Sound Deadener?

[bliss_creator]

Hi guys,

I am upgrading the whole sound system and looking into sound deadening materials. Looking up I found two types,

1. Dynamat ($135 for 36 sq.ft)
2. Fat mat - ($130 for 100 sq.ft)

Any opinions and how well the fat mat works? or any other suggestions?

The dyanamat extreme bulk pack will be enough to lay down for the trunk alone, wont be enough for the doors and the insides, any other suggestions?

I used Edead online, and the Home Depot roofing stuff.

Looks like some quality stuff, I can't be the judge since I've never purchased it, but it's cheap!

Do your homework... Fatmat, Dynamat Original, eDead etc all are asphalt based products. You need a heat gun to apply asphalt based products and they still come off your car panels after sitting in the sun. Do it right if you are gonna do it or don't do it at all.

You want a butyl backing. This adheres much better, withstands higher temperatures and adds mass correctly. The thicker the butyl backing...the more mass you add to your panels. Thus reducing vibration and so on. The thicker the aluminum shell, or barrier, the more it will keep out heat and reduce flex.

The thinner the dampener, the more layers you will have to add to have the same efficiency. In my experience it is cheaper to do it right with 1 thick layer and cheaper too. I think Damplifier Pro is the best. Dynamat Extreme is second...a little thinner (not audibly thinner) and a lot more messy. Stinger has some that's good and a few others I'd recommend. If you are looking for a noise barrier then plan on spending MORE money.

my fat mat has been on for about 2 years now and hasnt came back down

fat mat = generic...very thin
edead = cheap...very thin. doesn't seem to have a real foil backing, more like a foil-coated plastic
dynamat = ok. the extreme is preferred...dont bother with original
damplifier = thick, sticky, best performance for the price.

also check out don's site http://www.sounddeadenershowdown.com/ it'll give you a new perspective on dampening.

btw...why are you going with 2 6.5" component sets? that XXX mid is going to suck to make a kick for. why not use the 6.5C set in the kicks, then try to squeeze an 8" mid into the door?

well if youre just going to use the stock passives i guess that wouldn't matter as much to you...

Do not use fatmat or any similar sound deadening.

DynaMat is great stuff, but its like buying Mugen or Spoon parts, you can get other similar products with the same quality for cheaper.

My recommendation would be second skin damplifier pro. This stuff is simply amazing. I have been using it for a few years now since it came out. Ive tried almost every brand of sound deadening out there and this is by far my favorite. It is a little pricey, but not as much as dyna mat, but its a great product.

If you want to go a little cheaper, look into raammat http://www.raamaudio.com/

If you have any questions, feel free to shoot me a pm

I've used raammat in the car and truck as well as many different products in the car. I can say it's great stuff, but I have heard many good things about secondskin stuff. I'll try some out on the next go around or big install that I do. It's a big help but I would make sure that you put it in the right places to get the most effectiveness.
