Kind reminder:
Only when the audio input is sufficient and the power supply voltage/current is sufficient, can there be sufficient output power. Higher power supply voltage will result in higher relative power, and speakers with different impedances will have different output power. When the voltage and current are sufficient, the larger the number of ohms of the speaker, the smaller the relative sound power. Please pay attention!
Power supply 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/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,
