Be aware that you cannot use an instrument cable to connect the cabinets. The cable is nit designed to take the high currents involved and neither are most jack plugs. I can make you a cable or you can use some of the reputable companies online. To ensure you know that this is a speaker cable, I suggest a jack on one end and a Speakon on the other. Use either Neutrik, Cliff or Amphenol speakons and Neutrik Jacks,
