im going to run (2)JL 8W3V3-4 the cut out holes are not to scale but i would like to port this box. JL recomends 0.35 cu. ft. ports 2 in x 18 in. tune to 35.0http://mobile.jlaudio.com/products_subs_enclusure.php?series_id=27

Gonna need depth #1 on the lower wing for starters, as it is angled back and has a different depth on top than the bottom. Then you have a seperation shown between the 2 boxes, are they seperate or can air move freely between them. Also If you know what dimensions you need, then I would suggest going to http://www.bcae1.com/spboxnew2.htm and punch in your measurments using the many calculators avaailable. Break the enclosre up into seperate shapes then combine. GL
