Hi Joe
You might want to overlay the Dynamat with some Dynaliner under the carpet- the black HD foam with the adhesive backing. They offer a 3mm and 6mm thickness. The 3mm moulds easily to the floor shape. Provides a bit of underlay springiness to the carpet and stops some of the transmission from the Panteras patented Seating Heat Integration Tunnel ( you can do the initials )
Just a thought.
