I have 2 12 JLw3s that hit really hard. My back deck rattles really bad. Ive tried tightening down the griils, wedging carpet between the back window and the deck. Almost everything. It helped some, but anyone have any good ideas on how to stop the rattle?

-Thanxz-

P.S.... anyone have any thoughts on side marker lights???

 

I had the same problem. This may be kinda crude, but it works.

I put dynomat directly on the grills . 5 small separate pieces around the grill edges to be exact.

 

hey.. great idea....

i have only 1 12'' and my deck rattles. i'll have to try that.

 

i crawled in my trunk and put new screws in to the back beck holding it down, also it will rattle less if you have the windows or sunroof cracked or open and the trunk pass thoru open as well
