It would work well in 4 cu. ft. tuned to 21 hz with a full length 4" flared port 17 " long. With the coils wired in series for a 8 ohm load the sub would reach Xmax at 150 watts with a Hi-Pass filter (rumble filter) at 18 hz. The Parts Expresss Bash 300 amp would fit this perfectly.
With room gain you can expect 106 - 108 db at 20 hz. You could gain another 3 db at 20 hz by increasing the box size to 6.5 cu.ft tuned to 20 hz using the same amp. The port length would be 11 inches.
