Sound Proofing and deadening
 
Got a new carpet and sill plates from BJs and am very excited to install them! I would also like to quiet down the cabin. I have recently added the hood insulator (mine was gone) and have been looking at some stuff from soundproofcow. Some interesting products and info. As a general strategy, I want to address the cargo area first, the cabin second, and then the doors. I might take down the headliner and do something there. I also have noisy tires so that's probably making things much worse than they need to be. Any tips or suggestions?

I used 2 layers of Fatmat in my cabin floor and firewall, I also cut a thick sheet of rubber to use as a cargo liner in the rear ( actually stall matting) thick and it looks great and made a huge difference

Check out Sound Deadener Showdown if it's still around. His theory, supported by testing, is you only need a small percentage of the stick on butyl to take the bong out of the sheet metal. Then a layer of isolating foam, then a layer of rubber.

Must be something to it since the manufacturers like Dynomat are selling the other materials.

Thanks for the tips on the sound deadener website. Lots of good info. I remember reading something like that too about the butyl.

The website is down but available through thewaybackmachine, in case anyone is interested.
