If you choose a custom built sealed, be sure that it is made out of MDF (Maximum-Density-Fiberboard) and sealed with an all-purpose oil based caulk. The sealed box can be made to fit anywhere desirable, if custom built. If it's a standard box, rectangular, wedge, or trapezoidal shape won't really made a difference. Either way, since the subs are in the cabin and not closed in a trunk like a car, the bass quality should be exceptional.
