Tip:To have enough audio input and enough power supply voltage/current to have enough output power and higher supply voltage
The relative power will be larger, and the speakers with different impedance will have different output power. In the case of sufficient voltage and current, the higher the speaker ohm
The larger 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/20W+ 20W
15 ----- 8 ohms/18 + 18W, 4 ohms/greater than 30 + 30W
19V ---- 8 ohms/32 + 32W, 4 ohms/greater than 45 + 45W
24V ---- 8Ω/38 + 38W, 4Ω/greater than 50 + 50W
