Bi-Amp Power Rating


If this has been discussed before, please point me in the right direction.

I've been looking to upgrade my speakers to a set that can be bi-wired. My question is this... If the speakers are rated at, say, 200 watts/channel, and I'm powering them with an amp that has an output rating of that same amount, what happens when you bi-wire them? I mean, if I bi-wire the speakers, presumably bi-amping them, wouldn't I have to halve the power of the amp? Otherwise, wouldn't the speakers be receiving, theoritically, 400 watts/ch? Thoughts? Or, are the power ratings of bi-wireable speakers already taking into account the double dose?

Thanks

Why are you doing this? Biamping will not offer any power advantages over single-amping if the single amp has adequate power to fully drive the speaker. As for what power the speaker can handle, it doesn't change.
"OTOH, I am sort of interested intellectually in the actual answer; i.e., for 2 amps rated at 100 wpc each, how much power are you delivering if you vertically bi-amp?"

The answer depends on the frequency distribution of the signal and the power handling of the upper and lower frequency drivers.
