Dynamat worth it ? - quoted $450 from audio shop

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.

Yeah I'm pissed about that because their Onyx line seemed to be a pretty decent product. I did my hatch, but haven't done anything to the doors yet.

DEI's Boom-mat is cheaper than Dynomat and just as good.

+1 on Boom-mat. Works quite well in the back of my Z

+1 for dynamat... for no reason.

This is definately an easy DIY. Most of the cost is labor so just take an afternoon and do it yourself.

I got Buzzmat from my stereo installer and put it in myself. Then to top it off I stuffed some Roxul Safe'n'Sound into the voids behind the plastic trim. It made a huge difference. I only did the trunk and it good enough for me. If you do the work yourself it is easy enough to do it in steps till you decide what it is good enough. Don't however expect to get Lexus or Mercedes level of silence in your car it ain't going to happen.

My logic on the mat is acts as a deadner(dampner) to reduce the vibrations coming thru the skin of the car and the Roxul acts as a sound absorber. Anyways all I really know is that when I run through a puddle it dosen't sound like the water off the tires is coming right into the cabin now.

I would guess that whether you use Dynamat, Buzzmat, Boom-mat or whetever I doubt you could tell the diffference. they are all more or less the same a tar like substance on a foil backing.

I could probably still get you a decent price on a few sq ft for the doors if you want it. I'll be dropping by their office at the end of December.

My Nismo rear hatch is all covered with dynamat from previous owner. So much quieter than my yellow touring Z. I guess it does work.

In my years in car audio, $ for $, better off spending on amplification rather than on damping material.

Damn the passenger must be pretty special for you on to want to talk to them

Today is judgement day - I'm hoping I'm not making a bad investment - I think $250 is worth it bc my wife is paying for half for Xmas. It was this or stillen gen 3 - I'll wait to get gen 3 when I get my bonus in jan. Will see fingers crossed
