Warm hint hint:
There will be enough output power only when the audio input is sufficient and the power supply voltage/current is sufficient. Higher power supply voltage will be relatively more powerful, and speakers with different impedance will have different output power. With sufficient voltage and current, the higher the speaker ohms, the lower the relative sound power, please note!
