[A4] ratling speaker

[Jonathan]

Hi,

I have a 96 A4. The front speakers used not to work until the volume was 
really turned up loud, which caused a really bad rattling sound. Taking it 
all appart, got the drivers side speaker to work, but rattle like there is no 
tommorrow. Took the whole speaker out of the door, and it still rattles. 
Ergo, the speaker is rattling with the bass, not the door. Any ideas how to 
fix the speaker?

thanks

Jon
