Tips:

Sufficient output power will only be available if the audio input is sufficient and the supply voltage/current is sufficient.

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 power supply is greater than the actual working power of the amplifier!
