I think the point many of us are making is to make sure he understands the signal-flow employed here. It sounds like he doesn't quite have his ducks in a row in this regard and that can be a problem. It's not that he can't do that, but we're all just kind of policing it! No offenses meant, but no presumptions are being made either.
What if he were to write back saying he'd toasted his amp? Then we'd maybe feel a little remiss...
EDIT: We didn't say that (I don't think)- just that he can't go to another power amp from the Superfly's speaker-out.
I understand what you are saying.
And, I agree that it sounds as if the OP does not have his ducks in row.
Only point I was making is that the OP needs to know that when hooked up as described, he will have two active cabinet power sources available if necessary.
I also strongly suggest that the OP finds someone in his local area to assist him and talk him through/show him the set up step by step to avoid confusion.
