stopping my trunk from shaking
 

is there anything else i could do other than getting dynamat? cause the one for the trunk is expensive.

The trunk kit just costs more because it is precut. Just get the regular stuff, but your going to need it. Only way to get the trunk to stop resonating is to bring the resonance down, only way to do that is to add mass. You don't have to use dynamat brand, there are others that work as well, just google for what people recomend. I used dynamat and happy with it. Only real problem with the cheap stuff is it can come unglued, or may not be as dense.

alright, thanks
