PS: In the audio input is enough, the supply voltage/current is enough, there will be enough output power! The higher the supply voltage, the greater the output power.The smaller the impedance of the speaker, the greater the output power! Please ensure that the power of the adaptor is greater than the actual working power of the amplifer!
