<![CDATA[Soundproofing]]>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

i went this route due to money savings over others.
it did stink for a bit though since it is asphalt based.
the expanding foam was used in the trunk lid and helped alot. but be careful as i sprayed that when it was still a little cool. and as the temps rose it expanded more. no bulges or anything, but i did have trouble a couple times opening my trunk since it had come out the holes and started to cure where the lid met the seal or the metal.

but there are lots of options out there now.
hit some car audio forums and see what is used and what works.

remember though that this adds weight. so if you plan on racing know you will be slower if you add alot. if done higher, as in upper half of car it will also throw off things a little bit.

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

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.

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.

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.
