4th Order wall in a ZX3

Im trying to figure out how i can build a 4th order wall in my zx3, i was talking to my team captain, and he said go with 8 cubes sealed 48 cubes ported, and work my way down layering the inside till i get it just right. im going for a low tuning freq but i want it to play 30hz-50 hz i just have no clue how to get that out of my car. note this is for 2 RD audio Alpha 15's on a sundown saz 3000d @ .5 ohms. any ideas to get started on this project?

First off, No way in hell are you going to get that many cubes ... throw them in 6 cubes sealed and 9 cubes ported for a 1:1.5 ratio ... it will be very musical and play well . Use double layered 3/4" birch with double layered baffles for the subs . use 1/2" all thread to secure and brace your box .
