XH-M139 TPA3116D2 2x50W + 100W Subwoofer 2.1 Digital Power Amplifier

Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient, there will be sufficient output power. 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's ohms, the smaller the relative sound power, please pay attention!
