Sound deadening butyl is plain, but ice and water shield has gravel (like
asphalt shingles do) on top.
I have a bunch here from my home addition, but didn't try it due to this
fact.  It's heavy.

Subject: Sound deadening and door speakers

Hey folks - I'm in the process of replacing my damaged 2 front interior door
panels and got a couple questions.

First off, while I've got the panels off and door frame exposed, I'd like to
do some sound deadening. I've heard of people using "Ice and Water Shield"
which is a urethane/rubber underlayment used in home roofing. It can be
purchased at Home Depot, etc, and is considerably cheaper than products
marketed as 'sound deadening' specific, and it appears to be pretty similar
stuff. Have any of you used it for this purpose, or have any thoughts? And
would I apply a stick-on sound deadening material like this between the door
panel and the door, or is it possible/affective to insulate the inside of
the door (on the back side of the exterior surface).

The second part of my project involves new speakers. The replacement door
panels I got have no speaker holes at all (I think they came out of an '80
air cooled with no door speakers), so I've got the option to install
speakers in the lower part of the panel, where there is a larger cutout in
the door. I'm hoping I can fit 6.5" speakers down there. Has anyone here
been successful doing this?

Thanks!

Jon
