unusual setup for sure, things make so much more sense if they are hooked up as intended and designed.
If your mains are mono, just use the left or right output, and a separate mono mix for subs. Easy peezy. 🙂

For a small mixing system without many outputs, this was somewhat a common thing to do back in the day because the left and right main outs were saved for stereo recording.
