Dual Voice-Coil
The unique Dual Voice-Coil design allows both left and right channel sound from just one speaker. Simply hook up both the left and the right channels to the special terminals on the speaker. Hook up one channel only, if the speaker is to be used in a conventional stereo set-up.
I found this on jamo site hope that will help you

Hi,
You don't need such cable, although you can use it if you have one. If receiver has only mono SUB output (as majority of receivers have), you just connect it to the Left socket on the Sub and it will work.

Using the Y cable would probably cause that you will fed the same signal to both left and right sockets, but half the intensity (you would divide the output from receiver by 2). So in the end the Sub would receive exactly the same signal as when using normal straight cable.
