i have a few questions about bi-amping, and if its any help, bi-amping from a receiver that has the capability to bi-amp with the front/surround back terminals.

first off, how much power is actually going to the speakers when they are being bi-amped. if it was a receiver with 130 wpc, is it 130 watts to the lows and 130 to the mid/highs? or is it a little less, as if it were just a 4 ohm speaker (~250 watts)?

also, i know seperate amps are always going to be better, but would you guys shy away from bi-amping from a receiver?

asking because a pair of fronts i want can take 50-200 watts, and i dont want to put too much power, yet still want to bi-amp. i know more power is better than less, but i would like to find a sweet spot of power with a pair of fronts and the receiver im bi-amping from.

thanks
