down firing,rear firing, up firing,front firing sub boxes
 

I am inquirying about sub box that are design to be down fired. I plan to have 2 - 8" subs located behind the aluminium bar where the foam piece is located in the rear hatch area.

I am wondering how well this would sound compared to some of the other typical sub boxes designed and locations (i.e. Zenclosure rear firing box, frotn firing sub box located in the rear quarter panel -see chops thread).
