Hows it going guys, I recently started to hear the rear passenger door behind the driver sometimes throws static or a (kurch) sound during some songs with heavy bass. But when I put my hand on the door it stops. My bass is set on -1, any helpful tips on how to fix this?

 

Do you always listen music loud? With heavy bass? Try hitting it with youre hand when its kurching on plastic where kurch sound comes from.. bolts, screws might get loose from vibration.

 

I get that problem too. I'm considering buying some sound deadening "dynamat" like material to install on the inside of the door panel.
