If you keep those dimensions exactly with a little bracing and a double baffled top plate you would net a little over 7 cubes....you are prob going to want to run three 6" Aeros in order to have enough port area.......Three 6" Aeros 16" in length would give you about a 36hz tuning and 11" of port area per cube....If this is in an SUV of some sort I would do SUB UP & PORTS BACK............good luck

Double the baffle and you have 8.23ft^3 before sub and port displacements.

-.25ft^3 for sub
-.9ft^3 for three full length(17") 6" aeroports
-.1ft^3 for bracing

7ft^3 net...but with a 40hz tuning.

Sounds like you have room for a slot port, unless you're set on using aeros. 6 cubes net, 16^2 port area and tune around 35Hz since you mostly play rap...
