Sure you can use them for rear channels. It has been my experience that rear channel amplification does not matter a whole heck of a lot. I have had very expensive amps (and great sounding) amplifying my rear channels, and I could not tell the difference between them and a SOny 5*100wpc solid state amp.
Going with Maggies, I would think power as far as amplification goes. There are several threads here about powerin Maggie 3.6s.
Anyway, I have owned Maggie 3.6s, and I am not convinced that they are a good choice at all for home theater applications when compared to a nice dynamic box speaker. Maggie speakers in general are just not that dynamic. People who say they are... well... have not compared them side by side to nice box speakers.
I run my HT system through my 2 channel setup. Look at my system here at Audiogon and you might get some ideas.
