    You need 4 ports according to bassbox, they should be 4" pvc 16" long each. If your box is not deep enough to do this you can still do 4 ports and go 12" long each. Anywhere in that range will make that box pound. Don't go shorter than 12" long though, 16" would be ideal.

    I guess you could if you can't fit them all in the front, but they should be all on the same side as the subs. If you definitley don't have room to put them on the front then put them on the sides

    i know they're the kv.2s im just saying i built a box for two 13ov.2s designed by azn and it had two 4" ports. no port noise just pure bass in your face. also net cuft is the amount of volume after subs bracing and ports have been installed. gross cuft is the volume of just the empty box.

    its gross. u brought up a new point. what kind of bracing should i have in there? or should i just try it and see what happens to em cause i used 3/4 MDF and screws every 2-2.5 inches. And thanks for the help guys! I will finish it for sure tomorrow except carpet cause today i have a football game!

    well if thats gross then we'll need to tune according to net. since the walls of the box are pretty big then i would do one horizontal and vertical brace at least. whats the internal height and depth of your box? and how many watts rms will your subs be seeing?

    That's cool, the sides will be fine, there are a lot of boxes with ports on the side too, instead of the front. It's a big box it's needs that little extra. Looks well built, is that MDF? lol

    dude, you gots skillz lol. Looks solid i would just put one brace inbetween the ports from front to back. What are the outside measurements of your box, i thought 5.25 cu ft was the outside measurements.

    ok, if you can get me the exact measurements i'll double check it to see if there's much difference in the port lengths, will still be four, 4" ports
