Instructables

My speakers only work on one side. Both speakers are good but the right side doesnt seem to work. any suggestions?

I have a mazda protege and was changing the speakers when i noticed that the right side speaker doesnt work. I tried both speakers on the left and it wasnt the speaker that was the problem. I figure it is the wiring, but i am not sure how to fix this. any help would be greatly appreciated.

Tap on the balance and volume controls just for giggles and see if you hear the speaker try to come on. Another method of detecting a faulty switch ( volume and balance) is by listening for a scratchy sound when rotating them. If the radio is defective there is no use trying to repair it unless you are very experienced with diagnosis and audio circuit repair. You can check the wiring with a continuity checker once you've establish the correct wires for that speaker at the main plug in the rear of the radio and easily eliminate it as the culprit. Check the door jam ( in the hinge area) on the side with the defective speaker too and look for broken or mangled rubber harness cover. Wiring may be broken or shorted. A wiring diagram would be handy too. Google for it, good luck.

It could be the wiring, but having one channel fail on an amp is not uncommon - need new stereo perhaps? L

It's doubtfull that the wirring is at fault, as sound 91 mentions take the radio out of the dash, if it has a multi plug type connector which can be removed from the rear of the audio you may find a connection diagram label on theradio chassis. Identify the + & - right side speaker plug connections and connect a small penlight battery_ you should hear a distinctive plop from the speaker if it's ok. Otherwise your audio is at fault. Hope this helps

I would definitely take your radio out first, so then you can do other tests on the wiring, the radio, and the speakers without too much hassle.

Well I don't know ho to describe how to replace the Wires in your car, but maybe it aren't the wires. You have to check the car radio, too. Maybe you can pull the whole thing out and check how the Speakers are wired to directly connect your speaker there to the right channel. Or yet easier: Maybe you have another radio to check the speakers with this one.
