Review on πŸ”Š High Power Dual Channel Digital Amplifier Board, TPA3116D2 Audio Stereo AMP Subwoofer Power Amplifier Board 2x50W 5V 12V 24V, Ideal for Store Solicitation, Home Theater, Square DIY Speakers by Allie Diaz

Revainrating 4 out of 5

Surprised it worked for me

Need sound in my house with a screen. I installed some speakers, got a plastic case from the dollar store, put this little amp in it and plugged it in. The amplifier connects to a standard mini plug. I'm using a small portable MP3 FM radio speaker as the input. The output tone is perfect for my room. Loud enough for the neighbors to hear.

Pros
  • The digital amplifier board runs on a wide operating voltage of 4.5-26V DC (24V recommended) with reverse polarity protection and is highly recommended for 4-8 ohm speakers;
Cons
  • Cable is shorter than other picks
