4806 + Amp
I agree that the amp is probably overkill with your 4806.
Consider connecting the 4806 directly to your speakers and using its very capable internal amplifiers. If you are happy with the results, return the outlaw amp, they have a good return policy. Use the money towards a new display, sub, DVD player, acoustic treatments, etc.
If you have very inefficient 4 ohm mains, then you might want an outlaw 2 channel amp or a couple monoblocks for the mains and let the receiver drive the rest.
