Speaker buzz, new symptoms

[sunstealth]

the fix is really simple, i too had it !

the silver trim pieces on the door pull, remove them then test out for the noise
i can almost garantee it's your buzzing source .

in mine what fixed the issue was removing those trim pieces, tightening the screws under that trim piece 1/4 turn, and lining the back of that said part with moleskin, never buzzed again

I had something like this I brought it to a dealer and they said it was a bad connection at the speaker.

just read one of the later posts and it seems you got it fixed already.
