Dynamat worth it ? - quoted $450 from audio shop

Then I have the weight of both.


When I originally installed it I laid down a nice layer of Plastidip for a few reasons, I figured it would "fill in" the gaps where I couldn't lay down the GTMat, it would be a 100% layer without air pockets and such, and in case I ever had to remove the GTMat, it would be MUCH easier with the PD... (The way these sound deadened work is by taking away or minimizing tibre [someone correct the spelling] so the trunk is like a drum, and this is rubber absorbing the vibration. PD is rubber to absorb more vibration [in my mind])

Glad it paid off, now I'll take off the GTMat and lay down a new layer of PD then put the foam on the PD.

The foam weighs next to nothing. It's 1/8" thick and self adhesive.

Very true, but I think the dynamat might be redundant with the foam

Not at all. Here's a better explanation from the website I got it from:

" this works in higher frequencies to reduce reflections by breaking up, diffusing the energy, decouples vibrations, and is a superb thermal barrier.The only place to limit the use is behind speakers, just use a patch 8x8" or so to break up the back wave, it is so effective more will just kill off the midbass response which is not what we want to acheive."

I've done cars with just dynamat, and the Z with both. It's by far better with the foam.
