Dynamat Question
Hello Forum Members,
Has anyone ever tried Dynamat or any other sound dampening material? I'm curious as to whether or not it really makes a difference in sound quality of your audio system and decreases road noise? They advertise it a good bit in the audio shops around my area. I know the real Vette experts will have a "TRUE" opinion of this stuff. Thanks in advance for your comments.
Thoughts?

It makes the car feel more "solid". I had it in my 08 Coupe. It keeps the cargo compartment cool, it did reduce tunnel heat on the 08 and noise from the rear fronts.
Drawbacks - Parts don't fit as good as w/o it. They are designed to be a little loose to adjust to temp changes. It amplifies the front tire noise though.
I have no desire to put it in my 11 GS Vert to be honest. There is no tunnel heat as it looks like GM put some insulation there. I don't want to amplify the minor wind noise from the top. I may put it in the trunk just to keep things cooler back there but I believe if something is not broke then you don't fix it.
I love the Corvette but if I want a quiet luxo cruiser then we'll take my wife's new Chrysler 300C Luxury Series. You can barely hear the Hemi or anything that resembles road noise. The Vette never will be nor do I want it to be that quiet. She actually likes the NPP open all the time (even with the roof up) because it sounds "sporty".

I put 3 different layers of sound/heat insulation in my car, including the doors, when I was installing a complete sound system upgrade. It definitely makes the car feel more solid. It cuts out the majority of road noise and a lot of the heat too. Now I can really enjoy my sound system when I so desire.
I can also still enjoy my dual mode exhaust as well though.

Which Corvette do you have? I'll guess you have a coupe (removable roof panel).
Anyway, there are lots of strategies for noise reduction that don't require disassembling the interior:
1. Isolate the cargo area with a partition. The partition also better-directs the sound from your rear speakers. And it gives you a handy shelf.
Lots of choices & options for a partition; I got mine from Exotic Vette: http://exoticvette.com/C6%20partition.htm
2. Easy-install BLOCK-IT: http://forums.corvetteforum.com/c6-p...e-special.html
3. A Lloyds cargo mat helps reduce noise. And it looks good.
4. Poor Man's Sound Deadener: Bedding/blankets in the cargo area, beach towels in the passenger footwell.
5. A routine maintenance lube will help keep your roof panel quiet:

6. When you need new tires, some are quieter than others: http://forums.corvetteforum.com/c6-c...e-2008-c6.html
7. If-You-Don't-Mind-The-Work: Some folks have disassembled the interior and installed Dynamat or similar products. Do a search, lots of threads like this:

Seems like a lot of work to me. And it's not my idea of a mod for a sports car. But if I was going to do it, I'd pay extra for a pre-cut product... here's one that includes detailed installation instructions: http://www.exoticvette.com/insulation%20c6.htm

Thanks guys...this is helping make my decision. Yes, I have a GS Coupe. I'm just hoping for something which will allow me to make a call on the bluetooth while driving. Don't get me wrong, I love the sound of my Borla ATAK so mainly just trying to improve radio sound, decrease road noise a little (primarily for the wife) and utilize the bluetooth.

If you're going to do it, do it right, and efficiently. 50% coverage with a dampening material like Dynamat to keep the body panels from introducing noise, and then 1-2 layers of a sound barrier like Ensolite to prevent external noise from entering the car.
Dynamat and similar materials aren't designed to block sound. They dampen the vibration of panels like the huge plastic tub that forms the rear cargo area, and the big outside door skins. They will block sound if you form a 100% barrier, but that adds 2x more weight than necessary, and costs 5x as much as using a closed cell foam like Ensolite which kills vibrations travelling through the air.
Find Peel and stick Ensolite (a couple of the forum vendors sell it), and you'll make your job much easier... No precut needed. Cover everything completely - otherwise it's like closing 2 out of three windows in a room... Most of the outside noise will still make it in.
