Sound Deadening

[Hunter844 0]

I am building a small sub box for my 2001 S10 ext cab ZR2 using a shallow mount MB Quart driver. I'll be mounting on the rear wall of the cab. Anyway I pulled off that rear wall panel and discovered there is a cavity where I should be able to do some good in terms of sound deadening and wondered if using regular spray foam found at home depot will actually do some good? Is it dense enough to stop sound or should I be thinking about another solution? Mind you I'm just looking to have it better than it was to cut down on road noise since I've got that area opened up...not looking to spend a lot of money or have to order more products in.

Picture of area? Are you talking about space between two metal panels?

Yes it will, just make sure air can get to it so it can dry or it can take months before it dries if ever.

Yes, it's about a 1.5'' gap in the biggest portion of it....I think I can get an area about 16'' x 54''. My plan was to get a longer hose attached to a can of foam and get down as low as I can go and just start working my way up.

Far from done but this is the gist of what I'm going to do.

@Skullz

Drying out shouldn't be a problem.
