Reading through the manual it does indicate bridging will almost double the power. I haven't seen the impedance chart on the M60s and if they dip low enough it could present problems in BTL mode.

I sure enough know one thing, my Onkyo runs pretty hot even running 8 ohm speakers. Running in BTL mode is going generate a lot of heat in the amp if it truly does real bridging..
