Thought I would try to contribute to the board instead of always asking - so here goes...

For those who don't care about weight, you can try roofing shingles instead of dynamat and other types of sound deadening material.
Get yourself a caulking gun with regular silicone and a hair dryer (not a heat gun, as tar loosens very quick and can get messy) and use it like regular matt. It can be removed if needed just about as easy as regular dynamatt. We use to do this in a stereo installation shop I worked at as a low cost alternative to the regular stuff, with no complaints. We would take the time to lay it out nicely, cutting pieces to shape , just like normal, and silicone them down. Then we would take large sheets of plastic- garbage bags cut down the sides make huge squares- and spray glue the plastic over the shingles. then put the carpet pad and carpet back over it. done deal. Shingles are thin, so sometimes we would lay 2 or 3 layers down to get the desired effect. Wear gloves because after all, it is tar. This works best for under the carpet on the floor and in the trunk, its a little easier to use reg. dynamatt in the doors because it bends a little better (shingles crack if bent and not heated enough).
I'm going to be using this on my first gen floor boards, and I'll have a walk through with pics on my site when I get around to it.
Good luck.

Sweet - Nice tread. More than one way to skin a cat, I guess. Probably a little more enjoyable to install to... hmmmmm
