take the lights off. put deadener or foam between the lights and the metal, then put the lights back on.

Foam? What kind of foam?

Because my trunk rattles a-lot too, and I used sound deadener but I still get it pretty bad.

3/8" thick open cell weatherstripping-worked pretty good for me, the taillights stopped rattling against the bare metal

If with the driver door open the rattling goes away it seems to me that the door needs to be deadened. That doesn' t make any sense.

^x2... Im not sure what you meant by that. When you open the door all of a sudden ur system sounds perfect? Have you tried listening to your music with the windows rolled all the way down? With the trunk popped open? I gess peel and seal works ok but I think that stuff is pretty thin. What I would suggest is to try and find the rattles while the music is playing. Then where u feel or hear rattles add deadening till it stops. Try using something thicker like eDead or dynamat.

if you can..... and want to fix this problem. THis sound deadening method should work with good results. I tried this with a VW jetta, and worked out well.......

First remove your trunk. remove the lights, pull the wires out as much as you can, and secure them down with tape. now mix some of this.....


and fill all of your gaps and voids... Once it has set strong, you can grind and sand it down to shape. YOu can either leave it unfinished, or you can carpet it as well. However I went further and fiberglassed over to make a shell and put the JL logo that was cut out of 1/4" plywood in there, and covered it with carpet to match. The logo stuck out and it looked SHARP! It also cure all of the rattles in the trunk. I also use weather strip behind the license plate. Dyna mat sells a license plate kit but is bogus as to compared to the weather strip. Weather strip has many uses for sound dampening and making seals. try that... YOu can also use this for many fabricating purposes depending on your creativity.

ooo that should work nicely. I hate that stuff tho. Dont let it touch anything else. X2 on the dynamat liscense plate. Its a waste.
