wiring in series with a vertical bi-amp setup

Does anyone have any experience running speakers in series while doing a vertical bi-amp setup? I'm going to give it a whirl this week and see how she blows.

Might I add, I'm very impressed with vertical bi-amp sound quality when running two speakers (one per amp), but am wondering if anyone's done vertical bi-amping in series and what they have to say about it.

Cheers,
Brad
