Distributed Bass Array configuration

Please, I don't want to debate the merits of the DBA nor of those who espouse it. I am considering adding two more subwoofers to a system that has two already. To those who use a DBA,I am interested in how you have configured them, specifically--
  1. Do you run in mono, or do you split the array to run in stereo?
  2. What is your approach to setting phase (delay) among speakers that may be facing different directions and are different distances from the listener?
Thanks!

Thanks Duke.
 I did that with self powered subs and what I found was that the best spots that where candidates for Sub # 1`s position ended up being where Sub # 2 went and the third best spot s where Sub # 3 ended up.
So in this room, there didn`t seem to be a need to go through the Sub in the listening spot routine after all.

Question:   
When using the crawl method and picking the best spot for Sub #1
are you supposed to then power up Sub #1 while crawling for Sub #2`s best spot and so on with each sub thereafter....??
