well ok i can do that, the trunk space is L 33", D 43", H 21", and i could go a little higher. its a suv so i have a nice hatch. I would like the speakers facing up and the port to the rear at the hatch. Nothing fancy just a rectangle box. as for music all types, from techno, to heavy metal with a lot of double bass, or even some bass mekanik. as for the sub spec i dont what u want, I mean hey i could write the whole owners manual.
