I've got a 7700 and I like it a lot. Drives the M80v2's just fine. Why skimp and go with the 7125? Though 125 watts from the lower end Outlaw may be enough it is always a good idea to have "headroom". Remember the M80's are 4 ohms and you need something that will drive that cleanly. I assure you that the 7700 does. Also, why 4 M80's? You certainly don't need them for surrounds?
Go with the 8's all around. And finally, go with the EP 600, not the 500. Low ceilings yes but quite a volume of room. And the Outlaw sub?
again...Why? Seems like for the same money you could get 2 M80's. 4 QS8's, a 150 and a 600 and be far ahead of the game sonically. Do some more research and you'll be happier in the long run.
