i can give u 10 inches but the subs only need 1.05 cubic inches
no, they need 1.75 cubes in a ported box. i just looked it up.
the internal airspace will be about 6.5 cubes, port and subs will take up somewhere around 1 cube. leaving you with 1.37 per sub. thats with no bracing or 45*s.
ok well i know that i cant go any wider then 3 feet and any higher then 11 inches i just took another measurement and i think i can make it 40 inches long it will be a tight fit but thats all i can give u
