Hi cosmicjazz
So keep in mind that those connectors are there purely for convenience. Besides the switch, there is no extra circuitry. You don't get more of an amplifier by using A+B.
So it is up to you to ensure that the impedance of the A and B speakers does not drop below the amplifier's recommended minimum if used simultaneously. This is typically 4 Ohms.
One possible use is to bi-wire. That is, remove a speaker's jumpers and run a separate cable to each input.
But again, you don't get more amp.
Best,
