Dynomat. Happens on every car. Depending on how silent you want the car to be you'll have to dynomat the trunk and anywhere else you hear rattling. Tip: Remove your license plate and place dynomat under it, then mount it on top. If you have a hair dryer you can do it yourself or go to your local car audio store and they can professionally install it, but it will run some loot.
