[QUOTE="Freelander, post: 4902697, member: 576814"] My box was supposed to be 22Wx22Dx18H but after it was all said and done I got 18.25Hx20.5Wx22D. From my calculations that's going to be 3.776ft^3 before port and sub displacement. I'm running a 15" FiQ. Which has 0.19ft^3 displacement. I'm wanting the box to be tuned to around 32hz. I do not think I'll be able to put the ports on the same panel as the sub because it would be really close to the walls. I bought two of [URL="http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=268-352"][B]THESE[/B][/URL]4" Precision flared port kits. What would I have to cut the main tube down to to get the 32hz tune? The main tube is 12" long, with the flare on top and bottom its a total of 18" long but I think the flared part of the port only counts as half of its length which would make it 17". Also this is going in a small SUV. Should I run sub up/ports back or should I run sub back/ports up [/QUOTE]
