just wondering how this stuff actually works, and when it is used what is the best way to install it? in flat sheets or the stuffing?

It works by creating a longer path for air to move between the back of the loudspeaker cone and the inside walls of the enclosure, which simulates the same effect as a larger enclosure. The best method for using it is to pack it loosely inside the enclosure (not as flat sheets.) Keep it out of any port openings.

It just delays the soundwaves slightly, IE creating the illusionof a bigger enclosure... its a quick fast way to see if the enclosure needs to be larger... and the last poster is definitly correct, keep it away from the parts or you will have a confettti cannon on a big bass note :)
