Note: To achieve the maximum output power, use a 19V–24V DC regulated power supply with sufficient current capacity (typically 5A–8A) and connect 4Ω or 8Ω speakers rated appropriately. Actual continuous (RMS) output power depends on the power supply voltage, speaker impedance, and the amplifier IC used on the module. Ensure adequate ventilation around the heat sink during high-power operation.
