mcuh better much better! now i have the money for that! its all the same right? like is there any difference in brands? idk if the box is just different or what cause it all looks the same to me. dynomat is a new thing to me i know u will need it on the roof and the doors and the back.. will i need it under the seats in the floor board? do u think ill need 2 of the boxes. 72 cube feet of it? or just one box?
I used bithane in my car instead of Dynamat. It's about 1/8" thick, self adhesive, flexable, foil backed and cheap. I got mine from a window installer for free since it is used to waterproof around house windows. I covered the entire floor and firewall and added some high density foil backed rubber foam on top of the bithane.
i am going to double it up in some places. prolly the back hatch door thing that the ports wil face and the roof. should i double up the fire wall too? i am really not looking forward to take thing dash off. yuck. its going to take forever
My dash was already out as well as all of my interior. I started out with a bare shell and am building a custom Javelin with the dash out of a 2004 Dodge Ram. All areas that needed the sound deadner were exposed and covered before any interiour was even started. I even did the roof. The stereo is still in the boxes (all Alpine)so I haven't tested it yet other then pounding on the panels from the outside and noticing how thick they feel and how the absorb sound. The stuff sticks great and doesn't come off without lots of work. I havn't done the trunk yet, but the 2 12" subs will actually be inside the car where the original package tray behind the rear seat was.
