the door to the body of the car.

awesome thanks I'll check it out!

I had the same issue when i got my 95, problem was actually a short inside the radio. If you have another to test with might not be a bad idea to try. It took me a ridiculous amount of time to discover this through process of elimination.

What radio? Are the front lower speakers aktiv (amplified) or not?
On non-aktiv head units, speaker output can be tested at the speaker wire connections on the back of the head unit with a DVOM set to a low AC voltage range. If you've got speaker output on the HU, test again for AC voltage at the speaker connections. If there's no HU output, get another one.

I had this problem in my 1992 cabriolet, and it was the broken amplifier that caused the speaker not to work.
I just had the entire thing rewired, solved all my issues

yeah i ended up taking off the door panel and discovering the wires were broken, i replaced them and the front speakers are now operational. Thank You!

Thank you for responding that the problem was solved. Glad to be of help.

So as I said I got the front speakers working. One was broken just because it was rusted. So I replaced both front speakers. The rear 4x6's still aren't working at all. I took off the side panels, thinking they would be rusted too, but they looked fine and they were connected properly. My question is, could this be a problem with the head unit, (which is rated to power 4 speakers and I already checked to make sure the fader wasn't in the front). And if not I'm thinking the wires could be shorted somewhere.

If the rears aren't working, then as Ron said is it an active system.

You can take the head unit out, then using a 9vDC battery and a couple of jumpers, power the rear speaker circuits with the battery, you should hear a click pop or scratchy sound.... if not, then Remove the speaker on one side or the other remove the speaker, and with the battery attached to the speaker wires at the head unit, measure the wires for voltage, 0V and you have a break in the wire or ground....

Use the Speaker ground to measure the voltage first as you are on a continuous circuit. Speakers when rated for 4ohms or 8, is a Impedance value and not the actual physical measurement of them.

Chances are that the head unit is ok, and the speakers are shot.... but you never know until you eliminate the different possibilities for the answer.
