    in reply to: 8-22V to 1-15V regulator #9419

    Hello Don Lundgren,
    This problem may be caused by the self-check of the car.
    When start the car, there will be a process of self-checking,which the voltage will reduce.
    When the input voltage is lower than the output voltage and no differential pressure, the output voltage of the product will drop, too.
    Bsides, it is a little hard for this product to output 10V.
    Because the voltage of a car is about 10V in general and there must be a 3V differential pressure between the input voltage and the output voltage.
    Hope this can help you.
    Best regards

    Hello Dudeguy21,
    Sorry for our late reply.
    Could you please tell us the current of your power supply?
    This problem may be caused by that the current of the power supply is too low and the power is not enough to drive the amplifier when the volume is turned up.
    Could you please try to use another power supply with larger current to check if the amplifier work normally?
    If not, please feel free to write back to us.
    Best regards

    Hello Don Lundgren,
    Thank you for your reply.
    Did you adjust the output voltage to 10V?
    What do you mean that you remove power?
