Finnicky Speaker!

Hey guys, there is a speaker in my car that only works sometimes.

I have a 2011 328i with the Harman Kardon system, and its the ~3in diameter speaker in the front left door (right above the window controls) that doesnt work sometimes.

I've only caught it not working 3 or 4 times now and one of the times I was able to rap on the speaker itself with my knuckles and the sound flickered in and out.

Because of that I feel like this is either a speaker issue or something to do with the wiring connection to the speaker itself.

I haven't investigated further yet but I wanted to see if anyone had any recommendations or if anyone knew if this was a common problem with an easy fix?

My plan of attack is to take off the door panel and inspect the wiring and speaker, if nothing seems wrong there I will probably try to find a used speaker on ebay or something to put in there.

Any advice? Thanks!!


Speaker shown here right above the window controls.

Your path for repair is correct.
Not common for the speaker to go bad

Thanks for the links. I too thought it was odd for the speaker to fail so I'm really hoping its just a loose connection behind the door panel or something.

I will update this thread once I dig into it.
