14. Tips: Only when the audio input is sufficient and the power supply voltage/current is sufficient, there will be sufficient output power! ! ! The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power! ! ! Please ensure that the power of the adapted power supply is greater than the actual working power of the power amplifier! ! !
