When I listen to something with a wee bit of bass on my Monsooon system in my '02 GTI the passenger door will occasionaly buzz. It's not the speaker (because it doesn't happen on the driver's side) and if I lean over and grab the door handle and pull it towards me it goes away. So obviously my door is buzzing. Should I take this in to the dealer or do you think they'll just tell me to turn down the bass? Anyone else experienced this?
