Typically it wouldn't double the output (which would add 3dB headroom) because the maximum wattage available per channel drops off somewhat when more channels are active. Probably adds about 2dB. This all would vary by content, as well, so I don't know there is a cut and dried answer.
I've never tried it because my speakers are not designed for it, but my daughter did it with her Paradigm Studio 100's and likes it. I haven't been out to the left coast where she lives for a few months, so I haven't heard for myself.
In any case, the whole subject of bi-amping is fraught with controversy. Some adamantly insist it is a complete waste, but some speaker designers say it isn't if the crossover is designed with bi-amping in mind. Hopefully we won't open that raging argument here.
