[QUOTE="WhiteYota, post: 8384876, member: 664829"] Hi all, I am working the the box design for my 2 18" xcons and am running into space issues, not cubic footage but space to mount subs and have ports. It has to be a tall box with either ports and or subs up. Size I have to work with is 22 x 40 x 40 tall (about 20 cubes gross). The issue I am having is the diameter of the sub flange is 18.5 - does not leave much for port on the long side and adding 2 subs would be 37 - so not much to put ports on the short sides either. Was looking into either a 4th or 6th but I can not find anywhere that gives a formula to get a cu foot size that would work. Most of the posts I found on the net say the size of a small house but that is in no way realistic numbers (small house 100-200 cu ft, ya right). Was also looking into running isobaric where from what I read it takes about half the size of box, but then still running into issues of determining size of the box in the first place. I have no issues with modifying/rebuilding a box however many times it takes to get right. I could run just 1 but that would be no fun lol I looked at Jeff's box but I think when Toyota redesigned the van in 2011 they changed the space in the back. At least from what I found on other Sienna web sites where someone was asking about cargo space dimensions. [/QUOTE]
