place them such that neither of the subs is directly near one of the port openings. also they should be somewhere onthe outside of the box where they have room to breath. at 20 inches long that will give you a tuning freq of about 32Hz. if you use the psp flared 6" which come in 17" lengths (they can be made longer by buying more pieces) then the tuning freq would be about 35Hz.
