I have never seen one of these amps however it is probably just like the rest of the remote bass control ports out there. Just get a phone cable and cut the one end off. There will be four wires. The inside pair get tied together and soldered to the wiper of a potentiometer, the outer wires get solder to the outer legs of the potentiometer. I believe a 600 ohm pot is what i used for my phoenix gold amp. Good luck
