You say connect it by RCA but it looks like a coaxial connection to me, the same thing my current Onkyo 606 has that my sub is connected to. maybe i'm misunderstanding something.
Though I get that I should plug my sub into one of the pre-out connections. Thanks. I would have hooked it up to the multichannel one if I wouldn't have asked.
I would call RCA a coaxial connection. But people usually say RCA when they mean an RCA plug terminated cable (RCA plugs originating as a phono connector and named for the company.) RCA terminated connections are used for many purposes such as line level analog audio, digital audio, and video.
Coaxial used without a context is often used to refer to RG-58 or similar cables.
In this case, the subwoofer output jack is designed for RCA terminated cables just like those freebie red/white cables, but it's mono.
Any RCA terminated cable would work.
The important thing is to not confuse the subwoofer OUTPUT with the subwoofer input grouped with the other multi-channel inputs. This is all to easy to do when wiring with limited light in tight confines (done it myself.)
