so hard to write with a sub...

find the rolloff freq of your monitors. ie) 47hz.
set the cutoff freq for the filter on your sub to that freq apx - if anything a touch higher imo, although some will argue.
(if your monitors have adjustable freq, have your sub cover as much low-end as possible - if your monitors cones don't have to cover bass frequencies they will represent higher frequencies more accurately).
sit in your chair facing forward and have someone move the sub around your room while you listen. you want to avoid any areas where standing waves are attenuating or accentuating the bass too much. use test tones going up and down a bit if possible to ensure your assessment is accurate for a wide range of bass tones.

next, have your buddy flip the phase swith back and forth on your sub. leave the setting at the louder of the two. what you're doing here is ensuring that your monitors and your sub are not out of phase. if your sub and monitor cover the same freq and there is a pure sine wave there, for instance, it will be percieved quieter than it is because your sub would be cancelling the tone out of your monitors.

hope that helps a bit. room treatment is really important when using a sub.
