Okay, I know some of you are sick of reading this question, but since it's new for me, I'm asking it again.

I have a Two-Channel C. Two speakers outs, switchable impedance. I just got a PRS Big Mouth cab, 8 ohms. I have an Orange 4x12, 16 ohms.

Currently, they're stacked but not running together. If I would want to run them together, would I use the 8 ohm output setting? It seems to me I wouldn't want to pump 16 ohms into an 8 ohm cab.
