I am trying to connect a subwoofer to my STRDN1080 amplifier and am having problems. According to the STRDN1080 instructions you need to connect a subwoofer using a monaural cable but the subwoofer doesn’t have plugs only bare wires. I bought a speaker wire to audio male RCA connector and plugged this into the STRDN1080 as suggested but I don’t get any sound out of it. When I run the automatic audio set up I get a message to say my subwoofer isn’t connected properly. I can hear it faintly though. Does anyone know how to resolve this?
