For you guys with coupes, how many square feet of sound dampening material is required on the doors alone? I'm talking about covering most of the doors with sound dampening. Any ideas?

 

I would estimate 12 sq ft (6 each side). I am doing my install this weekend - so will let you know. I got the 50 sq ft roll of "B-quiet ultimate" as I wanted to do the trunk also - should have enough to layer it on now... (if you lived near Chapel, Hill NC I would split it with you - along with the cost of course!)

 

hey we both had exactly the same # of posts (now I have more!!!)

 

How much did you pay for this material you are using? I plan to get some from Elemental Designs called "eDead" dampening material.

 

the price is posted on the www.b-quiet.com site - I think like $129 for the 50 sq ft of their best material (equivalent to Dynamat's best by all accounts, but about 1/3 to 1/2 cheaper).

 

I had dynamat installed in my doors & trunk - great stuff. I also got the b-quiet hoodliner, which installs in like 5 minutes. Get either one of these "brand" names, don't risk it with something like eDead that nobody has ever used - this is too much work to have to do twice.

Just my 2 cents

 

You can get a Bulk pack of DynaMat Extreme on Ebay for around 80$ I believe it is 32 sq ft. I used 2.5 bulk packs still had rattles, until using some spray foam..

 

i've never done this before, and i was wondering what the trunk looked like after it was done. i'm about to do my audio, and really don't want my trunk rattling too much....but at the same time i don't want my trunk to look like it's lined with aluminum foil either. any help would be appreciated.

 

The carpet will hide the Dynamat inside the trunk, and I only applied it to the area on the trunk lid that had the grey liner, so that hides it. I have a Diamond Audio 10 M6 sub powered by a 600 watt amp and I hear absolutely no rattles coming from my trunk.

 

thanx sooner...

Awesome writeup man

Id love to sound deaden but I really dont want to take apart the whole car; I had enough fun taking apart the front
Definitely if I ever upgrade the stock Bose though; might as well since the door panels are already off
