" I thought your suggestion of 100uF cap across the sub and running it from an unused channel would work fine."
That's not what I said and you can't just do that. It is a twp channel amp, and even if it did have separate amps for the B speakers you still can't do that. The cap will blow up if there is nothing to limit the current through it. Through a resistor is a different story.
Whether AC or DC, amp outputs should not be paralleled unless they are specifically designed for it, and some are but most are commercial. On a regular amp, the DC offset is controlled by feedback. If you attach what maight be a DC source or sink to the output that prevents that feedback from working, the amps work against each other leading to high dissipation in the outputs. And you might not even hear it.
