Tips: 1. When the audio input is sufficient and the power supply voltage/current is sufficient, there will be enough output power; 2. The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power; 3. Please ensure The power of the adapted power supply is greater than the actual working power of the power amplifier!!!
