on ebay they have a dynamat license plate kit.. if you already got that, my friend has 2 - 15's that run about a 1000 watts, way too much bass for me, but he had horrible license plate rattle, we dynamatted his entire trunk and it moved alot of rattle into the license plate..
we figured out it was vibrating in a lot of places on the license plate.. we used that sticky stuff called tack or whatever, the stuff you can use on walls and whatnot and stuck some in between the plates, i wouldnt put it on your paint though.. it worked really really well, so pin point were the vibration is first.
but anything sticky and thick you can jam in there will work.. (suggest the dynamat license plate kit though)
