Common speaker matching reference scheme and power supply selection: In theory, choosing a higher voltage corresponds to higher power and lower distortion at lower voltages. Here's one thing to mention, Under normal circumstances, the power output of 24V is four times, not twice, that of 12V. It is recommended to use a power supply of 8A or above for 12V, which can make a sound power speaker within 2 * 15+30. It is recommended to use a power supply of 10A or above for 16.8V, which can be used to make a speaker with a sound power of 2 * 35+70 watts or less. It is recommended to use a power supply of 12A or above for 21V, which can make a speaker with a sound power of 2 * 50+100 watts or less.Note: The X channel supports speakers with an impedance of 2 ohms or more. Use voltage not exceeding 24V and try to use battery power as much as possible.Product List: 1X power amplifier board
