In my drivers side headrest, only the outer speaker works. In the pass side, both of them work. It may be possible that I have the polarity switched on the front dash speaker so I will check that, but what could cause only one speaker to work in the drivers seat headrest? The wiring to each seat only has two wires correct?
Thanks
I was told that if I disconnect the front speaker and reconnect it , that may make both headrest speakers work in the seat, but I changed my dash speakers (obviously doing that disconnected and reconnected the wires) but it didn't fix the issue of only the outer speaker working. The one that works doesn't seem blown , it sounds fine, but the inner one on that side is silent. I'd really rather not have to take the seat skin off.
Thanks

Each seat should have four wires going to it. Two for each speaker.
Your likely choices are either a cut/broken/disconnected wire, or a blown speaker.
I'm betting on the blown speaker.

But wouldn't a blown speaker make a godawful sound? Not just be silent. I'm hoping its a cut wire somewhere accessible. Are there connectors anywhere that I can look for (other than inside the seat or at the back of the radio) ?
Thanks for your help.

In the 84 and 85, there are 4 wires in each seat harness. Two for each of the speakers. When installing 85GT seats into an 86 or later Fiero, you will have only 2 wires going to each of the B pillar speakers. You must cut and splice and route wires from the passenger side, over to the driver's side in order to power the second seat speaker. Likewise for the passenger side, you must connect wiring from the driver's side speaker to power the second speaker. Just match wiring colors. I've found the task to be much easier by cutting wiring from a junkyard 84 or 85 to allow me to tap into the chassis harness and plug directly to the headrest speaker harness.

I agree with him, sometimes they will make no sound at all, my Burb has rear roof mounted speakers that have a woofer and a tweeter and the woofer was shot but the tweeter still worked so I have seen just one speaker go before, it is not all that unusual. you could also have a bad wire going to the seat or in the seat.

maybe this will be some help.

If u decide u need new speakers, I have a set of Polk replacements i bought but no longer have the headrest speaker seats.

Actually, i have a lot of speakers of you need them, including 4x6 for the rear that i haven't posted yet.

the connector from the seat to the wires is visible if you move the seat all the way forward and come from the outside back and feel for it.(at least on my ragged seats). check the connection and trace back along the ground to the radio. could be a door sill screw cut it or any other possibility. if all wiring is good, then its the speaker.

Man, I sure hope its a wiring issue outside of the seat. I dread the thought of having to replace the headrest speakers. My leather seats are sooooooo nice !

Don't worry too much. If necessary, i bet an upholstery shop could do the job easily and cheaply. Peeling off the seat cover and replacing plug-n-play speakers should b easy for an upholsterer. Maybe you wanna add a seat heater while you're at it

Removing and replacing the seatback covers isn't a big thing. They unzip, peel off by turning them inside out, then reverse and zip up. Kind of like taking off a pair of socks and putting them back on. Just pay attention to how the metal rods inside are installed.

Really? Hmmm then it may be worth changing the speakers out for new anyway, and of course fix any connection issues while I'm in there.
