Hi, I just got myself an av receiver to set up my surround sound system. However, my amp is left over from an old all-in-one speaker package and it has 2 wires (red & black, like normal surround ones) coming out of the back. Unfortunately my amp has a single hole (which I think is standard). So, is there any way to connect them together? I was hoping I could just add a kind of connector to the wire so that it'll be able to slot into the amp. I really hope I dont need a new amp aswell Thanks.
