Using great stuff around an enclosure

[jonhfl]

Hi all, I am a newbie to the forum and a fairly novice car audio installer.

I am in the process of building a dual 10 in sealed enclosure in my spare tire well. I have mocked up a box that has the proper air space for my subs however around the box there is alot of space and is a very awkward shape.

I was thinking I could set the box in and then use Great Stuff foam and fill the void around and under the box. However I noticed Great Stuff says it is a sound barrier.

Will putting this around the box reduce the bass or is the bass really just coming out of the top of the subs?

If that won't work and other ideas of securing the box aside from just cutting some mdf pieces to basically brace it at different points in the well?

Thanks for helping.

Don't use the uber crazy expanding stuff. That's a mess

Are you saying don't use it because it is messy or because it would dampen the bass too much. I was going to wrap the area with a plastic barrier and also the box so the foam wasn't actually expanding onto the car.

What else could be used to fill the voids and secure the box since the area iseems such an odd shape compared to the rectangular box?

Thanks

It's messy.

Out of all the expanding foam I have used. The Hilti seems to be the best one.
