Dynamat, Anyone done it? Options

[PowellCelica]

I realize more then a hand full probably have but i'm looking for a wright-up or something. Or just some picture of it being installed. Where did you put it? How much of a diff does it make speaker wise? Road noise wise? Engine wise? And even closing your door? I'm really looking at doing this because i personally can get this stuff cheap through my friends shop.

I've got a bunch of stuff that's exactly like Dynamat Extreme, but without the Dynamat logo and the outrageous price. I've got about four to five layers on my trunk lid and underneath my rear deck. On top of the rear deck and on the side walls and bottom of the trunk, I've got two layers, and on the back wall of the trunk, I've got about three layers. On the front doors, I've got a layer on the backside of the door panel, and one on the inside of the door. It has made a huge difference in the way my car sounds. No more rattles, and you can hardly hear my system outside my car.
