Tips:
In the case of sufficient audio input and sufficient power supply voltage/current, there will be sufficient 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 adaptor power supply is greater than the actual working power of the amplifier!
