Thanks,

RAAMmat BXT is good stuff. Doesn't stink when it gets hot. Call Rick, he is a vette owner, (or was) and sometimes offers great deals on leftover rolls, etc....

 

Having only installed one type/brand there is no basis for comparison. Only an opinion of how satisfied I am with the results, which is about all anyone can offer.

I used the package from Exoticvettes along with their rear divider. Not only did it reduce the noise level considerably, but the cabin heat dropped too. It's still not as quiet as my Caddy STS, however it's a whole lot closer than before.

The only downside is that now with the bi-mode exhaust closed, I can hear every single word my wife utters. Of course, being a man allows me the option to use the selective hearing defense I get blamed for anyway.

 

BUMP... Wanting as many peoples advise as possible..

 

You have to use several different types of sound deadener. The sound frequency are at different levels. I have used several brand over the years and prefer second skin, give Ant a call, great customer service. I would do it all at one time. The disassembly is most time consuming. Check out some audio sites. http://www.diymobileaudio.com/forum/
Here is my vette install.

Check out Cascade Audio. IMO the most complete line of product out there.

 

There are a few great products on the market and some not so great, Dynamat Extreme, Second Skin Damplifier , RAAMmat BXT II, all close to the same in performance so what it really boils down to is doing a good install and ease of use!

(Though Harmon International, they own Infinity, JBL and many other brands, now use BXT II exclusively in all their projects because they love the price/performance/install ease

If you read the HOW TO guide on RAAMaudio.com, written for our older BXT which was less effective but much lower in cost than those above, the shotgun approach for the mat is called for. The products listed above are of such great effectiveness you can use much less but target the key areas and on the Vette there are very important steps to be taken.

My recommendations below are based on 40+ years of car audio experience, 20+ years in high end electronics repair in the USN, having competed against and beaten a prior world champ in SQ competition, having been an audio judge and knowing most of the top installers ever combined with 10+ years specializing in sound deadening (and I have two Vettes and helped dozens of owners achieve their goals

------------------

Doors, at least half the outer skin, focus more behind the speakers, covering most of the area with a second layer around 8x8 or so right behind them. Put some strips, 4"x15 or so towards the middle and rear of the door. Then put a piece of Ensolite (sold under different brand names for much more than I charge behind each speaker to break up the back wave, I find this just as effective as a costly Deflex pad and even used it behind a $7k pair of separates mid basses just fine.

I like to use a solid piece of metal to fill in the large access hole, this will greatly reduce road noise and stiffen up the air space for more accurate and more output from the speakers in the doors. The seal all the other holes in the inner door and mat well around the speaker. Then cover it all with Ensolite or similar, it is an incredible thermal and acoustical barrier, low in weight, low in cost, helps stop panel resonance, etc and works in higher frequencies than mat products. Ensolite nearly doubles the results of just mat alone, no matter what brand.

I may offer some aluminum channels for those that want to really go all out and stiffen the door more without the added weight of using a lot more mat, what I did in our car, worked great

------------

The hatch area is the next most important. Completely cover the wheel wells and then the middle of the rear deck, then strips along the sides, etc....I add a second layer in the middle of the deck area. Cover every thing you can back there with Ensolite, it helps keep a great deal of heat out as well

------------

Behind rear seats up next. Very thin sheet metal there so I cover at least 2/3 of it with mat, centered in the middle, cover it all with the Ensolite.

------------

Tunnel, more heat than noise issues. I use strips of mat to cover around 40% of it then cover it all with ensolite, double up onit near the shifter, etc.....

------------

Floor, not to critical in these cars due to the balsa construction. I have yet to even mat mine but will do some soon to see that happens and then cover it all with Ensolite.

------------

One package of our BXT II, 3 yards of Ensolite (glue down or now we have some Peal and Stick), will do a very good job if used very carefully.

Really want to do it well, 1.5 packs, 4.5 yards, etc......

------------

No matter what brand you pick, the guide above will help you greatly. Just make sure to take your time and absolutely use some sort of quality foam like Ensolite(the very best I have ever found)

------------

As soon as I get a volunteer I am going to produce a Vette specific guide with pictures, I would use my install but I went all out nuts on it as it is our audio demo vehicle and I have a tendency to go all out nuts. I need to make a guide that will take care of 99% of those not as **** as I am because like all things there is a point of diminishing returns.

------------

Purchase from me is not required to get help if you need it but read my HOW TO guide and this before asking please
