Quick NU4-6000 wiring question

I have the amp running my two mains and two subwoofers. Nothing is bridged. I currently have the mains on A and B, and then the subs are on C and D. I noticed today though that A and C bridge, and then B and D bridge. This would seem to indicate that A and C are essentially one amp, and B and D are the other (since this is basically two nu3000s in one case).

Since my mains are 8ohm and my subs are both 4ohm, should I be running like impedances on A and B, A and C, or does it not matter?

No, A and B bridge together and C and D bridge together. It just assigns A and C as the positive side of the speakon, and B and D as the negative.

But it doesn't matter, each is an individual amp channel, all 4 channels are identical. So it doesn't matter what impedance is on what channel. And they all share the same single power supply.

That makes sense. I wasn't thinking of it in terms of how to wire it when bridged. I just wanted to be sure I wasn't doing anything that was making it work abnormally hard.
