Just for sh**s and giggles

[CrossfireExpedition]

Just for sh**s and giggles i was thinking about putting 8-10in Crossfire BMF-1028 subs in my Expedition for USAC comps. I am looking for some input here on how to go about it with design. Does not have to be a daily box. Was looking at running about .75-.85 per sub ported. Truck itself peaks right around 40hz. I came up with a enclosure about 5.90 cuft with 4-4" round ports @ 10.09" long(thats right around 42hz). What are your guys thoughts on something like this ? just looking for some input. By the way the vehicle is a daily driven 04 Ford Expedition so I need the box to come out when not doing competitions. This set-up will be ran off 1 Crossfire BMF-1700d. Thank you all for your input.
