-1602T Bluetooth Audio Power Amplifier Module TDA7498E 160WX2 Protection mechanism,Anti-reverse connection, undervoltage, overheating, overcurrent, short circuit protection The function of the fan,Lower the overall temperature of the module so that it does not get too hot. The higher the power supply voltage, the greater the output power, the smaller the horn impedance, and the greater the output power! When the audio signal input is large enough and the power supply voltage / current is large enough, there be enough output power!
