Rattle Locations in Buick

[orion]

Im installing subwoofers in the trunk of my 87 GN. Im thinking of a small setup by todays standards 2 10'' alpines most likely, 300w continuous each. I was where the trouble spots for rattleing were located in the car so i could deaden them ahead of time.

Ones I have found...

-taillights to body.. make sure is something in between
-license plate holder... this one drives me nuts. still havent fixed that one yet
-3rd brake light..see that the rubber seal on the back isnt against the rear window or you'll hear it. you may have to adjust it forward.
-trunk latch... just adjust the rubber stops to get a good tight seal so there isnt up and down movement of the trunklid
-dome light lens.. make sure that is in tight
-on vinyl top cars, the trim around the top is a pita to stop
-rear molding above window (inside car) ...stuff with foam
-thin metal piece at outside base of rear window..I used spray foam for that piece
-if using the "package tray shelf" to put the box on, I would suggest some material on that underneath the box.

those are the major ones I can think of off hand when I did mine. you might also get the rear qtrs vibrating a little, so youll want to put some damping material on those as well.

if there are others... believe me, youll find em soon enough

To fix the liscense plate rattle, put some thin foam or dampening mat (non-foil backed mat) between the plate and the holder.
