Was going to do some fiberglass pods for these but just found out how much I hate fiberglass, LOL.

Was wondering if someone had some time, and wanted to of course, maybe design a nice small ported box for these. Would prefer a square port, so I can build it this weekend (no ordering aero's or anything).

Four MA Audio 8" MA80XE subs (1 common chamber, shared port or 2 chamber, 2 shared ports are fine)

Sub Specs
Fo (Hz) 38.31
QMS 4.23
QES .34
QTS .31
VAS (liters) 21.33


Recommended ported enclosure (per sub)

Cubic Feet 1.0
Hz 43
3db down point 40
Sq port (sq./in.) 7
Port Length 9

Going in the back of a S10 Blazer, but the smaller the better.

Any designs are appreciated. Thanks
