Which amp to Bi-amp my Maggie 20.1

I am considering bi-amping my Maggie 20.1s’ I have two amps, one has 1,000 watts into 4 Ohms and the other has 500 into 4 Ohms (both ICE amps). The Maggies are 4 Ohm speakers. I will be bypassing the low pass crossovers with an active crossover at 130 Hz. 15 dB/oct., but I will be sending a full range signal into the mid / upper crossovers to power the upper half. My question is should I use the 500 watt on the bass panel and the 1,000 to the upper so that I won’t risk clipping into the mids and tweeter? I don’t think clipping will damage the bass panels. Please don’t think I going to “blast” the sound at killer high volumes, the amps my never clip, it’s just that the Maggies are very inefficient. Also since I am bypassing the low crossovers doesn’t that make the bass panel easier to drive? So anyway please give me your opinions and reasoning over which amp goes where? Thanks.
