Internal volume (cu ft) is calculated by multiplying the dimension, in inches, of the width by the height by the depth and then dividing by 12 times 12 times 12 (1728). The Bike Party box has a top and bottom internal cubic area behind the bass driver. The internal volumes are calculated below.
Top
3.6 x 17 x 10.3
630 / 1728 = 0.365 cu ft
Bottom
9.6 x 17 x 12.2
1991 / 1728 = 1.15 cu ft
Total Internal Volume
1.52 cu ft
