The Y cable is to split the single RCA cable to the receiver L/R speaker input.


Oops, think you may have your wires crossed... are you sure you have a stereo 1/8" to RCA cable? It should have two RCAs on the one end and a tip/ring/sleeve 1/8" at the other end... if the ring isn't there, you've got a mono cable.
