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

Interesting Sign. I chose it based on my experience with the Aoshike 120w x 2 amplifier board and was a bit overwhelmed at first. Possibly because I compared this board (50w x 2, 100w x 1) to another 120w x 2 board. I still feel like I need more performance for my tastes. I like the 2.1 setup better than the pure stereo board. Maybe I need to think about a bigger and more powerful 2.1 amp amp. One interesting thing I found was that this board has a built in MP3 player! All I had to do was add a USB port to the board, plug in a USB stick with MP3 music (I haven't tried other formats), press the volume knob to switch between inputs - Bluetooth, Line and now USB. I just wanted to be able to charge my phone while playing music but what a surprise. I'll keep digging to see if there are other things about this board that aren't advertised.
