Dynamat is about 1/8" thick, and comes in sheets. I used the
type that has adhesive on one side. It must have lead in it,
because it's very dense, and actually works like a sheet of lead
would, only more flexible. It deadens sound because of it's sheer
density. As you know, it takes energy to vibrate something, and
this stuff being much more massive that sheet metal, it will
quickly dampen any sheet metal from vibrating which would
otherwise create some unwanted sound.
I've never used it before, but a lot of the people I spoke to
swear by this stuff. I was already spending about $1000, so I
figured another $20 or $30 was no big deal. I haven't done any
before/after testing, but I can tell you that the system sounds
great now. The difference is probably small, but who knows.
I installed a 8X12 piece (roughly) on each door frame around the
woofer. I removed the plastic adapter that holds the speaker to
the door frame, and put the dynamat on the door frame. Then out
the adapter back on. I attached the cutout piece from the hole in
the middle against the inside of the door skin, opposite the 5
1/4" speaker. I'm pretty sure I included that in the
description.
I added a third piece to the underside of the rear deck. I
basically put it everywhere that didn't have a cutout or
something in the way.
