The inverted pair simply need to be "re-inverted" at the speaker or amp speaker binding post end (it won;t work to reverse the interconnects, etc). Simply switch BOTH left and right speaker wire red and black leads (red on black, black on red) but ONLY at the speaker or amp end, not BOTH.
Inverted outputs were installed to account for amps that invert the signal (some tube amps), but the simple speaker wire swap takes care of it.
