ERH India TDA 7297 Amplifier Board Kit Single IC 7297 Based Amplifier Board

Amazing quality at this price, good bass and treble, I tested on quality 4 ohm with tweeter, great output, one thing to make note of, audio input black color wire is actually audio input, and yellow is ground instead, simple tracing, company should ensure this in their production assembly, also I used good supply no noise, some basic supply may be noisy

failed amplifier circuit board, not successful pcb , audio sound not giving results properly.

It is goodBass is superBig soundAnd I connect 50 watt speaker in this board only one channelThank you Amazon
