I am thinking of sound proofing my Vette and wondered what some of your thoughts were about doing this? Thank you!

I think Mike Mercury has the actaul numbers, it's pretty heavy! He and I both used Frost King, lighter and cheaper but not as good as Dynamat at noise reduction but does offer heat protection around the shifter console.

Tim, did you also put in the thicker aftermarket tunnel plate underneath for added strength and heat protection into the driver area?

Hey Ron!!!!

No I haven't, I decided after the Frost King killed the heat so well that I didn't need it just for the extra rigidity it offers... If I tracked more often I would've gone that route!

Excellent point bringing it up though... :thumbsup3:

Frost King is a spray? Or no? I know dynamat is "fun" to put in of what I've heard!

Dynamat is really great. Used it in street rods with great success. It is heavy but oh so effective for noise.

No it comes in rolls and is self adhsive to a point...

Dynamat is good, but it'll add 70 lbs ... and that's without doing the doors.

I applied Frost King to the entire interior (except for the doors) using 5 rolls... it weighs 3 lbs per roll; 15lbs total.

If added weight is not a concern... I'd use something denser (Dynamat Xtreme, Quiet Zone, BrownBread...).

The kicker is that dynamat and other deadners funtion by increasing the mass of the panel they're attached to. The heavier they are, the more effective the deadening.

This beign said, i'd check out second skin audio's damplifier and damplifier pro. It's less expensive than dynamat and had superior deadening charachteristics:

I was sent samples of D'amplifier Pro for evaluation. It was denser than Dynamat Xtreme, and handled heat better... and was less expensive !!!

It's still heavy though - if that's a concern.

For reference purposes: A full tank of gas (18 us gal) weighs roughly 115 pounds.

My sound system (sub, amps, amp rack and sub box) add about 150 lbs. This weight is strategically placed mostly over the rear axle giving extra traction to compensate for the weight gain.

Have a friend that has a competition stereo setup in his pickup and he used a ton of dynamat in it. But he is not going fast so weight means nothing to him.:thumbsup3:

I know alot of the guys that have the APS turbo systems are using it to battle the heat!

Dynamat has no heat reflective properties... a good cheap product for that would be Reflex ( I think it's called) sold in home centers where The frost king stuff is sold.

:iagree: Reflectix is much better suited to insulate against heat than FK or the Dynamat products.

wow what an informative post. Maybe you should get a job, lol.
Thanks for all the great info.

You mean we should get a job? Then who would tell you all this cool stuff?

The problem I have is more road / tire noise than exhaust noise.

So then..... D'amplifier Pro or Dynamat would be a good investment for sound deadening, right ?

There are several options really, Just filling the cubby holes in the back with something absorbing like a roll of insulation will kill ALOT of noise. If it's just tire noise you can take off the rear inner fender well covers and line that whole area behind them with a sound deadning product and also stuff insulation up in front of the gas tanks. Also a partion helps alot...

I'm going to do this with FK in the spring when I do my major clean up on the car...
