EVO IX sound system
If you're looking for lightweight sound deadening, Dynamat Extreme only weighs .45lbs/sq.ft. You can do your entire trunk and only add around 9lbs. Or, you can pay a heck of a lot more and use Dynamat Dynaplate (but the stuff is real good). It weighs only .15lbs/sq.ft. So, you could do your entire trunk and only add 3lbs. I think you would need probably close to 70 sq.ft. for the entire car (trunk, floors, doors, firewall). So, with Extreme that would be 31.5lbs. Or with Dynaplate only 11lbs.
If ya'll are still looking for a lightweight sound deadening kit, there's a company called FatMat. You can buy 100 sq.ft. for $100 (plus shipping). It's essentially the same as Dynamat Extreme from a quality and sound deadening standpoint (I read a "shootout" between a bunch of sound deadening materials and this stuffed tied with Dynamat Extreme). But, the best thing about Fat Mat is that the entire 100 sq.ft. (more than enough to cover you entire car) weighs 23 lbs total. That's it. Only 23 lbs to cover the entire car. Not too bad. My buddy has it in his RSX-S and it helped tremendously. I just ordered mine and will install soon. www.fatmat.com
