sub boxes

hey guys, I know it wouldnt really be custom depending on how u look at it if u just go buy a box for ur specific car, but im lookin for a custom box for a 99 civic. I really dont care how fancy it is, i just dont want the boring square box bouncin around and lookin like shit in the back of my car. Any help finding a place that would sell one or anyone that has one would be great.
