Using old McIntosh amp MC2200 in bi-amping??

Hello all ...

Coming up to speed on the electronic concepts in play with hi-end audio. Particularly choking on speaker load / amp impedance dynamics. Curious what an old McIntosh MC2200 (circa '79) does for the woofer end when bi-amping B&W Nautilus 804's. I see where this amp has separate positive speaker terminals for 1, 2, 4, and 8 ohm's. Guessing I would use 8 ohm terminal into the 804 woofers, but wanted to run that past you all before doing so. Is that the right choice? Is amp not suited? Will speakers explode? etc.
