Bass speaker making loud intermittent noises consistently

[Mozzie]

Hi,

 

I hope you can help me with an unusual problem.

 

The bass speakers in the doors are making loud noises of their own accord. As soon as you unlock the car the speakers make a deep, intermittent noise. This is not related to the radio (turn the radio down or off but the noise continues). Also if you get out the car and lock it, the noise continues and stops by itself. It is not consistent. There seems to be nothing you can do to affect it. It is rather loud - at the edge of the speaker's ability).

 

I have a link to a short video on the problem (sound quality on the camera is not good): 

 

Any ideas on the possible cause are greatly appreciated. 

 

Merci,

Marcel

If it has come by itself, generally, a faulty amplifier is the cause. Check this out properly.

It might help to know what year and entertainment system your car has. Try pulling the fuses, D8&9? to Reset the system.
