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 have a B&K Sonata 5ch amp,  150W×5 which I used with an active crossover, it has outboard trim but I used the gain on the X-over to set the levels and the x-over points
That's how it's done in a pro-audio environment (for good reason)
Sounded super clean and strong
I would sell it if you're interested
