yeah, its a 280zx 2+2, i should be done by the end of the week. As for specs on the box, its built around a single infinty kappa perfect 10.1, (i made a 2d cad model of the sub, and designed the profile of the box around it, with VERY tight clearences, so this box will not work for very many subs). Its built from 1/2" mdf, should be very stealthy, has a volume of 1565 cu. inches, and is sealed. Mine will be wrapped in vinyl to match the interior, and will feature a cloth grille, also color matched to the interior. It does not take up the entire width of the hatch, so later when it warms up this summer, i'll fab some fiberglass panels to stretch from the box to the sides of the interior, and also cover the amp.
