2PCS TPA3116D2 High Power Hifi Digital 2.1 Subwoofer Amplifier Board 10-25V Finished Board
The power interface is embedded with a reverse protection unit, and the reverse connection will not burn.
The output power depends on the power supply voltage and speaker impedance. For high-power applications, the recommended voltage is 24V and the current is greater than 5A. Try to use a 4 ohm speaker, which is good for high-power.
Low-noise judgment method: the input terminal is short-circuited, and the speaker is connected for trial listening. Normally, it should only be a faint noise. If the noise is too large, it is abnormal. If the noise of the computer or mobile phone increases, it means that the noise comes from the signal source.
