i just got mine back from being tubbed and i am going to use it. now that i have no a/c and my dash is pretty much gutted there is a good amount of road noise. i just ordered the 36ft. bundle off of ebay for 132.00 shipped. i want to cover every inch of the cab and doors that i can. i am also going to cover the hood that gets rid of alot of noise also. if its not enough ( i dont think it will be) i will cover what i can and get more.

 

You could put a layer under the headliner, under the carpet on the floor, doors, and hood. You could double layer it too.

 

Dynamat=$. Don't you wish there was a way around that?

 

i am doing double on my roof and tripple on the floor and over the wheel tubs...

the double on the roof of the blazer already made a difference...

Are you getting this stuff wholesale from somewhere? I never heard of double and triple layering it.

 

i have 3 layers on the roof, 1 layer on my doors, 1 layer in the speaker locations in dash and rear pillars. the rear wall and floor(probably 2 layers) is next on my list when i start my re-wire.

That's because you are a noob. Double and triple layering, while not as effective as alot of people think, is quite common.

There are many cheaper brands than Dynamat to chose from. A search for 'sound deadener' should turn up more than enough options.

Is it really worth the materials to double & triple? Just in some areas, or is there any particular application you might want to do it in? I debated it for a split second, but then I figured it'd cause fitment problems with my interior.

I picked up a 100sq ft bulk pack of FatMat for $99+ship, directly from their site. Fatmat.com, and it's worked out great. I think the only difference between fatmat and dynamat xtreme is the dynamat logo printed across the aluminum.

I used the same stuff, worked out awsome and is way cheaper then dynamat.

sure was effective on the roof of my truck. where 1 layer still had flex and rattled.....3 layes is stiff w/o rattles.

put it in places on doors, roof, or panels where you get the most flex.

Oh yeah I'm a noob because I only have one layer of dynamat extreme on my truck. I just never could imagine spending the money to double and triple layer my truck. Hell just single layering cost a pretty penny.

Actually you're a noob because you've never even heard of anyone double layering. Again, its quite common.

If you are considering double or triple layering, you have to ask yourself what your goal is. Is it for less road noise? If so, there are better materials to use such as closed cell foams. If its for added mass loading (stiffening the panel more), you should consider going with a single layer of a better quality or thicker material. Layering the mat stuff does add more and more mass, but mass loaders like that work better the better that adhere to the panel. Once you start getting multiple layers, you start having sagging problems with some cheaper brands, air bubbles become a real hassle, etc etc. Again, if you can acheive the same (or close) results using a single layer of a better material, you'll be better off.

That being said, as someone else above said, sometimes adding multiple layers in certain strategic areas can help. Im certainly not saying multiple layers do nothing, only discussing possible better options. For example, the roof of my blazer flexes very badly since I shaved the luggage rack. I could tack two or three layer of mat up there and hope it stays. But I dont necessarily need to add weight, just stiffen the roof. So I'll be putting up a layer of fibergrass (cloth soaked in resin), this should effectively stiffen the sheet metal. I'll then spray a layer of sound deadener over the top for a sound barrier, and be done. It will weigh considerably less than multiple layers of mat, will stay up forever, cost less, and be just as effective.

Just consider your goals (two main ones in sound deadening: mass loading/stiffening, and a noise barrier/absorber). There are many ways to skin a cat, and just adding more and more layers of sound deadening mat isn't always the best plan.

I'm not a noob just been out of stereos for 4 or 5 years. Just not aware what is going on in the audio world right now and don't care to either. A noob is someone that runs around with a stereo in his or her car and doesn't know they could put dynamat in the car to help sound deaden it and prevent vibrations. It almost makes me sick every time I hear one of those buzzing trunks go by.

 

i think i could use about 500 bucks worth of dynamat to keep my bed from rattling

 

damn 500 bucks... :haha: anyways i'm just dont want a lot of road noise coming through. Also will it bring out my mids more since they are low if i dynamat or fatmat the floor and firewall?

Okay. I'm not out to compete in SPL, just wanted to stiffen up the cab a bit and ditch a little road noise, so it sounds like I did the right thing with just a single layer.

Thanks for the info man.

Try not to flame others folks, I don't want to have to tear up a thread with good information in it because of a few snide comments.

Sheit dude you could probably get a new bed for cheaper if that's the case! :haha:

 

do, di di do, dum didi dum.... for about the same price as to dynamat, brown bread, dead beat, whatever your interior!
Especially after a body drop and tubbed fire wall,, you can get your interior Line X. or Rhino lining for about the same cost!
Spray ons give you better coverage, even coverage, block out sound as good or better than the stick on stuff,, it water proofs everything and actually strengthens your cab!

Where I used to work, Van & Truck World, one of the stores did this to a customers car,, they said it was amazing how much road noise stayed out, and how much audio improved!

Yep. My buddy does Vortex lining for a living and spraying the interiors of boats and autos is one of the applications he offers. I didn't want to go THAT far, since I'm not body dropped and never really had a problem with road noise in the first place...

along those same lines, eDead and Second Skin now have products that you actually brush on and it's supposed to be pretty good. never tried it myself, although i have been tempted.

 

Id prefer to use the bed liners on the outside of the vehicle, it works great there and is a good rust preventative, but use an actual spray-on deadener for the interior. But either way works well.
