Only when the audio input is sufficient and the power supply / current is sufficient can there be sufficient output power. The higher the power supply voltage, the greater the relative power, and the speakers with different impedance will have different output power. When the voltage and current are sufficient, the greater the number of ohms of the horn, the smaller the relative sound power. Please pay attention! 2.
