Started off with dual Alpine "S" 10s in a flat box, then TREO 12.44 in a BIG box, and now the TREO is back in a flat box using the spare tire area, then ported it.

Here is the box with dimensions. It winds up being 2.3ft3 after the .096ft3 speaker displacement.

Pics also of the gain of the sealed vs ported box using winISD and another gain chart.
