Tip: When the audio signal input is large enough and the power supply Voltage/current is large enough,There will be enough 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 make sure that the power of the adapted power supply is greater than the actual working power of the power amplifier!
