Default Calculating watt requirements for multi-mode/tri-mode operation?

I read that most bridgeable amps can handle multi-mode even if the amp specs don't say so.


If you do this with two full-range speakers, bridged subwoofer, and crossover, how should you calculate the wattage requirements for each speaker, based on the amp specs for bridged and non-bridged operation?

Do each of the speakers have to be rated for the same wattage as they are when used NOT in multi-mode, or can they be less according to some formula because the crossover is dividing the power?

Default You can use a non precise idea.

Because, watching on scope, you will see that, bass amplitude is normally 60 percent, medium frequencies 30 percent and treble 10 percent.

Using this base, you will not be too much wrong....but, if your amplifier use on compressor, this way things turn complicated.

Because when you reach the threshold of clipping, it will maintain this bass level (normally the bigger amplitude one) and you increasing volume, you will give more level to the mids and highs.

This situation is dangerous, because you can have full power on highs!

Good luck!
