Stop Sub Rattles on Raptor 300mp

I have a 2012 Raptor 300mp with the factory sub installed. It makes the stereo sound much fuller, but it drives me insane. When it's on even at low volumes it vibrates the fuse box cover next to the sub. Makes it sound like a blown speaker. I can't leave the door open on the fuse box (helps alot) but would like to get better sound.

Has anyone messed with this, or found a neat way around it. I have thought about a different sub box put into where they have it located, but don't know how much air space is back there for a box. Dynamat maybe? Love to hear any suggestions.

Mine does the same thing! Ive found that opening the cabinet door works, have not had to mess with the fuse box cover. It does really suck to have a pretty good system and the sub sounds like junk.

Have you tried to use some type of tape, foam or some other method to prevent the fuse box cover from vibrating? Maybe double sided tape with one side left unpeeled applied in the proper place would remove the rattle of the cover but still allow you to keep it closed. Might take a few tries but I think it would work. If tape isn't think enough, might try the little round adhensive pads that you put on the bottom of chairs to prevent scratchign wood floors. I've used those with success to prevent cabinets from banging into wood in the camper when opened.
