What ratio of power in tri-amp system ?

In order to better utilize equipment , is there a formula or chart somewhere that recommends what wattage power amp should be used for each power amp in a three way system ? I realize that crossover points and speaker component's individual performance spec's would cause great variation , but is there some kind of rule of thumb for a starting point ? Is this too vague a question ? I have a PA system with separate cabinets for all speakers and would like to know whether I have enough power for the speakers or need to get more speakers for the power .

I have an active bi-amp system.

Quality is actually more important than quantity.

I personally use Krell amps, all of which have the same gain. Since mine are different models, I use the best one for the mid/highs and the older one for the bass. If I had three different ones, I would use the best one for the mids.

I did see a set-up with the B&W Nautalis, which is a 4 way speaker. They had all new amps. They used the biggest for the bass and progressively smaller for each speaker up to the tweeter.

I hope this helps.
