The not so easy Custom box

[KingManny 0]

Birch is looking a lot better than MDF atleast in Miami humidity for a 2002 Chevy Avalanche midgate enclosure. But I need help on the best specs to get the most out of 2 Nightshade 15's sub box. I'm going to coat it with spray on Truck bed liner to protect it. Sundown recommends a 2^3 enclosure but I just wanted any tips and the best layout that's worked for you all.

I have 2 SA-10's in 4cubes of box with 2.1 cubes of port, that would be sick for 2 15's as well. tune them to 28 HZ
