Another Bi-Amp Question

I have B&W 805's for front speakers and a Pioneer Elite A/V Receiver (VSX92THX). The speakers max power handling is 120W and the Receiver max output is 130 watts into all channels. Here is my question- I can biamp the fronts using the surround rear speaker outputs. Would I need to worry about frying my speakers? In otherwords, would the B&W handle max 120W into each driver? Or, would I be putting out (max ) 130w X 2 into each speaker?). Sounds awesome the way it is but if I can grab a bit more power w/o damaging anything, why not? (It is an HT system only).

Thanks,
