Has anyone put anything in their doors/cab to reduce outside noise? I used some type of rubber insulation in my jeep a few years ago. I swear it was made by 3M, but I can't find it anywhere. Any other brands/types that anyone likes?

I put Dynamat Extreme from the back window to as far up the firewallas possible and doors. Quite a difference.

Thanks SmokinCigars! How much did you spend? Where is a good place to buy it?

I remember a thread that someone said they did there truck with a product that was just as good as Dynamat(believe they had tried both) and the price was way way way less.................Hoot mabey? Do a search and save some $$$

Here try this, its much cheaper than Dynamat car audio people swear by it.

I still suggest you use P&S in the link I posted above, but I understand if you don't want to put roofing material in your truck, still it works the same.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

not endorsing the deal, just posting as the ad has some decent pictures and the product comparison referenced on many sites.

I found a product on eBay called Fat Mat. It's specs were almost the same as Dynamat Extreme but the price was about 1/3 if I remember correctly. They were selling it for $100 for 100 sq. ft.. I haven't gotten any yet though.
