So I have been happy with a 3 speaker setup for some time now (left/right/center) but my uncle was cleaning out his garage and was going to be tossing an old Sony subwoofer. Since I did not have a sub, I decided that I would take it home and plug her in. To my dismay it seems as if this was either a proprietary setup or just even older than my receiver (which is over 6 years old itself). What it looks like to me, is that the sub only accepts RCA inputs while my receiver only accepts a Monaural connection. I didn't have my camera handy so I ripped some images off the web to show you exactly what I m facing. Any suggestions to getting this working or is this just trash? Thanks
