[Need to build box]

Sorry I kinda guessed at the space but i just measured it and its in the back of a van and the measure measurements are as followed: from back of door to the back of seat i have 18" max and from wall to wall keeping in mind corner panels i have 48" max and from floor to the middle of the back of seat is 26" can be a couple inches taller if needed. Sorry for wasting yalls time before now i think there is enough info to give me 4 cubic feet on each side. The specs of the (2)p3-15w speaker are here
