There are two RCA subwoofer outputs that are internally wired in parallel. You can use either one to feed the signal to a powered subwoofer. Here are various configurations you can use.

Use standard UR RCA jacks to feed the signal from both outputs to any powered sub with UR RCA inputs. Please note: since both outputs are putting out an identical mono signal, it doesn’t matter which one you hook the left and right RCA jacks to.
Use a monoaural RCA cable to feed the signal from either jack to any powered subwoofer with,an LFE (Low Frequency Effect) RCA input or a single RCA sub input.
