Review on 🔊 Huazhu DC12V-24V 2.1 Channel TPA3116 Subwoofer Amplifier Board High Power Bluetooth Audio Amplifier Board 50W+50W+100W (Bluetooth Amp) by Laura Adams

Please see my video for details. There may be strange RF interference from Bluetooth transmission. I've found that connecting a short wire to the heatsink somehow eliminates the interference. So the problem is solved. For a sub $30 Class D amp that puts out 50 watts per channel and another 100 watts to the subwoofer, with finely tuned crossovers and tone, this is a solid amp. My second to use in these custom speaker builds. Excellent quality and very clean sound of food.
