Now, Help me make it loud.

The Subs: Mach5 MJ-18 8 ohm version

I was thinking 10 cu. ft at 35 hz, based on WinISD, that would give me 4 4" PVC, cut 8 inches long a piece

However, I'm sure there are more experts here than me, what do you guys think would be optimum for pure SPL outta these babies?

Just Got SketchUp, decided to design the box for the two MJ-18s from Mach5

This is a final production image, with the top and front being red tinted plexiglass, the sides being 1" MDF, painted maroon

Ports are 4" x 8" firing toward the cabin, hopefully clear PVC at the end.
