I've never tried polyfill, and never seen a reason to. I've heard subs back to back with and without it and can't notice a difference in outside noise. It IS however, supposed to give smoother/sharper hits on the 40-120Hz range.

Another thing you can use to deaden sound is roofing tar strips. It's the same thing as Dynomat but without the shiny aluminum on one side. I've got it in my trunk and it does the trick. Cheap too.
