I have seen alot of boxes with 1 or 2 subs fireing into the box I just want to know it there is a reson for thator is it just for looks. If it dose do something say I have 4 subs and want 2 to fire in would it be 4 sealed chambers or 2 or all in 1 chamber? I just really want to know what it is all about.

A loudspeaker can produce sound from both sides. In or out of phase.
When you see a box, with the speakers inverted, it could be 1 of two designs.
1. The speaker is being run out of phase and is essentially being used in reverse. They are not firing into the box, or else you wouldnt hear anything (or hardly anything).
2. The speaker is being run out of phase, and, isobarically loaded (probably compound, i.e. face-to-face), inside the box there is another speaker run in phase. By using 2 subs in an isobaric chamber, you cut your Vas in half, which means you cut your needed box size in half - for one speaker.
