Note: When the audio signal input is enough and the power supply voltage/current is enough, there will be enough output power!
The higher the power supply voltage is, the greater the output power is.
The smaller the horn impedance is, the greater the output power is. that the power of the adaptive power supply is the actual working power of the power amplifier Product name: 2.0 channel Bluetooth audio amplifier module
