Pretty easy to make a sub box. See if you can find the speaker displacement in cubic inches....If not see if you can find out what volume is needed for each speaker.
I use this site alot: http://www.radiomods.co.nz/speakerboxcalc.html when I'm making speaker boxes, until you run into odd shapes, then its geometry and math time!
