Just got done dynamatting my passenger side door. Didn't take more than an hour or so, but god damn I got a crap-ton of cuts (small ones, like paper cuts) on my hands from the thin foil-like layer on it. Well worth it though. I used the Xtreme stuff which is pretty light weight and pliable (much nicer to install than original dynamat). Door closes more solidly, lots less road noise and vibration and crap. Speaker sounds more solid.
all this stereo talk makes me think that a wall of 15's may be in your future?? j/k are you using the real dynamat or the cheaper stuff?? My neighbor wants to get some done and is looking at the cheap stuff.
You guys want to know a secret? For $50 you can get enough mat to do 2 entire cars. At Home Depot they sell Weather Mat. It's basically the same stuff but in giant 20 pound rolls. It's made for roof insulation. With my old L I did the entire car including floor, ceiling, B pillars, trunk, firewall, and doors. Cost me $25 and like 6 hours.
i just dynamatted my volvo's doors today while i installed my new double-din headunit, coax's in all doors and my 12/amp combo. i would have rather used hushmat or raamat because of cost but the original will do, it just costs alittle more. sounds good though
very interesting. i will looking into that. thought of insulating my STi since its rather noisy stock as ya'll know. thanks for throwing that out there. i'll keep that in mind when i get back.
Front doors for now. Will probably add some in other areas. Trunk, rear doors, roof, floor would all be good candidates. Nah, I went for the premium stuff. Dynamat Xtreme. It's thin, not very heavy, and very easy to put on. Old school and cheap stuff generally involves heat guns, cursing and general hassle. Other than cutting the shit out of your hands this is a pretty easy install.
actually, the wheel welss are also a good place... lost of road noise from tires oh, and B quiet is also good mat www.bquiet.com
I think there was something called Brown Bread that kids at my old high school used to use. It was some spray insulation that worked really well and was pretty cheap.
i surrounded my speakers with it but it weighs so much if you do the whole car it gains you a lot of weight.
Alex over here at Moose's. He is using the dynamat xtreme, Ive held it, and it really is not all that heavy, just picked up aout 2sq ft sheet and it prob weighs at most 2lbs. The old dynamat is HEAVY, but that's oldschool, this is the new school So, in total, 3-5sq ft. per door x 4 doors + 4 sq ft for spare tire well = 16-24lbs additional weight for a car that is damn near silent on the highway. We just drove back up from the Master's, its by far quieter than my STi.
Nice. I'd like to see this done at an install day. Do the doors panels still look good after reassembly?
they are kinda all same but the company that makes them.. i used dynamatt in my old car, it worked fine, my friend just installed some cheap stuff and it worked fine and quiet
Please do not use Peel & Seal or similer roofing paper. Complete crap, and for a small amount more you can get a great product like RAAMmat. http://www.raamaudio.com/ Compare here http://www.sounddeadenershowdown.com/ I have raammat in my car and I am quite happy with the results.
I used 90% of one roll for just the chassis. If you are careful, you could knock out the whole car with one roll. I ordered two rolls, and plenty of Ensolite for mine.
sure its the same stuff ? does it have micro fibers that cause lung problems ? I know everytime i go in the attic to do something i itch for days. till the last time i wear a painters nylon jumpsuit but sweat like a pig in it
I am sure it is asphalt based roofing paper. Not really what you want in a car, unless you like the smell of fresh asphalt.
http://www.dynamat.com/technical_specs_dynamat_xtreme.html Weighs .45lbs/sq ft too. The bond strength is about 5x greater than original Dynamat stuff; trust me, it STICKS. (Alex can attest!) Wanted to add this too: Original dynamat has an acoustic loss of 0.08 at +68 degrees. Xtreme has an acoustic loss of 0.417 at the same temp. So the original converts 8% of vibrational energy to heat; Xtreme converts 42% ! The differences are less at colder temps, but Xtreme is still far ahead (.240 at 32F vs 0.16 at 32F).
No. Home Depot = asphalt based roofing paper (also known as B-Quiet Extreme, Brown Bread, Dynamat Original, eDead v1, eDead v1SE and FatMat) What you want is a butyl based product. Second Skin Damplifier, Damplifier Pro, Dynamat Xtreme, and RAAMmat. http://www.sounddeadenershowdown.com/
neat site. minor correction, B-quiet is actually a butyl composite. B-quiet Ultimate is just a higher percentage. and also moose, B-quiet ultimate is only .02 less on the Acoustic Loss at that temp, and costs alot less...I think I'll be sampling them against my last dynamat purchase and sharing with everyone. http://www.b-quiet.com/compare.html
I'll be interested in hearing your results. FWIW, their $ comparisons are a little off; notice how they base their price/sq ft on "150+" square feet ordered. Looks like 50 sq ft is $130 + shipping for around $140. I can find Dynamat Xtreme for $120 shipped for 36 sq ft. So $2.80 vs $3.33 for me... not a huge difference.
dynamat X is what i wanna go but can sum1 post a picture of how to install it in front doors.. cause the stock plastic and tar is there and the controls for auto door locks and how do i install it in there do i skip the doors and locks and just go taking out plastic and tar first.. i mean can sum1 explan how to do this so i can start on it?
