I am wanting to wire a cab to use with my Shuttle amp, the manual say wiring is +1-1 so I take it that they are the only terminals used out of the amp so, I need to connect the wires in the cable so that is is +1-1 between the amp and speakers. I have a Neutrik cable with 2 wires but they don't match up with the +1-1 on the female connectors, the male Neutriks are NL4FC and the female connectors have 4 spade terminals. Do I need to change the wires on the male plugs so that there is a +1-1 connection at both ends of the cable. Thanks in advance
