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