Ok, this is going to be a quick how to, using sketchup. This not a tuned box, it is just for demonstration sake.
Start off by measuring out your bottom piece of the box, and drawing it out.
Now that you have the bottom of the box measured and drawn, use the push/pull tool to pull it to the desired wood thickness. (Usually 3/4")
Now take your measuring tape, and click on the edge of each side and pull in 3/4" (or wood thickness)
Now draw lines with the guides still there, and then erase the guides
On this example I used a 3" wide vent, so take the tape measure again and measure 3" in from the inside of the walls, on the side and back. Then from those lines measure out another 3/4" with the measuring tape.
Then erase the piece in the front of the port and the guides.
