Tip:In case the audio signal input is large enough and the power supply voltage/current is large enough, only then 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 ensure that the power of the adaptable power supply is greater than the actual working power of the amplifier!
