Everyone of you need to check out this REVIEW of nearly all sound deadening sheets that are made.

Totally agree with you redgst97
I did a whole lot of research before sound deadening my car. I had rattles on the deck with the stock bose subwoofer so you know that if I went with anything more it would be horrible.
Countless nights of looking up product reviews, customer feedback, then comparing prices to the quantity and quality of material took forever.
Reading up on which had the most (mm) of deadening I finally finally decided on Damplifier. It was the best bang for the buck.
The few sound deadening products I considered were: (In Order)
Sound Deadening Sheets
Cascade Audio - VB2-HD
Second Skin Audio - Damplifier / Pro
Dynamat - Dynamat / Extreme
Elemental Designs - Edead V1-SE
Stinger - Road Kill
Liquid Sound Deadening:
Second Skin Audio - Spectrum Sludge
Elemental Designs - Edead V3
-Cascade Audio really was my first choice, but their products even though well made were a bit too much for my budget and harder to work with. For the VB2-HD you will need a heatgun to apply the product. Unheated it resembles hard vinyl. Which is why I still have an unused roll.
-Dynamat and Dynamat Extreme were just overly expensive for the amount of deadening you received. Good quality material though.
-Elemental Designs was the cheapest of all, but sometimes you do get what you pay for. The material was very thin and can be compared to asphalt roofing sheets.
-Stinger Road Kill didn't offer enough sound deadening in bulk and hard to find other than on Ebay. A well known company in the car audio scene so I believe they have a good product.
I have looked into buying liquid sound deadening, but it is just a bit messier than using sheets. You will need to air out the car so that everything dries. I do have some Second Skin Spectrum Sludge, which I have not had the time to test out. So I will add onto this post later once I do.
Searching E-bay prices weren't low enough for sound deadening products. Once you added in shipping prices compared to the brick & mortar stores it was nearly the same price plus don't forget you have to wait on shipping.
I was VERY tempted to buy RAAMAT offered on E-bay for such low prices. Until I read the review I posted above, oh and read feedback about the smell.
What you have to watch out for with MANY of the other companies other than Dynamat is that they sometimes advertise that they are butyl based. In turn they really aren't and turn out to be "asphalt" based which once it gets hot makes your car smell like...well...asphalt. So keep that in mind.
Second Skin Audio is a small company based out in Arizona so their products have to withstand a lot of heat. I was interested in the fact I don't want my deadening material peeling and falling off in the hot GA summer.
Their prices are very bearable. I spent about $300 for over 160 sq ft of dampening material along with 50ft of their Overkill Pro line of foam dampening.
Customer service was awesome, and if you ever get to speak with Anthony himself he is a great guy. He has a lot of tips if you're just starting out.
Best of luck to anyone trying to get rid of those pesky rattles
PS: Don't forget to wear gloves. After 6 hours of working on deadening my hands were sliced up from the aluminum backing.
