1) Just bi-amp my fronts with the 806x using two channels per speaker? Then, I could use either the two 100 watt channels from the 405 for the rears, or bi-amp the 405 using the 100 watt channels for bass and the 50 watt channels for the highs. Either way, I would not be using the 110 watt channel on the 405.
2) Bi-amp the fronts using the 806x for bass (i.e. 133 watts) and the 405 for the highs (100, 110, 100 for L,C,R) and run the rears just using channels from the 806x - this would leave one channel of the 806x unused and the 50 watt channels of the 405 unused.
3) Bridge the 806x into three channels of 360 watts into 8 ohms each for the fronts and center and use the 405 to power the rears
Since both of these amps have this power steering feature, theoretically wattage would not be wasted with empty channels since power would be steered to those channels that need them.
I know this is a bit complex, and I am a newbie at this kind of stuff, but any advice on an optimal configuration?
I just want to get the most quality out of my speakers, especially for music. This is all in a fairly small room about 14'x10'
