Amplifier chip: domestic amplifier IC
Applicable power supply: DC 12~19V/5A or above (the higher the voltage, the greater the output power)
Applicable speakers: 20~100W, 4~8 ohms
Output power: left and right channels
Protection mechanism: overvoltage, undervoltage, overheating, AC/DC detection, short circuit protection

Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient, there will be enough output power!
The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power!
Please make sure that the power of the adapter power is greater than the actual working power of the amplifier!
