which would be better and / or easier for the floor of a car, regular sound deadening or some type of truck bed liner (paint on stuff)? which type of truck bed liner is available or good in this application?

thanks

 

What I assume a deadener does (since it is an undefined term) is to absorb AND dampen ALL vibration/ and sound from the exterior of the vehicle (not to absorb internal sounds from the audio system.
The bed liner would make a pretty stiff product, and as such will change the chassis resonant freq (raise it) this could be a good OR a bad thing depending on the car and the frequency it is moved to. That is how it would affect the damping factor, it PROBABLY has a poor a STC so it would probably be inferior in transfering vibration to heat.
From a noise absorption point of view it would depend on how thick you put it on... and it really isn’t designed to absorb sound so its STC and Absorption Coefficient are undefined.

When I did the floor in my NEON I put down 2 layers of Dynamat Extreme the sprayed the harder to reach area's with dynaliner and finally I added a 1/2" layer of acoustic foam under the factory carpet. All were very easy to use and worth the price in the end.

 

I would use Cascade Audio Engineering VB4 on the floor, and that's it. Cut the sheets so you can put them in other vehicles too...

It's a lot less work and will accomplish more than the bed liner and Dynamat Extreme combined.

I have a <Little> experience with this stuff. [img]tongue.gif[/img]

eDead V1SE works great for me... 2 layers everywhere, 3 layers in the big flat spots... run silent, run deep.

 

i would think the off gassing would not be nice .
what is the set-up for ?
look at the rules for deadening
for the cost i would not do it [img]graemlins/dunno.gif[/img]

 

Eh. If you get roofing material it should be fine. It's cheaper in the end. All deading does is add weight and stiffness to whatever you are plastering it on. As long as it does the job, use it. Just make sure that if you're doing the roof that you use actual deading material so that the adhesive *shouldn't* flop off when it gets a little warmer

 

l-comp x 2, it decouples the floor from the pass. compartment...Every car I have done with it, has turned out awesome...
