Mike,
It looks like he hasn't seen your Frost King write-up. If it's been a while since it was posted you might want to re-post it so many of the newbies can learn about it.
I did the Frost King mod on my 02 vert mn-6 over a year ago and it really made a big difference.

I found Mike's post after someone mentioned it in another thread. I did it about 3 weeks ago. It made a huge difference in tire noise.

I have taken the picture with my digital camera, but you need to have it hosted on the wb in order to show it here. I have submitted it to Corvette Forum for hosting, but they review each photo before hosting it.

I actually kept it at the top of the storage wells. I think it would be more effective at the top of the wells as there is no "free volume" of the wells to resonate.

I was the guy that asked Choreo about his mod to begin with.This foam sound deadening material looks pretty good, and at $2.00 a square ft, it can't cost more than $20.00 to do all three rear compartments.It should stick to the underside of the covers, it's thin, very lightweight. I would not want to put fiberglass batts inside my car.With the top off, or even the windows open the air movement blows fibers around.READ the information about fiberglass. IT IS NOT GOOD FOR YOU.You don't want this stuff getting on you or in your eyes or lungs.I'm in construction, and I always read the warnings on material packages.Even though the fiberglass is inside the compartment, every time you open it, fibers get out, and they would get on anything you store there. Any kind of closed cell foam, especially one that is designed for sound deadening properties is better. Protect your health and the ones you love. Maybe one of the engineer tech guys here might be able to supply info on sound deadening materials and specs.

You say you never access these compartments, but also say they are not quite full of stuff either? I just can't see having batts of fiberglass in my car, let alone losing that storage space. But if it works for you, that's all that matters.: thumbs:

Although the fiberglass batts work great, I have ordered some 3 inch thick coned foam sound insulation at:
http://www.foamorder.com/acoustic.html
It should make a much more professional job and be easier to live with.
It was about $40.00 with shipping. I will put this on the backs of the panel covers. I will report back on it's effectiveness.

I rarely (3-4 times in 3 1/2 years.) go into those compartments, so I gave it a shot this morning. I used 3 1/2 inch thick insulation (I'm also really cheap, $11) under the lids and Lloyds mat, and behind the divider. It does make a noticable difference. Now the tires seam louder, but the other road noise is less. Good idea.
P.S. With the paper side up, the covers secured, and a heavy mat on top, I don't see how the fiberglass is going to be blowing all over the inside of the car. In fact, I don't see anything coming out of those compartments unless they are opened and the fiberglass is disturbed.

I too notice you can hear some noises (tire and wind) that you didn't hear before. But let me note, the overall noise is greatly reduced and the tire noise is much less than the "road noise".
I too rarely open those compartments, but my car is my "pride and joy" and if I had to open those compartments it looks rather amateurish, although it WORKS GREAT !

The link I gave you is used by many sound audiophiles as a cheap way to keep out A LOT of road noise. You can also layer it!
