Box for 2 Fi x10s

[Mikey1234]

I have 2 Fi x10s that I took out of my Silverado and I am going to put them in my Traverse. I was wondering what would be the loudest spl wise. I was thinking about a band pass box but I have no idea what the volume should be on both chambers. A ported box would be fine but can someone help me out on the specs such as volume and port size? Thanks

vas 22.1 L

fs 36.40 hz

qts 0.41

qms 5.16

qes 0.44
