DIY REL subwoofer cable

[Brunes]

I have some leftover CANARE 4S11 cable that I would like to use to create a short sub woofer cable for a REL T Zero.
I only need 3 of the 4 wires, so what should I do with the remaining 4th core?

Leave it and don't connect it to anything or join 2 together and use it for the minus/ground
Thanks!

for CANARE 4S11 Star Quad loudspeaker cable, connect the 2 Red wires to one of the amps terminals and connect the 2 White wires to the other amp terminal.

Thanks, do I ignore the ground or use the cable shield for that ?

What are you trying to connect?
CANARE 4S11 Star Quad is a power amp output to loudspeaker cable. It has no 'ground', it has no 'shield'.
Are you trying to make a RCA or XLR line level interconnect cable?

One of these or this

Now I understand. It's a special cable.
Looks like they doubled up on the one with the Black color code.
But I don't know which Neutrik Speakon pin that might be.
