I just want a rough extimate before I go to home depot. mdf board, is that the same as partical board? Im a newb, i know =/. And I should seal with liquid nails and screws right? And my infity sub is reccomended at 1.25 cubic feet each. So Ill have to put them each in their own chamber correct? Any help would be aprreciated. The reason why Im building a box is cause I now need another sub. Im running 1 12 right now and it doesnt seem to be enough for my car.

about $50 US give or take.
$18 for a 4x8' sheet of .75" MDF 4" ID PVC tube for ports liquid nails caulk-tube 1.5" coarse-thread drywall screws (1 box)
you'll want a jigsaw, cordless drill/driver, circular saw if ya have one, tape measure, pencils a can of 3M super-77 spray adhesive automotive carpet and scissors speaker box terminals (radio shack) and perhaps a soldering pen and some resin core solder to solder the wiring to the terminals inside the box. lastly, some clear silicone (caulk tube again) and a caulking gun. this will seal the box inside around the joints, ports, terminals, etc.
