bi-wiring center speaker

All,
My center speaker is bi-wireable and I have a stereo amp dedicated for it. I planed to bi-wire the center speaker by hooking up one channel from the amp to the woofer connection on the speaker and the other channel to the tweeter connection of the speaker. My concern is that now each of the amp's channels will see a different load and as I vaguely remember reading somewhere that this is not healthy to the amp. Can somebody help confirming if this is an ok thing to do or not?
Thanks,
Chuso
