I upgraded my headunit to an Alpine CDA-9855, and now when the bass is turned up the window switches rattle like mad. Anyone find a fix for this?

 

Have you tried installing dynamat (or simirar) into the door itself?

 

No.. It's the switches that rattle. Touching your fingers to the switches stops the rattles.

 

Same problem here although I noticed it a lot more when DJ's were talking but also got it with a lot of bass and just certain frequencies.

Dealer fixed it under warranty even with an aftermarket stereo in place. Here is what they did:

"LOOSE R&I BOTH DOOR WINDOW SWITCHES, ADDED ANTI RATTLE TAPE AND SECURED MT"

So far so good..
