I need a box design and cutout sheet for my temporary setup, its 1 18" FI Q getting around 1500rms off of a GP3000D. i would like to give it around 8 cubic feet and tune to 35hz. My max dimensions to work with are 40"W X 20"H X 25"D but it does not have to be near that big. I would like sub up and port back. I can paypal over some $$, but need the design ASAP. Pm me if you feel like helping me out.
