I used Second Skin Damplifier Pro in the whole back area, under the seats, behind the seats, the tunnel, the doors, the ceiling and the hood. A lot of work, but I'm extremely happy with the results. Here are some pics.....

Wow, I'm surprised. I was going to suggest Second Skin as well, but I figured most of you wouldn't recognize the name.

I did my whole car and most want go this far but this is what I used:
Sound proofing:
Damplifier Pro 150 sq feet
Luxury Linear Pro 5 Sheets 40 sq feet
Speaker Pads 2
Overkill 9 sq feet

I bought the "Shop Pak" and the "Door Pak". When I had a number of sheets left over, I used them on the Rear Roof Bow (on a Coup) and the Hood. So, to answer your question, probably about 80 Sq-Ft, but it's better to have too much than not enough to finish the job.

The important question. One of the reasons Corvettes don't have a lot of sound deadening is because they are lightweight sportscars. I'd hate to add a ton of weight to the car.

honestly I am not really concerned about the added weight.. If it slows it down some I will do a couple of mods to speed it back up.. It is my everyday car and I would rather it be more comfortable than it is now...

I did the same mod in my C5, I followed Mike Mercury's writeup.
http://mikemercury.home.att.net/sound.htm

This was $17 a roll, I used two rolls to do the entire trunk area. It looked just like HuskerBullet's trunk. I got it from Lowes, it's dense foam with a sticky backing and topped with thick foil.. I'm very happy with the results! It made a huge difference with the exhaust noise, no longer does the exhaust sound come from the trunk.

The good stuff is 0.5 lbs per sq ft so, realistically, you'll be adding anywhere from 40 to 80 lbs to the car depending on how crazy you go.

Since you decided to bring up an almost 7 year old thread without actually offering any helpful information, would you care to elaborate a little?

What is wrong with the posted techniques and/or materials?
How would you do it different?

I'd be interested in quieting down the interior a little.
