Putting cotton in sub enclosure

[Drowsy 10+ year member]

OK, I made my enclosures for my 2 Polk Audio MM2124 12". The recommended enclosure size is .88cu ft. I know that is small and i think i missed it by a little, being that this is going into an el camino with almost no room. I have searched and putting cotton or polyfil in the box help makes the sub think that the box is bigger.

Question -

How much cotton do you put in for how much space you need?

Do you just lay it in the box, pack it, glue it to the inside of the walls, ect..

I think people generally say 1lb per cubic foot...

And use polyfil, not cotton.

Yeah Cotton makes airborne particles which can damage coils.

Poly for sho!
