I used to read somewhere that when establishing a bi-amp configuration, the power could be calculated to new power, i.e., a bi-amp system employing a 60W mid/high amplifier and a 60W woofer amplifier can equal or exceed the performance of a single 150W amplifier driving a speaker through its passive network.
Is there a formula for calculating the new power when setting up a bi-amp configuration?
e.g., employing a 70W mid/high amplifier and a 105W woofer amplifier can equal or exceed the performance of a single .... Watts amplifier, or employing a 65W mid/high amplifier and a 120W woofer amplifier can equal or exceed the performance of a single .... Watts amplifier.

This page i did a couple decades ago covers this subject to at least some extent: https://www.t-linespeakers.org/oddsends/biamp/Index.html

It would be interesting to figure out the crest-factor as a function of frequency band for a range of music types, although its quite a lot of processing if you want this as a function of the lower and upper cutoffs and filter order... The motivation being to minimize the chance of clipping and simultaneously reduce total amp power (or increase SPL at the speakers!), and make meaningful decisions about number of drivers and amps
The reason I'm curious is because my friend is establishing a bi-amping system, using a six-channel car amplifier. He bridges ch3 & ch4 for the left woofer, and ch5 & ch6 for the right woofer. The unbridged channels, ch1 & ch2, drive mid/tweeters. The power amplifier has 50W per channel and will gives 100W in bridged channels. So, I'd like to know how much power of this bi-amp system when compared to single-amp operation.
