Yeah there's a few that have run the JL 6 channel, in fact there was a few for sale not too long ago.
It is moderate in power output, but is sufficient for normal listening.
I don't mean to plug a classified ad, but did you see the A/D/S 6 channel beast that came up recently? $400 OBO shipped, and has onboard digital crossovers. Pretty sweet, IMO.
