What’s the Right Power Amp Ratio For Bi-Amping?


Is there a “golden rule” or rule of thumb when selecting amplifier power in a bi-amp setup? It seems to me that the power should be apportioned according to the demands. Since most of the energy consumption  in sound reproduction is by lows, it stands to reason I should use a much more powerful amplifier for lows than highs, but what ratio of power? 2:1? 10:1? Is there a wrong answer?

I am using one stereo amp on each speaker. Left for mid highs and right for bass cabs.  The meter is always higher on mid highs.  Same amp.  Crossdover point between upper bass driver and lower mid driver is 230hz.
