I did at one point, its pretty simple. Just use some MDF and seal it, If you know how to do ports and stuff you can do that. I ran a tub width square ported box I made for a kicker L7 12in. I don't have any pictures though sorry, it was about a year ago. I made a plexiglass cover for the top and a sectionion to put the amp in, and painted the plexiglass black and left the rectangle over the amp clear to see it, and had the sides open for the amp to breath.
