Review on High-Quality 2.1 Channels Bluetooth 5.0 Subwoofer Class D TPA3116D2 Amplifier/Receiver Board - 50W+50W+100W, Adjustable Bass Frequency, DC 12-24V by Erika Martin

Revainrating 5 out of 5

OK for music for receiver and amplifier

I didn't buy it for music. I bought it to play sound at 10kHz. Why? Do not ask! Anyway, if you want to play single or stereo sounds, I wouldn't recommend this device. It goes into the cutoff with almost no turning of the volume control. This means the security features are likely to work, and that might be fine for plug-in music or Bluetooth, both of which work.

Pros
  • Upgraded function, with adjustable subwoofer frequency, it is convenient to adjust the depth and power of bass output.
Cons
  • Weak Kit
