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 4A or above for 12V, which can be used to make a sound power speaker within 2 * 15W.It is recommended to use a power supply of 5A or higher for 16.8V, which can be used to make a speaker with a sound power of 2 * 35W or less.It is recommended to use a power supply of 10A or above for 21V, which can make a speaker with a sound power of 2 * 60W or lessIt is recommended to use a power supply of 10A or above for 24V, which can make a speaker with a sound power of 2 * 70W or lessIt is recommended to use a power supply of 10A or above for 32V, which can make a speaker with a sound power of 2 * 100W or lessNote: Speakers with an impedance of 2 ohms or more are supported below 24V, and the power is doubled. Please use speakers with an impedance greater than 4 ohms for 24V and above.
