Buzzing Noise from Car Speakers Not Running Transmission
If you’re hearing a buzzing noise from your car speakers when the transmission is not running, it’s likely due to one of the following issues:
Ground Loop
A ground loop is a loop in the electrical system that allows AC current to flow through the ground wire. This can cause a buzzing noise in the speakers, especially when the engine is running. To fix a ground loop, you need to find the source of the loop and break it. This can be done by disconnecting and reconnecting wires, or by adding a ground loop isolator.
Alternator Noise
The alternator is responsible for charging the battery and providing power to the electrical system. If the alternator is not working properly, it can cause a buzzing noise in the speakers. To fix alternator noise, you need to replace the alternator or have it repaired.
Faulty Speaker Wires
Faulty speaker wires can also cause a buzzing noise. To fix this, you need to inspect the speaker wires for any damage and replace any damaged wires.
Loose Speaker Connections
Loose speaker connections can also cause a buzzing noise. To fix this, you need to tighten the speaker connections.
Faulty Head Unit
The head unit is the control center for the car stereo system. If the head unit is faulty, it can cause a buzzing noise in the speakers. To fix this, you need to replace the head unit.

In some cases, a buzzing noise from the car speakers can be caused by other factors, such as a faulty amplifier or a loose ground connection. If you’re unable to find the source of the buzzing noise yourself, you should take your car to a mechanic for diagnosis and repair.
