Hey all,

I have some questions bout a stereo upgrade that's coming and figured here'd be a good place to start.

I'm looking to see if dynamat is worth the $$$ that people say it is?

or if there's a viable alternative that isn't as expensive such as Fatmat, stinger's buzzkill and or other products?

Looking at lining the doors and potentially all of the trunk to enhance the clarity of the stereo.

any and all advice to those whom have gone through this process before would be much appreciated.

Thanks!

There is an alternative/complement to Dynamat. It is called Quietcoat, which is liquid and you can apply it with a brush to any surface. You can buy it at www.quietsolution.com for about $70/gallon shipped, or you can buy it from S2ki sponsor, chipperman, for 15% discount.
I used it in the trunk and on the shell under the soft top with good result.

Or you can tune your sub to something other than the resonant frequency of your trunk. Depending on the type of music you like, bandpass may work well for this. The tradeoffs are more weight and less accurate bass(probably best suited to rap).

Cool thanks, I appreciate it!

So my guess is that you'd assume that I should use that for the trunk and the dynamat for the doors?

TIA..

If you have time to Dynamat the doors, it will be better. I did not do anything to the doors. If you do a search on Quietcoat, you can find some discussions about soundproofing. In general, the more time you can spend on doing the soundproofing, the more quiet the car will be. Someone removed both seats and carpets to apply Quietcoat on both passenger and driver floor, you can also apply Quietcoat to the rear wheel wells and under the car too. If you want to do all those area, you may need 2-3 gallons of Quietcoat. If this is the case, you may want to buy 5 gallon jug for about $200+ to save some $, and you can use some of it for other car(s)

I just recently finished up my soundproofing to get rid of the exhaust "drone" using a combo dynomat/quietcoat method. I ranked the areas of the car according to effect on drone, but as I look back on it, these are most of your noise producing areas.

WOW, fantastic information, thank you VERY much! great read and the link from a previous thread has def. made the decision much easier.

I think at this point Quiet coat for 1 gal makes complete sense and then dynamat the doors and then revisit the thought if I want more, etc...

hopefully in the next week it'll be all said and done.

laters.

I found a cheap alternative to dynamat. I think scosche makes it but wal-mart sells a door speaker kit for like $10 to start with. They don't have the complete car kit though.

Are you looking for just vibration control or sound absorbing as well? Dynamat has some decent sound absorbing material(s), as well as their infamous vibration control sheets.

There are other companies with better products for both vibration and sound absorbing as well, but they are more costly.

Procon and Cascade come to mind, but there are other manufacturers, mostly european who specialize in home audio/industrial, etc. sound dampening products, that can be used in vehicles, but they are hyper expensive.

For decent sound absorbing material, and the quantity you would need, be prepared to spend about $500+ unless you have a hook-up. for just vibration control...do the entire car for around $125-200

I use RAAMmat in the manufacture of S-Pods. www.streetsmarttechnologies.net
Made of the same stuff as Dmat for a lot less money. The seller is nice to work with too. http://www.raamaudio.com/

Good stuff. I have a bunch of that in the doors too.

saves a ton of $$$ over Dynamat and works the same, if not better :thumbup:

:iagree:


the RAAMat is good stuff. although it is thinner, when you compare straight up with Dynamat Xtreme. look at the pricing for total sq ft. with the Dynamat xtreme, you get 36sq ft or something like that. the price is over $200 bucks, i have seen them go for around $300, not sure about ebay prices on it.

with the RAAMat, for about $100 you get 64 sqft. now if you double layer the raamat, it is a lot more effective than 1 layer of dynamat.

i try to stay away from liquid deadners, since they are pretty new to the market, i feel they have quite a few flaws. there might be some out there where i do not have experience with, but with the E-dead from elemental, that shit smells, takes a long time to dry and after using liquid, you cannot add normal sticky back deadner to it. the adhesives on the sticky back do not stick well to the liquid deadners. i say this because it takes a good amount of liquid deadner to do the same job as 2 layers of RAAMAT.

Quiet Coat is my recommendation. You apply it like paint, and it does a superior job to "mats"

www.quietcar.net

I used this stuff to coat my centre console/transmission tunnel area (I have the clutch decel buzz), and it has almost eliminated most of the sound coming from the clutch on decel.

It'll also help of course if you apply it to the door panels, you'll pick up a fair bit of extra volume from the speakers.

Most people who had experrience with Quietcoat are very pleased with the result. It does not smell at all after it had been dried for a day or two. It does smell a little when it wets, but no more than normal paint. It does not take a long time to dry either, I had been able to apply 3 coats of Quietcoat within 2 hours in So. Cal. winter, using the fan to help it dry quicker. It is very solid after it dried, you can add RAAMAT or Dynamat over it without any problem. The one advantage of the Quietcoat is you can apply it under the passenger floorpan or rear wheel wells just like paint.

from what I hear a product called "dedskin" or something to that effect is a pretty good alternative to dynamat, I think a sheet to cover my trunk was somewhere around 60 or 70 bucks (it would have been enough for the trunk lid, and still have a bit left over to cut into small peices for the convertable tray)

Have any of you RAAMmat buyers ever ordered a half-roll or otherwise partial roll.

I just want to do my doors and a whole roll (fifty feet...!) seems like much more than I need.

How does dynamat work? According to their website:

Q: How does Dynamat stop road noise?
A: As a car operates, it generates noise. This noise is caused by the transference of energy (vibration) from the internal components and from the road to the chassis of the vehicle. The chassis (doors, floors, roof etc.) transforms this vibration into audible noise. Dynamat transforms the energy (vibration) into silent energy.

I'm not a physics guy, but "silent energy" is pretty hokey. Do they mean light? Light is silent and is a form of energy. No, of course they mean heat. The vibration and sound energy are converted into (miniscule) amounts of heat by forcing the energy to try to move sheet metal whose mass has just been supplemented by the addition of some damping material. Think about it, it now takes more energy to make that same piece of sheet metal vibrate or resonate, due to the additional mass of the dynamat. So the trick to effective damping is not in the name or the marketing, it's simply adding mass to the target sheet metal. There are other considerations, as mentioned in this thread, such as odor, cost, ease of application, etc., but the goal in damping noise, sound, vibration, etc. is to add mass.

This does the trick and is much much cheaper than Dynamat:

If you're not in a hurry I'll be placing an order within a week or two, and could spare some.

Otherwise, Rolling Audio in Sacramento usually has some on hand. 916-565-0100
