yes. models very nicely in a 1 cubic foot enclosure per driver, but you could go smaller, less than 0.5 cubic feet might be getting a little small.
anywhere from 0.5-1.0 cubic feet gives a -3db point of around 55hz. in a car, cabin gain will really extend the -3db point.
and 100 watts per driver in the 0.5 cubic foot per driver build is ok, but in the 1.0 cf per driver, that is a little too much. only 50 watts or so per driver would be required to push the driver to its excursion limit.
