The general guideline when it comes to Polyfil is you want .5 - 1.0 lbs per cubic foot. Some experimentation is probably going to be needed.

I'm gonna start with .5 thanks a lot for some help don't really understand y its works I know it absorbs the sound pressure and tricks the subs but that's about it don't know when it's needed or y it's needed. Shit my box is .6 after displacement so I will split 1 bag for all 3 chambers right.

nice simple read about how it works and its in basic terms.. its really easy to understand ..

While that post gets it mostly right, there is some stuff that's wrong there too. Stuffing a box lowers it QTC which flattens out the frequency response and lowers the F3 point, similar to what happens when you make the box bigger. However stuffing a box does not increase efficiency or increase cone excursion like making a box bigger does. Stuffing a box will cost you a little mid bass output, but gain you some on the low end.

Here is an article by Josh Ricci about stuffing: http://www.data-bass.com/data?page=content&id=79
