I've developed a nasty buzz/rattle from the cover for the JL Audio Stealthbox. Don't know if it's because of parts contracting due to the recent cold weather here in the Arctic zone or what. If I put gentle pressure on the cover, the buzz/rattle disappears. Any ideas on how to get rid of the buzzing permanently?

 

Lock someone in your trunk, make them hold it down while you drive

 

I tried that, but it threw off my 50/50 weight ratio.

 

put some dynamat on the underside of the board and anywhere it might touch the car.

 

Thanks.
