I have two ten inch truck boxes for sale. The first is a custom wedge box that would be perfect for a taller person. It dimensions are:

Width: 18 1/4"
Height: 16 1/4"
Top Depth: 3"
Bottom Depth: 8"

The box is great for limited space situations like a Ford Ranger. It was used for 3 weeks before my sub went out and I upgraded to a 12" sub. Some deeper mounting speakers will not fit due to shallow top depth. $35

The second box is a brand new, never used Audio Innovations 10" box from Best Buy. I bought it, got it home, test fit it while it was still in the plastic, and decided not to use it because it took away a little too much leg room. (I'm 6'1"). The dimensions are:

Width: 19 1/4"
Height: 14 1/2"
Top Depth: 5 3/4"
Bottom Depth: 9"

It comes with the rubber baffle and directions and has only been out of the plastic to take these pictures! - $60
