Why isn't my door speakers working?

There could be several reasons why your door speakers aren't working. Check the speaker wiring for any loose connections or damage, as this can prevent sound from reaching the speakers. Additionally, ensure that the audio source is functioning properly and that the balance settings on your stereo aren't skewed away from the door speakers. If everything seems fine, it might be a problem with the speakers themselves or the car's audio system that may require professional diagnosis.
