we researched it and found something almost identical that you can buy at your everyday Home Depot/Lowes

its dirt cheap and works :) brother did it to his trunk about a year ago.

5th gen problem area for sound is not the trunk floor. Its actually the rear quarter panels, between the door and the fender well. Take out your rear paneling and speaker assemblies. I used expanding foam in the "seams" of this area and used Brown Bread (same as dyna mat) on the rest. Make sure to get the expanding foam to go right upto the top of the curve in the fender well or the whole process is useless. You can also put dyna mat like material under that material covered panel on the upper deck in the rear windhseild. That way, with your seat up, your cabin will be noticeably quieter.

If you want to go right to hell with it, remove your seats and carpet and cover the entires floor area, leaving only the necessary holes exposed, do under your rear seat as well.

Also, you can remove your door panels and cover the door area as well, making sure to cover the original access holes in the panel ( you can cut the dyna mat out if you ever have to get into the actual door assemblies).

Totally crazy ? Remove your headliner and do the roof, then lastly, cover your trunk top, sides and bottom !!!

Your car will be 200lbs heavier, slower, harder on gas, but damn, it'll be quiet and smooth !!! Mine is

Ok Just did more than half of the wifes little car. I like it! I will be ordering more for the celica this comming week!
I put this stuff in in about 55-60 deg temp and it stuck with no problem. I did the drivers door and had a really nice improvement of lower range in the 6.5's I have installed powered off of the deck! I will do the passenger door tomorrow and take some pics of it. Here are some of the cargo area and under the saet.

I have to say, A deck and 4 speakers has never sounded so good to me! The bass is soo much more clean and tight! If I didn't know I would think there was a 10 in the front of this thing!
Without the stereo on it is much quieter in the car! A++ for this product!


P.S. I am moving this to General.

Why would you?
The idea is to put it in and leave it. :)

if you DO need to remove it use liquid nitrogen and a pick
