Full Version: sound deadening - seriously

I'm investing some decent equipment in my new install and I wanna know what people think about sound deadening

Project #1 will be to sound deaden the **** out of the doors, now, I don't mind spending the $$ to get good results but at the same time, I don't wanna have to spend more than I have to. I don't necessarily believe that you have to buy brand names to get results but I do believe you get what you pay for.

With that said, the legendary guy who will be helping me with the finer points of the install works for Bourbon!


Anyways, back on topic - what I want to know is, is stuff like flashtac any good? Who has had experience with what deadener and what are the results?

I wanna hear from everyone who has used any form of sound deadener and I wanna know what you think. Especially installers who have been subject to the financial limitations of customers and so probably would have used everything under the sun.

Let me know ladies and gents

I have used Flashtak, Stinger Roadkill and the Jaycar stuff. Out of these three Stinger buy far sticks the best followed buy Jaycar and last Flashtak. The Roadkill stuff I used cost around $85 and was not enough to cover one door. Jaycar is $22 per 60cm x 60cm ( It comes as 2 sheets - 30cm x 30cm)The Flashtak was cheapest @ $26 for 10m x10cm. I rekon the Flashtak is prolly the same stuff as the Jaycar. I ended up buying alot of Flashtak and sound deadener paint from Supercheap (to act as a glue) 2 layers of Fashtak with the "glue" Is heaps and goes a long way. 2 layers would easily rivil the Roadkill.
In my opion anyway.

flashtac is great, cheap and does a good job if you use two layers. it sticks fine in my experience, clean the surface first, and press the sheet down firmly getting out all air bubbles, to ensure it is properly stuck on (i use the back of a screwdriver to roll over it and push it down).

a little secret about sound deadening - most of the rattles you hear are not the panels themselves - they are the little parts attached to them, like lock rods, switches, clips, cables, glass, reflector housings, winder assemblies etc etc. thsoe things must still be able to move, yet you dont want them to rattle - therein lies your challenge (hint: test tone cd, foam strips and lots of blue tac )
Mr_Bob
serenity max is the best value for money IMO, it sticks eraly well, and is equivalent to dynamat exrteme, for much much less...
i've used over 15 square metres of the stuff in my car, maybe as much as 20 square metres, i've lost count.

whatever you do, preparation (cleaning, etc.) is the key to good sound deadening,
if the product that you chose is inferior, you can always just use more, but if the surfaces aren't prepared correctly, it won't matter what you use.

yeah, G-spot serenity max is the best value stuff i've used (serenity max, dynamat xtreme, brownbread, flashtac).

dynamat xtreme is easier to apply and probably a bit better, but more expensive.

aside from SDing, ensure you seal off the big service holes too, and mount the speakers very securely without leaks around the edges. i used 3mm mdf to seal the doors (painted in undercoat to protect against moisture) covered in a layer of SDer. also used self-adhesive 'closed-cell' foam rubber stripping (eg: from clark rubber) to act as a seal/gasket between the mdf and door and around the speaker/pods.



G-spot paint is useful for crevices and to cover the door lock rods, etc.

good luck

Is having a foam thing acting as a gasket necessary? Does it make a difference in helping the door panels from rattling and vibrating?
rheetard
dynamat extreme is the best **** so easy to apply!
That said, I sound deadened my boot and the ****er dont rattle no more good effort for a commodore i rekon

nah, it's not to stop rattles, but to ensure the door is nicely sealed. it's difficult to get mdf panels to fit snuggly against the metal frame without some gaps, so the foam rubber blocks those gaps.

this is the gf's car, used heaps of flashtack and g-spot paint, the paint is awsome stuff!!!

awesome dude, I'll check out your doors tonight for sure! I'm pretty made up to use g spot or similar on the outer skins of the doors and definitely using flashtac for the boot and hatch, but for the doors, I reckon it might be worth spending a bit more... given that I'm spending a crapeload on the front stage equipment, I don;t wanna skimp

i would agree with the general consensus that serenity soud dead is great stuff. it's the only stuff i've ever used, but i managed to do both metal panels on each of my front doors, first go, without many probs at all.
the hardest part is just measuring to size. but what i discovered was that it's better to have a piece thats too big, than too small.
the bigger the pieces u use, the much less time it takes. and it looks better too! lol
nemesis
i'll be in the ricer pulsar tonight, so check out the rear quarters, bootlid, and doors, ive spent around $500 on sound deadening for it and tapping a panel sounds...ahhrr...dead..... lol
smeg
good stuff Adam

looking forward to dulling down the exhaust noise a bit too
roughcactus

Bookers?! haha, why do I get the feeling that you'll drink 4 weeks worth of wages the first day and then the next day you'll call in "sick"?!

rheetard

smeg

rheetard

I have used the G spot ser max , its really easy to stick on!! when i first looked at my doors i nearly had a coronry, but as soon as i satrted and real realised how eays it was to apply, everything was better!!

So easy to apply, sticks on with ease!!

Not too badly priced, depends on if ya want the serenity or the max!! max is twice as dear!

you can get it from CAA sponsor audioart & technology , which is where i got my 'door kit' from, efficiently posted interstate too. ~$200 delivered would be a very reasonable price.

but i do think the dynamat xtreme is better, if only coz it's easy to apply and much stickier, but presumably it has better SD properties although i cannot confirm that. the door kit was more than enough to cover the entire outer skin of both my front doors. i then used serenity max and paint inside the door cavity.

i still suggest serenity max as being better value though, and definitely not obviously lesser in performance.

rheetard, have you personally compared G-Spot products to Dynamat, coz you seem very intent on swaying Aaron away from G-Spot and over to Dynamat.

G-Spot Serenity Max, is more effective than Dynamat (only difference being not as workable as Dynamat Extreme) but it is better value.

Aaron, I have some samples for you to look at if you would like to play around with some.

wtf?!
1. I am not trying to sway him away from g-spot at all. Where did I even mention g-spot?
2. No I havent used G-spot serenity max. Ive seen the painton stuff, although I got nothing to compare it too
3. I am recommending dynamat because it worked FOR ME. is there something wrong with this?
4. I love dynamat extreme cause im a lazy ****


EDIT: Isnt g-spot bringing out some new serenity mat with foam and stuff?

Shiny Car, where did u get the foam stuff to fill the gaps????
shiny_car
places like clark rubber sell self-adhesive 'closed-cell' foam rubber by the metre off a roll. you can get it in a couple different widths too, say 1/4" or 1/2".

jaycar also offer it as an accessory for speakers, but is not surprisingly more expensive per metre (i think they have packets of 3m or something).

smeg
thanks for all the info and feedback guys

Marc - I'd love to take you up on your offer, we gotta catch up soon
