I had an issue a while back with the tweeter in the front passenger door crackling. Sometimes it would crackle on a bumpy road. Sometimes it would crackle when the door was opened and closed (all systems off).

It took the dealer a painfully long time to find the problem, which was relatively simple in the end. The at least one of the connections on the back of the tweeter was actually in contact with the door frame. After so many miles, it wore through the paint and started to contact metal. The solution was to insulate with tape. I suspect it is possible to wear through the tape after many many miles, so maybe it will return someday. I also suspect that many of you will incur this problem, eventually.

 

Thanks for the heads up. I wonder if the connector could be bent or moved just a bit to prevent a reoccurrence in the future.

 

I questioned that myself. But the technician said he didn't want to bend a soldered connection. I respect that.

 

I hear something from the front driver too. But it's when I go over a bump. Sounds almost like a loose speaker?
My question is what sound system do you have the factory or b&w?

 

Factory. Grab the plastic housing around the tweeter (the highest speaker on the door, in the window corner) and squeeze it. You might be able to excite it this way, if it is indeed the problem.
