How To Fix one side of speakers not working in car

An car audio system from the factory will have an midrange driver and tweeter in each door in the front and coaxial system speakers in the rear. In total, the basic factory car audio system has an total of four car speakers in the entire system. Some upgraded factory car audio systems from companies such as Bose may add an additional small compact subwoofer in the boot to give more of an bass sound. If you have noticed that one side of the speaker is not working in your car, either drivers side speaker not working or passenger side speaker not working, we will help you troubleshoot this car audio problem.

The first thing to check is the fader and balance setting on your factory car stereo. You will need to go into the audio settings found within the menu interface of the car stereo. Sometimes what can happen is you can by accident adjust these settings by pressing the wrong button on the car stereo quickly. The balance should be set to the middle and the same should apply to the fader. This will ensure the audio amplifier chip found within the headunit provides an equal rms power output to each individual speaker. If you still are not getting the full sound from your car audio system, there is an possibility the speaker wire for the not working speaker is degraded overtime. Over the years, opening and closing the door daily can cause either an weak or broken car speaker connection causing no sound. The best way is to remove the door boot push it back if possible and inspect the speaker wires for any damage.

If the car speaker wires look ok physically from the outside, then the wiring is fine. The issue will most likely be an faulty or worn out car speaker that is not working. Factory car speakers don't tend to last as long as aftermarket car speakers due to the cheap material they are constructed from. To replace the car speaker you will need to remove the door card.  To help you, you should be able to find an video tutorial on Youtube by doing an quick search. There will be hidden screws behind plastic pop off handles and covers. Then you will need to use an pry tool to remove the clips around the door, sometimes these can break and can fall off. Next remove any electrical connector for any window switches and also remove the handle release cable on the door. Now, you will have full access to the blown car speaker. Usually it is either an Philips or torx screws that you need to remove to pop the blown speaker off. Sometimes, there will be metal rivets from the factory that you need to drill out and apply fresh screw in. Once you have removed the blown car speaker, attach the speaker terminal onto the new speaker and screw it in place.
