Only 30 watts, not 30 watts per channel.

The TDA7377 pro I tested delivered less than 15 watts per channel at a maximum voltage of 18V into 4.7 ohms, the volume pot reaches its maximum voltage and then decreases again as you raise it further. I haven't heard anything with it, so I can't comment on the sound quality. Package arrived on time and properly packaged for delivery, there was no flux residue on the board, I noticed solder drips on the exit trace. The thermal protection is effective.

Pros

Safe Protection: The stereo amplifier board is equipped with input reverse protection, short circuit protection, overcurrent protection and overtemperature protection, which can perfectly protect your device and extend its service life.

Cons
