Warm Reminder:

Sufficient output power can only be achieved when there is adequate audio input and sufficient power supply voltage/current. A relatively higher power supply voltage will result in greater power. Speakers with different impedances will have different output powers. When the voltage and current are sufficient, the higher the ohm value of the speaker, the relatively smaller the sound power will be. Please note!
