Sure, I would love to see what you've got in mind. My only restraints are that the box be 36" wide, less than 20" tall, and less than 45" long overall. 2 cubic feet is ideal for internal volume.
Since I don't know any measurements, nor the model number of the kenwood subs to even get specs off, I just based this off the measurements you gave me for maximum dimensions. Port would most likely be a T port....and mostlikely work best on the side of the box. I was making the box and realized what time it was...have to work. So here is my idea.
