remember, all these are meant to dampen vibration in metal panels. drumming is common in metal, a bunch different in glass. a 76 and up metal floor will have an effect, earlier, the foil side will reflect heat but drumming i don't think is an issue. use foil to reflect heat back down through the floor. bout as good as you can do.

There's sound deadening material, and reflective/insulative material. Attenuating sound requires adding mass, and changing the harmonics of the substrate. I believe the Grace ice and water shield I have left over from a recent roofing repair will do the trick there. I added a layer of Reflectix; a reflective/insulating material over the Grace product. Both of the layers together are only approximately 1/4 inch thick and don't seem to interfere with carpet installation, although I ran out of Reflectix before I finished the front floorboards. Rear carpets and storage box assembly went in perfect though. I expect the result will rival if not surpass the vastly more expensive "commercial" products.

i used relectix exclusively on the re-build of my 78 and it has been of tremendous help in reducing cabin heat levels. i would also suggest if possible that you do the best you can to use it to line the doors also as a great amount of heat has always "rolled" up the body sides on corvettes of almost every generation.

Only needed if you like to BASS a certain type of music on your highly amped and sub woofered stereo. Not needed on my car with '70's and '80's rock. Modern music of a type I do not understand has a VERY hard bass line that is designed to rattle the windows of the car three lanes over. These products keep your car from vibrating itself into little pieces. mike...
