its basically self explanitory, dynamat your trunk, if you get the cheap stuff its half as think (thus, half as effective) pull all your carpet up in the trunk take out your spare, jack, all that good stuff. and just lay it on, cover the whole bottom. some people use a roller, some use their hands, the better its on the quieter it is. Just be careful that stuff likes to cuts up hands.

dynamat is probably the best idea but i have seen others use rubberized undercoating and love it. they even sell the coating with sound deadener. you can buy it at autozone

edead is a better bet..you get mroew fo it and it's performance and quality is just as good as dynamat..

when you buy dynamat, you just get a large thick sheet,

edead if applied properly and with a roller, will work and srve you well,

i have edead on my car and works great

As far as a DIY. . . Home depot sells a 4 wide roll of rubber for About $50 its 1/8" thick. With two layers of this stuff (stuck down with contact cement) its just as good as dynamat and a lot cheaper. (plus no worries about cutting up your hands

I used sound deadner from the spray can in my 280z with a straight piped 2.5 inch inline 6. Its really loud and the spray helped alot. Plus a can is only like 8 bucks.

I used 24 or 36 (cant remember) square feet in my Integra - that did the insides of the front doors twice, and one layer around the sides/rear. I did not have enough left over to even start on the hatch, and I didn't use any on the floor. Square feet get used up quick in a car!


I vote edead. I haven't used it yet but will surely be ordering some off of ebay after xmas. Dynamat xtreme is what was in my teg, and it worked pretty well. Your best bet is to buy as much as you can afford reasonably - and layer the stuff. Better to have some "leftovers" to help track down other rattles than to not have enough. I don't even have my system installed yet and I can already hear my license plate rattlin around just from driving!
