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?

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? I don't know the hows, but that kind of increase is common[ly claimed] in the mobile AV industry when moving from 4 to 2 ohms or to 1 ohm. Funny to hear all the issues with 4 ohm loads in the home AV side when DC amps run down to 1 ohm pretty often. I'm sure I'll get slammed with a ton of tech-speak as why this is wrong, but 2 ohm loads are stable in my car - yes I used a meter not a manual to make that claim. But that is not what is diagramed here. Using separate channels you would not get the resistance decrease of adding more or lower ohm speakers as I am describing above. That picture should be 200 to each channel as the amp will just push the 8 ohm load it has in front of it, regardless of whether that load is in the same box as another 8 ohm load (or whatever the loads are). Of course, separating out the speakers may mean you have higher loads, thereby reducing the power output to each…in my weak theory anyway. (Let the tech slam begin.)

Thanks sirquack, that is a very clear and understandable description of what true bi-amping actually is

car amps have WAY large capacitors in them (i think)... maybe that lets them handle lower impedances easier?

Most car audio is set up for 4 ohm loads, so a dip into the 2 ohm range is not uncommon. I have always considered running a car amp to drive the M80s, because they are built , or at least appear to be built, stonger and cheaper than home audio.

Do they mean to bypass the speaker internal crossover and then set the external crossover to the same freqs as the original internal was?

That is correct. Or adjustable external crossover. A whole lot of trouble for a dubious possible improvement.
