A:AnswerThat american bass elite needs a box with atleast 2.5 cubes of space and tuned to 32 htz thus box is roughly 1.5 cubes and tuned high to 38 htz ur sub on this box will take away about 35% of the output sound of ur sub. This box is half the size u need for a big american bass elite sub american bass i think recomends 2.5 to 3.5 cubes but they recommend a big 3.5 cube box tuned 30 to 32 htz throw a 2k amp on that sub and it will do work.
