Does anyone have experience with sound deadening?

Dynomat thin stuff 100% of the trunk pan anywhere you can, dynomat thick mat in spare tire well and top layer of trunk, put trunk carpet and spare cover back in, then TKO trunk mat over it all. My car is quite loud, and can barely hear it inside the car. I also have resonators, and j-bends killing the drone too.

use some dynamat under the trunk carpet and rear seats then add this to your trunk. won't solve it but will help a bunch

I have one and not impressed. It may work better on a coupe, but not enough of a difference in a vert.
