Thanks for the info. Any pictures of this project? Or any other projects?
I would have like to added "Mass Load Vinyl" to my Axis. But I have already added 2 to 3 (Even 4 in spots) layers of Dynamat / Fat Mat to bottom of the dash and Fire wall (from under my hood),and inside / under dog house.
If I had to do it again I would start with Mass Load then two layers of the other stuff. They say ML is the most effective barrier for sound.
But im very satisfied with my results. 10 x better than OEM.
