Soundproofing

[93Pgt]

I'm wondering if anyone has tried anything that works good in a hatch/trunk with a sub to reduce rattling and improve sound quality, ive heard of a few methods and id like to know what works good.
thanks

ive heard somethin about roofing material or somethin...otherwise you can go with the tried and true method: dynamat

roofing material.... no matter which product or combination you try it will stink something terrible forever inside a car

[PSiedTSi]

my buddy at work used it and hes got a pretty nice setup and it doesnt stink...he said its the exact same as dynamat...ill ask him on saturday exactly what he used...

[24valvenotak]

icedam or generic brand or any kind of foil type flashing uses tar... hard to believe it dont stink

[PSiedTSi]

its exactly like dynamat...

brownbread is good stuff, Vblock makes some nice stuff as well...no stench as it is not asphalt based. I can also get fairly easily the products on this page: http://www.theinstallbay.com/product_section.php?pn=22

Prices are anywhere from $6 to $100, depending on which kit you go with.

Not sure if it works but I have heard of people using the truck bed liner crap(cant member the name of it) or that foam that puffs up and gets hard(I know people have sprayed this in cracks and panels)

[24valvenotak]

the spray in bed liner doesnt stop much of the rattling at least thats what ive been told. Ive heard spot welding works rather nicely though..

on my old grand prix i used expanding foam on the trunk and other spots were there was metal close together. but you have to hatk your time and do it right esspecially where it is visable. the stuff is ugly

I have used the following:

Brownbread: works the best IMO but stinks, also melts in the summer.
Cascade VB2: thin, works about as good as the brownbread, doesn't stink
B-quiet liquid: visoelastic sound deadener, has to be painted on in several layers with a long dry time between each, but is great for inner trunk panels, inside doors, wierd surfaces, etc.
Dynamat Extreme: the old standby, works well. expensive though. you can get more for less. you are paying for the brand name
Hitemp Mastic: 'Roofing stuff' god no. stinks like cat piss. alot. always. forever.

thanks for all the info

I can get the cascade stuff as well I believe....

how much would a person need for an entire car?

http://www.raamaudio.com/ looking around I have found this site too.. seems to be different than tar-style. I think I might give this stuff a go.

i've used brownbread, all types of dynamat....they both work well..

i would never recommend using "great stuff" that foam that expands....

When I did my Convertible that I used to do IASCA with I put v-block in it but it had areas that were hard to put matting down so I had put the spray on also and it held up for 6 years and the only time you heard rattle was if i had the trunk lid open and the rattle was from the part of the latch that grabbed the stricker!!!!
