Yeah, Micah; but I think it's a bit more interesting than Mike Drew vs Larry on how to inflate bike tires in the other thread. I'd suggest forgetting this "pushed" terminology; an amplifier doesn't force a speaker to take any more power than it wants for a given sound level at a given instant. For a comfortably loud level with speakers of typical sensitivity this is about 1 watt and doesn't vary regardless of the maximum output capacity of the amplifier.
No, the power capacity of the amplifier isn't divided according to the number of drivers in the speaker. So, for example, an amplifier that could output 200 watts if necessary could send that maximum output to any of the drivers that needed it.
