    Box help for old school 15

    Im planning to put a rockford fosgate Pch-815 in a 92 celica hatchback
    heres the link to the spec sheet

    i think sub up port back would be the best application for this but just want to make sure

    also what kind of box volume do i need maybe 2.5-3 ft^3

    box specs using RE calc

    W:32 H:15 D:16 Wood thicknes:.75 Port W:3 Port L:8

    Total port length:25.5
    Port area:40.5
    Box volume:2.85
