Sound Deadening/Vibration Dampening....

[XxApollynxX]

Alright, I'm sure there are some other people on here that have used sound deadening or material to stop vibrations from either subwoofers or from exhaust etc.

I have normally used Dynamat Xtreme with very good luck, but its very expensive, and some times takes a lot to get the job done.

After googling I see fatmat, hushmath, bquiet etc.

What all, has every one else used in the past with some good luck? I've seen some people say you can go to home depot/menards to buy some sort of roofing material that looks like Dynamat but im skeptical, looking for first hand results here.

People love this stuff. I never got around to actually getting any but from all my research it's what a lot of people end up using.

I actually had a thread about this somewhere on here.....

My Gtp is done entirely in something but it sucks. Iy falls off in some places and can smell. I can't remember the name tho

How much weight does this stuff add? Isnt a roll like 75 pounds?

I always found this websites approach interesting as opposed to just covering everything in dynamat.

That test was done by whatever company won iirc

Makes sense seeing as he now sells his own.


I need to get on this and put some in the back of my car. Wagons sound like a tin can inside

my gtp is done like this. whole roll was around 60lbs. idontgiveashit.

here is a quote from cgp from 2008 when i installed it all

differences i noticed between this fatmat rattle trap and dynamat was that this stuff (fatmat) is not as easy to move... doesnt bend and make contours like dynamat, it does it, just with more persuasion. Also, it does smell, it is for surely asphalt based, and leaves a good stink upon application, and when the car heats up, but now it is barely there, if at all.

as for performance, when i dynamatted my lumina, i only did the trunk, and this time, i did the floor and a lil more of the trunk. so i cant really compare it, because it is sort of apples to oranges.

the stuff does work well though, and i got it for around 180 bucks for 100sq feet on ebay.

my car is muuucch more quiet, and my stereo, while strong but mighty, is much more clear and snappy.

i am definitely happy with the results.

I really like it, because windows, exhaust, sunroof- everything closed... my car is quiet as fuck on the inside. not like a new sl63 or something. but definitely the quietest pontiac i have been in

 

[Bob Kazamakis]

Did you use all 100 sq feet?

If I ever get around to ordering some I'd like to do the firewall, doors and rear hatch area. The front floorboards actually have a good amount from the factory but they pretty much stopped after the rear footwells.

 

[Yaj Yak]

Yep, used every piece. inside my doors, floor, quarters etc... i can be bummmmping in my car, and it doesn't make any rattle on the outside.

 

[Yaj Yak]

probably one of my favorite things i did to my car.

Oh I agree it isn't a review site anymore as he sells his product. I just always thought there had to be a better way then putting mat down everywhere in the car. Just put down the CLD pieces to stop vibration then put in the mass loaded vinyl for the road noise. Will probably use this in my Z as I don't want to put in a ton of weight into it especially the hatch if it vibrates with the new sub. The road noise/rock hitting the wheel well gets to be a bit much at times.

i figured 60 lbs was okay to trade for silence when i want it
