Needing help with a box design

[Alex859]

Hey guys I'm about to do a build in my 08 silverado extended cab I ordered 2 AB xfl 15s and a Ab 120.1 amp. I measured the max space I can work with and I got,

Length 54 width 22 height 34

I would like to have a ported box tuned low maybe 28-29htz, I will be running 0 Guage throughout the truck and big 3 upgrade! I hope you guys can help me with a box thanks ?
