Calling Tampabaylightning
I also have the DX-7's in my L and did not do sound deadening material. I am in the business however and the Dynamat is the industry leader. Weighs alot though - something to consider.

Rob:
Dynamat Premium(Black with gold lettering)is a must.
The reason for the premium is this.... It conforms much better with heat and doesn't tear. I used both because I couldn't find enough Premium.

Good Luck and have fun!
