Hello, This is probably a very simple question but I'm very new to this home cinema thing so please bare with me. :) I've just bought a Yamaha RXV365BL AV Receiver and a Q Acoustics 1010i 5.1 speaker package but I'm not sure what type of cable is needed to connect the sub to the receiver? Here is a picture of the back of the receiver: http://amazon.bellmktg.com/Yamaha/Receivers/RX-V365/rxv365bl_back_large.jpg
