yeah thats how you would wire it.
i cant tell what brand that is, but i dont recognize it.
as far as ported vs sealed.
ported can have higher output (get louder) especially at or around there tuning frequency.
sealed boxes usually have tighter sounding bass. sealed boxes are also generally alot smaller then ported.
try contacting the manufacture of the sub and see what they reccomend for that sub, or maybe look up there website.
