Woo-hoo! Six subs! Color me green with envy! I only have five!
As far as the distributed bass array effect goes it has nothing to do with which subs. No matter what or how big or how powerful the key to them all is to create lots of different bass modes, which you do by distributing them all around the room.
Since the general idea is to create lost of different bass modes the usual approach is to put the speakers in as many different and asymmetrical locations as possible. So in other words you would do something like put one on each wall, but different distances from the corners, and then since you have six put the other two wherever you think they will be less like the others. Or wherever they will fit! Ha! Life is rough!
Seriously though, if you read the papers the good news is the more you have the less it matters where they go or even what they are.
As far as amps yes the Dayton is the go-to amp. I run two of those, one per each pair of 10" subs, plus one Talon Roc powered sub. There is some benefit to using two amps but not as much as I thought and not enough to recommend it. Mostly you just get more flexibility in being able to control subs in pairs instead of all together. But the more subs you run the less this matters so wouldn't talk you out of it but see no need to recommend it either.
When connecting the speakers just keep in mind the total impedance. Best practice is to connect them whatever will yield a total of around 4 ohm, and then if possible also try them at 8 ohm and/or 16 ohm. While everyone knows you get more power into 4 ohms most everyone who has compared finds 16 ohms sounds better. The tradeoff seems to be you can play a few dB less loud, but the bass is more articulate at the higher impedance. Try it and see.
Also when connecting save your money and use regular hook up wire. Expensive speaker cables definitely not required. Duke told me this and I found it hard to believe even though it was Duke but he was of course right. Cheap speaker wire and interconnects are all you need for really great bass. Save your money for the stereo mains where these really will make a big difference.
