Description
2*50W+100W 2.1 Channel Digital Power Amplifier Board DC12V-24V TPA3116d2 Subwoofer Digital Power Amplifier
Product Description
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! Voltage: 12V ------- 8 ohm speaker/12W (left channel) + 12W (right channel) 4 ohm speaker/20 (left channel) + 20W (left channel), 15V ------- 8 ohms/18 + 18W, 4 ohms/more than 30 + 30W, 19V ------- 8 ohms/32 + 32W, 4 ohms/more than 45 + 45W, 24V ------- 8 ohms/38 + 38W, 4 ohms/more than 55 + 55W,
