PS: In the audio input is enough, the supply voltage/current is enough, there will beenough output power! The higher the supply voltage, the greater the output pow-er.The smaller the impedance of the speaker, the greater the output power! Please make sure that the power of the adaptive power supply is greater than the actual working power of the power amplifier!!
