You put two 11ga conductors in parallel for the + and -? That's equivalent to 8ga I think.

I was only thinking to use a 2 conductor 12ga SOOW for my slave sub.

Correct, that's comparable to a pair of 8AWG wires, but the 4x cables are more common, and the jacket is more round and terminates more easily. Since the internally powered sub only has ~2' of wire, it's good measure and allows longer runs. The 4x12 in-wall wiring has a much thinner jacket if the diameter of the wire is a problem for any reason or if you need a white or grey jacket.

All 4 pins of the SpeakON are connected with +1/+2 in parallel along with -1/-2, so just use 4x 12AWG. While for 70% of the range it doesn't matter much, remember the lower the minimum impedance, the more the wire size can matter. For the small cost difference going to heavier copper, it's silly to waste power in a speaker cable.
