OK, I just put my system in (kicker solobaric l7) and it sounds AWESOME inside the car.. from the outside, there were 2 big rattles. One was where the M A X I M A letters were on the trunk, and one was the LED's in the spoiler brake light. The MAXIMA rattle was fixed by my handy dandy screw that I put from the inside of the trunk, forcing the trunk lid out, so it couldn't vibrate. Sounds perfect. Now I have 1 rattle left -

The spoiler LED rattle - what in the world do I do??? I have no clue, maybe take it apart and put like cotton ball pieces in there, I mean what the heck..... any help? What have you other sub'd boys do?

You're not alone. I'm sure most of the Max owners out there have the same problem with that led rattling. It's a pain.

I had a local stereo shop pull off the led and put sound deadener on it, cost me like $5 or something like that. . . It was this stuff that is black and sticky that comes in lines. . .they stuck it on top of the LED bar, and it did the trick for me. I forget what they called it, but it worked. You could also stick Dynamat under the LED bar. . . That might help, although it looks funny. I know that even though the LED doesn't rattle anymore, the spoiler does. . . Also, what size screw did you use for the Maxima letter rattle?

size of screw...
 

I don't know, here is what I did.

I found a screw in our box of random screws in the basement, got a matching wingnut, and took a glove and cut two of the fingers off.

I put the screw through one of the "already there" holes in the trunk lid under the liner (had to pull all of those little clips off) screwed on the wingnut on the inside of the trunk lid, and put the gloves over the end of it as to not scratch the trunk lid/eventually pierce it. I then screwed down the wingnut real tight to hold it in place and to pressure the MAXIMA emblems out.

I have promised someone else pictures, I just have to remember to bring the digital camera home from work one of these days... doesn't look too pretty, but there is NO trunk lid rattle anymore :) and thats exactly what I wanted.
