sonos connect amp sub output not powered

I recently bought a gen 1 sonos connect amp and after using it for a few weeks with 2 ceiling speakers I decided I needed a subwoofer. So I bought a Samsung wireless subwoofer and took it apart down to the speaker wire ports under the cover I then connected this to an rca adapter and plugged it into the sub output on my amp. I waited for a wile for it to show up and I also rebooted my system but no sub appeared on the app and the sub did not make any sound when playing music. Please help me make my sub work

    Ah right, the connection labelled Sub is for active subwoofers, not passive subwoofers. If @William Etherington-Smith really connected that to “the speaker wire ports under the cover” and not to the amp in the Samsung, that’s the first of his problems.

    I’ll connect it to the amp input unposed to the speaker wire inputs
