Product name: 2.1 channel audio amplifier board Power supply voltage: DC12-24V Output power: 50w*2+100w heavy bass*1 Output load: 4-8Ω Frequency response range: 14-100KHZ Number of channels: 3 (left channel + right channel + subwoofer) Switching frequency: 1.2MHZ Tips: Only when the audio input is sufficient and the power supply voltage/current is sufficient, will there 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!
