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