Bobby Page 13 in their manual shows true biamping(external crossover), but either way, you are not able to add the power of the 2 driven channels on the speaker to achieve 400W, you are simply running 200W for each section of the crossover you are feeding the power to. Bridging the amp is how you achieve double the power or 400W/channel. I didn't look, is this amp even capable of bridging?
I also wonder how Sunfire/Carver is able to claim/achieve a true doubling of power into 4 ohm loads when nobody else appears to be able to?
