They are dual 4 ohm VC's so it would be better to run both of them off of one amp (like the Bash 500 you mentioned)
This amp might be a little cheaper and easier to get rid of the subsonic filter (which you don't really want)
Since you do not want to build a box I would say try to find a prefab box that has ~3.5 to 5.5 cu.ft. internal volume. I doubt many car audio boxes will be that big for only 2 10's as they call for less than 1cuft each in a car, but you might get lucky or you can mod some 12" or 15" boxes.
