Cheapest Sound Damping Material

[saj3n]

I've decided that this week I'll go ahead and install my subs, I want to "dynamat" the trunk to prevent as many rattles and such as possible. Anyone have connections or know of the best place to pick some up? I'm looking on ebay now...

If you know any friends that work at Bestbuy, I'm told its cheap as hell there. From my own experience, car audio equipment is dirt cheap from Bestbuy (I got a ~50% discount on my whole system).

BTW, my trunk rattles like hell, but I found the only thing I wanted dynamatted was the cardboard fabric piece between the rear seats and the rear windshield. Be sure to dynamat that thing like hell, as my one layer is sometimes not sufficient. And stick it on there good, in cold weather it tends to lose effectiveness, I'm thinking because of less adhesive properties in the cold. Good luck.

BTW... what are you running?

Thanks, I'll have to see who I can find that works there... I'm sure I have a few friends.

I am running 2 Alpine SWR-1242D's (1500watt max - 500 rms) pushed by a Hifonics Brutus BXI1206D 1200x1 @ 1ohm watt monoblock class D amp.

I am scared of how loud it will be! I ran 2 pioneer's back in the day, maybe getting 150-200 watts each, and my 89 525i rattled horribly! Although, it was mostly the trunk lid which rattled. So I can only imagine what this will do...

Holy crap dude, I'm only running one Type R, and it bumps pretty damn good. Two should be some good fun for ya... but I'm a bit concerned about rattling. And despite the amount of material separating the trunk from the cabin, the type r's sound really clean. Hope you have some capacitors though, cuz my lights flicker already.

BTW... did you know you could have purchased the Alpine SWR-1242D's from Bestbuy for ~$85 a piece? Supposedly, Bestbuy and Alpine are associatted somehow, and employees get even more discount on all Alpine equipment in general.

Anyhow, enough of me talking about how cool it is to have a friend work at Bestbuy, good luck with the system install.

Sajen, Where do you live? I work on Concord, Ca and see a e34 around that looks just like your's around. If you live around I can hook you up with a good price on Dynamat.

[saj3n]

I'm in Philadelphia, PA.... Anyway that good price would still be available over here?

[saj3n]

$85!!! Not bad! I figured I got mine for a steal, $200 for the pair, but wouldn't have minded saving that extra $30. Yea, I'm thinking that I'll most likely need a Cap for the system or a High Output altenator (heard much more effective than capacitors). The battery is new, so that shouldn't be a problem. But we'll see just how much it rattles when I get them in there. My amp should be here by Wednesday. I figured that I'll install everything by Thursday, and then do the dynamat and put a cap in, if needed, later that week or early next. I'm sure i'll be spending a few hours tuning the system perfectly. It's been so long since I've waited to finish this system off. I started a year and a half ago, and only have cabin speakers & deck installed (they sound AMAZING mind you) but now my SUBS!!! YAY!!! :-D

So, about this friend at Best Buy... :-P

You'd be amazed what spray-on bedliner can do

I dunno if I'll use it in certain places on the bimmer, but in my Wagoneer, I used it almost everywhere and I could barely hear my 413 big block!

I can tell you what it will do.
Go pick up your phone, hear the dial tone?
Wanna hear it for the rest of your life? I have for the last twenty years and am ****in' well sick of it!
It's your hearing bud.
