Me and a buddy are building a box for 3 12 inch w6's, I was curious if I could have them all in the same chamber or if I should divide them all into individual boxes we already have the entire box built excluding the face of the box.. The dimensions are 51 3/4 wide by 16 1/8 tall by the top board is 15 inches deep and the bottom board is 18 7/8 deep (the box will have a slant face)(I am also using 3/4 inch mdf). I would also like to know how big I should build the port I wanna get about 32-33 hertz. Any help would be very much appreciated.

You can put them all in the same chamber. As for port area, 60-70 sq. inches should suffice I'd think. Your box is just a little under 6.5 cubes gross I think, so you don't want to take up too much room with the port. More port area will require a longer port and thus eat up more room. You could probably even get away with three or four 4" aeroports.
