Dynamat??

[Robbo VS3]

Wow, the amplifier i put in my ute has made all the difference to my sound system. It is now louder and more clear. But one downside is that my whole cab now vibrates like a bastard, its actually really bad, the vibration nearly overpowers the music. The vibration is only bad with songs that have lots of bass, most songs are alright, but i do listen to some bass heavy music.
Since it is only a ute i will only need 2 pieces of dynamat. Does dynamatting really work, is it worth buying it? Will it stop all that vibration?

Found this on ebay, seems pretty cheap, what do you think?

freom what i have heard it works well, but thats just my opinion.

[StoneX]

Dynamat isn't for vibrations, it's for deadening metal panels. Metal panels resonate (hum) in time with certain frequencies so adding Dynamat to them makes them heavier and dampened so that they no longer resonate at those frequencies.

If you have rattles, you need to find the rattles and separate the two items that are rattling against each other. Foam and rubber are good for putting between rattling objects.

[Tasmaniak]

and expanding foam can more often then not lead to distrastrous but funny results.

[acarmody]

Yeah I remember the local installer telling me about a guy that blew his boot lid apart putting too much expanding foam in between the two layers. That shit expands a LOT with a LOT of force, really trippy for foam.

Also that dynamat on ebay your looking at is only two pieces of 25cm sqaured. If you want to do a really good job you will need a lot more then that.

Funny as eh!
Dynamat should work ok plenty swear by it
but still can't stop the side mirrors wiggling like crazy though
I used Lino works just as good I reakon.

[Robbo VS3]

Ahhh, thanks Rob, that reminds me. Does anyone use any home made stuff to stop the vibration. The lino you mentioned Rob sounds good, and i think i have some of that lying around home too. It will save me $40 anyway

[StoneX]

You'll need to buy some good glue to stick lino to your panels... Plus it's not very effective compared to actual deadener.

I used carpet underlay and whatever foam I could find to jam in between vibrating panels and door trims and lots of deadener on all the flat metal throughout the car. Still have to do my roof one day though.

How well does that underlay work when jammed between the two boot panels? Plenty of vibrations there, spoiler goes crazy.

[StoneX]

Which panels?

If you're talking about the boot lid skin and the bracing, I'd put rubber in any gaps that are moving and then deaden over all the flat sheet metal.

What I did...

[VZ-Rob]

StoneX that's a pretty neat install

another alternative is Flashtec Tape from M10 or Bungs
gona try it on the back panel behind the seats

[acarmody]

Yeah that what I meant, rubber? What sort of rubber?

[StoneX]

If it's inside the car you can jam anything in between rattling items. It doesn't need to be anything special as long as it stays in place.

I used Flashtac on my first car and it was OK but I used 3 layers of it and ended up painting K&H Brush On Deadener to make my doors completely dead

In my cars since I've used proper sheet deadener(G-Spot Serenity MAX, RAAMmat 60 BXT, and Dynamat Extreme) and it's so much easier to apply and 1-2 layers does as good a job as Flashtac and paint on deadener combined.

In the above car I used about 100sq foot of RAAMmat deadener, nearly 3 Dynamat bulk packs.

[acarmody]

RAAMmat, isn't that the stuff on Ebay. Any good?

[dynoryder]

hay all f u c k that dynamat s h i t my old man is a waterproofer im gonna use some of his powerderd membrain s h i t its called gripset it is perfect plus there are a few other membrains

you just mix it up and paint it on

for the record i have a eclipse 4000w titanium pro 15 sub i payed $1200 worth $2000 it was last one in canberra now they stoped makeing them

[StoneX]

I bought my RAAMmat directly from the manufacturer in the US. Yeah, it is good. Pretty much the same as Dynamat but without the logo. It cost me $370 for 108sq feet... Which is equal to 3 Dynamat bulk packs which are $225 each.

dynoryder... Dynamat is made to do a specific job. It does that job well. Other products designed for waterproofing, etc are not designed to deaden panels and absorb resonances. So it may be cheap but it does do the same thing as Dynamat or other proper deadeners.

[dynoryder]

mate the stuff in dynamat is like this rubber s h i t from usa it's latex bitchamin i have used it with my old man it is the same

the powderd membrain is stiffer but cheaper it has latex to

How old are you?

Must have been expensive to freight, that stuff weighs a lot.

[dynoryder]

i dont usally talk back to comment like that but i am 21 i have worked at a car audio shop have worked for my old man and i know am a mechanic

[dynoryder]

dynamat is also the same as the little patches of black shit coved with foil in the old xf facons it is used to cover the top of the rear shocks under the seats have a look if you can find a xf

that black stuff also happens to be just like modifyed bitchumin latex membrain

[D-Man]

you'd think at 21 he'd be able to spell...

still hope out there ?

and dyno. you dont sound very convincing... you sound like you know nothing at all but try to make it look like you know everything (please note - im not saying you know nothing. just how it's soudning to me)

and since StoneX did such a great job with his, im more likely to listen to his recomendations than yours.

no need to swear dude. it just lets us know that your a true tool.

[dynoryder]

i do sound like a tool it's just ive spent a lot of time thinking of cheaper stuff and the best i could find is membrain

i mean ive been thinking of this for like 2 years havent done it yet but preperation is the way im going

my sub box in my room has polyurathane sealent in it in the corners and that acrlic wool stuff got all that stuff for free off a building site when i was working for my old man it has made a big differnce

so that study has helped me come up with the membrain idea

[Philthy]

Well throw it in and let us know how it goes. However, since I'm going to assume you haven't used dynamat before, it will be hard for you to make a fair comparison
