Yeah, amps don't like having to run voltage out one set and current out another set of outputs....they'll do it, but the outputs will be unbalanced and the coils(in the transformer) will not like it. The only amps that will be ok in that scenario will be the ones with true 4-channel amp technology, which is technically 4 single-channel amps in 1 case.
