deadening

    What all does dynomat sound deadening do?

    My car has a bad trunk rattle when the subs hit. I was told that dynomat would help fix it, but I was wondering how much less bass would be heard outside the car after dynomat is installed. (Only in the trunk)

    Is this stuff as good as Dynamat for sound deadening in my car?

    What would be good sound deadening material to use in my truck?

    Its a truck, so it has to be cheap but effective. Any suggestions?
