Thanks, I should have at least .75. DO you find a bigger box is better for a sealed box? I had a sealed box that was 2.23 for 2 JL audio 10's (just older regular ones) in my HUmmer H1 and they sounded pretty good. Now I'm wondering if I should make a smaller box for the H3 I have.

I prefer a large sealed box over a small sealed box. It helps provide a deep low sound. Smaller boxes will yield a slightly quicker response.

The old box was 46x12x7 ( around 2.23 cft)

The new one I want to make today is around 41x19x5 ( around 2.25 cft)
