    “Vin+” is still connected to power supply”+”. “Vin-” is connected to power supply”-“. That is to say, you need to move the black wire from left large screw to “VIN-”. The black wire is as showed in the picture.

    Hello Noah,
    We don’t limit the input current for this amplifier. You should choose suitable input current as needed. Please kindly think about if the input power supply can offer enought power for your speakers.

    Hello William Scully,
    We just consult this problem from our technicians. We are sorry we need to correct one mistake. When measure small current, the “VIN-” should be connected to negative of power supply, that is to say we just move the wire(the black wire in figure 1) from left large screw to “VIN-” “VIN+” is still connected to positive of power supply.Sorry for trouble caused on you.
    In addition, please note this wiring can be only applied when the current is below 2A.
    Best regards.
