Sound deadening...

So just thickness then? Cool, maybe the 80 or 150 mil they have for more density...

Specs show 50mil vs 60.

My current car has been done with brown bread mat. Previously I've used dynamat and another high end stereo deadening mats on other builds. IMHO brown bread works 90-95% as good as dynamat with much less cost (at least when I bought it a few years ago) The only difference I found is dynamat cut a bit easier and didnt have as much edge bleed. It made a large difference in road noise, drone and cabin heat in my car.

I've used fatmat in 3 of my cars works good only 50 mil I believe. Ive done all the doors of my fox and the floors maybe 60%.
