XH-M139 2.1 Digital Power Amplifier Board TPA3116D2 2X50W+100W

Only when the audio input is sufficient and the power supply voltage/current is sufficient will there be enough output power. If the power supply voltage is higher, the relative power will be higher.
Speakers with different impedances will have different output powers.
In the case of sufficient voltage and current, the larger the ohms of the speaker, the smaller the relative sound power, please pay attention!

voltage:
12V ------- 8 ohm speakers/12W (left channel) + 12W (right channel) 4 ohm speakers/20 (left channel) + 20W (left channel),
15V ------- 8 ohms/18+18W, 4 ohms/greater than 30+30W,
19V ------- 8 ohms/32+32W, 4 ohms/greater than 45+45W,
24V ------- 8 ohms/38+38W, 4 ohms/greater than 55+55W,
