Tips.
There will be enough output power only when the audio input is enough and the power supply voltage/current is enough!!!!
The higher the power supply voltage, the higher the output power, the lower the speaker impedance, the higher the output power!!!!
Please make sure that the power of the adapted power supply is greater than the actual working power of the amplifier!!!!
