I am building a split sealed box for a pair of 10 inch Cerwin-Vega HED's. The drivers will be firing upward. The boxes will be placed over the wheel wells on each side of my Explorer. Since the box will be over the wheel wells, there will be two different depths. Will this effect the internal box air pressure? Will there be any performance loss because of the 2 different depths? I plan on filling the bottom half of the box with polyfill. Thank you in advance to all those who can help.
