13. Reminder: There will be enough output power only when the audio input is enough and the power supply/current is enough. the higher the power supply voltage, the higher the relative power, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger the horn ohms, the smaller the relative sound power
