What is the reason for no sound from the two rear door speakers?
2 Answers
This is because the vehicle's sound field adjustment is set to only play sound from the front. Car audio maintenance: 1. Head unit maintenance: Most vehicles today are equipped with CD players. High temperatures and humidity can directly damage the lifespan of the laser head, so during intense sunlight, it's best to use a sunshade to block direct exposure. 2. Speaker maintenance: Dust damage is unavoidable, but its impact can be minimized. Ensure good door sealing, and when driving on dusty roads, keep the windows closed as much as possible. If there is dust on the head unit, wipe it with a damp, wrung-out towel. After cleaning the interior, it's advisable to leave the windows open for a while to let most of the moisture evaporate before closing them.
I still remember last time when the rear door speakers of my car weren't working. After checking for a long time, I found out the balance setting in the audio system was misadjusted, focusing only on the front door sound. If the settings are correct, it might be due to loose or aged wiring. I always enjoy listening to music to relax while driving, but the silent rear seats made my family complain constantly. I removed the door panel to inspect the connectors and found oxidized plugs. A light sanding with fine sandpaper restored them. If the speaker is broken, just buy a new one for a few dozen bucks and replace it. Be cautious with electrical issues to avoid short circuits and fires. Regular audio system checks can help identify problems early, preventing minor issues from turning into major repairs. It's advisable to start troubleshooting with the simplest solutions first.
