Dynamat install (long)...
I completed my Dynamat project over the weekend while installing new window guides in the front doors.
Dynamat is a sound deadener used by the car stereo industry to decrease interior noise and increase the sound quality of car stereos. Its also good for reducing road noise and exhaust drone. Dynamat consists of a thick aluminum foil coated with a layer of asphalt sound deadener. Its available at Car Toys, Best Buy, etc. However, its much cheaper if you buy it online at a store like carstereoonline.com. There are also many alternatives available. Do a Google search on Dynamat and you'll find plenty of alternatives listed.
I started by doing the spare wheel well and trunk deck. The wheel well and deck can act like a giant speaker. Applying Dynamat here can make a significant change.

This did quite a bit to take the edge off of road and exhaust noise. I then did the rear wheel wells, under and behind the rear seat, and the floor boards. The front and rear seats come out easily and has been documented multiple times here (thanks to BD for his great write-up on removing the front seats). Lifting the carpet involves removing some trim around the doors and is fairly easy and straight forward. All-in-all, I found this to be worth the trouble. The car is quieter and the stereo sounds better.
The final segment of this story was the front doors. Following the excellent write-ups in Stoney's FAQs, I replaced the window guides for the front windows - 1 was broken, another was on its way. While the door was apart, I applied Dynamat to the doors.

In the before picture, you can see the stock sound deadening material. I was actually suprised to see it, as many of the A6 doors I've seen don't have any. In any case, I applied Dynamat over the stock material. Its a little early to tell, but it seems that the door closes with a more solid feel now and that the front speakers sound better.
IMO, if you're interested in improving the interior sound quality of your car, this is a good way to go.

Oh, I hear ya, and that's not too bad at all...
I just know that every time Dynamat gets mentioned, people talk about how heavy it is. 10-20 lbs on 3800 lbs is nothing and it wouldn't concern me in the least. Based on internet lore, I thought you were going to reply that it weighs 100+ lbs!
For the improvements in sound and sound quality, it sounds like a winner to me... :>

Very nice... been thinking about doing that on my car. Any special tools?
How did you get the material to stick? Also, on the doors, did you take care of the front and rear doors?
Come summer time, I might do the same on my car. Depends how the new set of summer rubber sounds compared to the thunderous SO3's that I run now.
