Sound Deadening Mat

[emann_01]

I did a little bit of searching and was astonished to find that our forum does not have any threads reviewing sound deadening mat!!!!???????????

So please provide your thoughts regarding sound deadening mat:

...quality compared to price?
...ease of installation?
...raamat, fat mat, dynomat, or whatever you have used?
...how much is needed to do the all doors, floor, roof?
...good place to buy?
...any experiences are appreciated


I plan on doing this soon to more than just the Tahoe so any input would be awesome!

Thanks in advance!

there are really no cons, all pro's....brand, all are very similar to a point, up to user's brand of choice.
We've always used Dynamat

 

[emann_01]

also I have heard different things about sufficient coverage...25%, 50%, 100%, multiple layers???

any thoughts?

 

[blueflamed03]

depends on how much you wanna spend too...and how 'quite' you want it

their is alot of talk of this at a website called caraudio.com. search deadener and you will be surprised. Im pretty sure the brand of choice is raamat, they have awesome product and its butyl based instead of asphalt so it holds to higher temps better and is thicker. Coverage is also disputed, id recommend just doing it all since you're going to have it apart. I put 100 sqft in a blazer i had, and all i did was the doors and the rear hatch, but i did waaay overkill on doors. Its alll up to you though and what you plans are for sound in the car. I would highly recommend checkign out caraudio.com and diymobileaudio.net also. The latter is highly technical so it may be over your head, but both are great sites. Hope this helps!!

I use B-Quiet and really like it, usually always done in 2 layers for great results. You could probably get away with one which helps a lot but a second layer is equally so. It's cheaper than Dynamat which I've used and it's good stuff, just too expensive. I ordered all mine from either eBay or directly from B-Quiet, but for best prices check eBay. Sometimes sellers put their leftovers on there in odd sizes for extremely cheap which work great for smaller areas.

where are the best places to cover?

...doors?
...rear hatch?
...roof?
...floor board?

i thought i might get more input on this subject...

BabyHuey... thanks for the advice but i dont think it is over my head...

 

[Snipez]

IMO I wouldn't bother with the roof, at least not at first because the other areas will be more effective. From my own experience the best locations to start with were the doors and the floor board, anywhere you can get to easily is what I would start with. If you want to just reduce road noise the floor and doors work wonders, to chase after rattles especially from a stereo you'll have to dig around in more hard to reach places especially towards the back ie hatch area.

Not trying to hijack this thread, but anybody ever messed with liquid sound deadner? Found this on eBay:

I didnt mean that sound deadening is over your head, just some of the topics over at diymobileaudio can be over your head. Some of those guys use way to big of words and complicated theory when it comes to audio

The biggest places you get rattles from are spots that are the flattest. And akuma, liquid deadener is also good, it works well for spots that are hard to reach or are complicated bends. It can be messy though, most people put it on with a sprayer or with a brush, but it has its uses for sure.

anyone heard of or used Second Skin Damplifier?

what about the sound deadener you can supposedly buy from Lowe's or Home Depot? (not the crappy tar paper stuff)

 

[BabyHuey]

Second skin is the best that ive heard of.
Dont know what deadener they have at lowes, all i thought they had was the tar paper stuff. That stuff makes ur car smell horrible for awhile.

 

[Snipez]

Home depot used to have some that was 100% butyl rubber, at least the ones around me did. I used it once and it wasn't bad. Wasn't very thick but it was cheap and if you doubled it up it was great, I don't know if they still have it as it was a year or so ago. They also have the roofing felt, not really the paper stuff but it is a similar product. Lots of people use that if you read around the net, seems to work okay.

 

[emann_01]

anyone used or heard of elemental designs edead? edead 80 is $2/sqft and edead 45 is $1/sqft...price is good but just wondering is anyone has opinions of it?

[Snipez]

eDead is good stuff, some of it is pricey but it's all good nonetheless. I actually really like the v3 stuff, dries fast and no smell. Needs multiple layers but is so easy to work with.

...quality compared to price? I've only used Dynamat. I still think this stuff is overpriced but it works great.

...ease of installation? Piece of cake. Razor Knife, Wood Roller and a Heat Gun

...raamat, fat mat, dynomat, or whatever you have used? I've only used Dynamat

...how much is needed to do the all doors, floor, roof? If you are looking to stop rattles and tighten things up a bit, a two door Dynamat kit ($50-$70) will do four doors easily. If you want to block outdoor road noise as well then the two door kit will do two doors.

...good place to buy? Online but look for shipping prices as it is heavy. I got my last batch at Best Buy on an open box so it was almost $30 off for the two door kit.

...any experiences are appreciated.
*Clean the surface well.
*Get it warm with a heat lamp or heat gun so it's pliable.
*Lay it on flat and then roll a wooden roller over it to flatten it out, lay in the crevices well and get it to adhere well.

^ now thats an awesome reply to the OP...thanks!!!

 

[VikingFan]

lol. Glad it helped.

I've known people who have stripped the inside, taped things off and then had "Duraliner" sprayed throughout with fantastic results. Again a bit high in price but it's an option.

 

[Snipez]

Well the rest of us tried, lol.
