Rattling Rear Deck - Plastic Part

[Jmoney2544]

Hey, i've got a 2002 Buick regal and I have around 75 square feet of Fatmat all throughout my trunk and rear deck. I rarely hear rattles but on some notes i can hear high pitched rattling when high notes are played. I know its the the metal thats rattling it the plastic/felt cover that goes over my rear deck above the metal. There's like an air pocket on the rear deck from the metal to the plastic/felt that the 6x9's are in. The metal part is already all covered with Fatmat. What's the best way to keep that plastic part from rattling? should i fill it in with some foam or what?

I use great stuff on deck lids, works like a charm

Great stuff is Great stuff.

have any old comforters lying around? or willing to buy some polyfill?

pack that area with polyfill and it will stop it, no chances of squeaking either

Personally, I prefer a closed cell foam (can be bought at all sorts of craft places) because it won't trap or retain any moisture. Just shove it between the sheet metal and the plastic bits and you're good to go.

Way back when I first sound proofing cars, I used the blue or white swimming pool liner foam stuff, worked really well and dirt ass cheap for a 500 sq. ft. roll of the stuff.

Well said, but I suggest.
