• TIP: adequate output power is required when the audio input is sufficient and the power supply voltage/current is sufficient, the relative power will be higher. Different impedance of the speaker will have different output power.In the case of sufficient voltage and current, the larger the impedance of speaker, the smaller the relative sound power, please pay attention!
