These amplifier modules are great for small-scale projects but keep expectations realistic. At 3W per channel, they top out at 6W total… not nearly enough to drive a 50W speaker properly. For the best results, stick to 4-ohm speakers rated at 3W; anything between 4-8 ohms at 10W will still sound decent.A key tip: use coaxial cables for both the DC power and audio input; this avoids the nasty RF interference that will ruin your sound. Shielded cables are a must for the inputs, while regular wiring works fine for the outputs. When set up correctly, these amps deliver clear, impressive audio for their size and quite perfect for DIY speaker setups.

These little PAM8403 modules are really cool. They are quite tiny, but they pack a good punch. I tested this using a 5V battery and the Aux signal from my phone going into a 50W speaker, and was very impressed at how good these little boards sounded, and how loud they were. I was expecting them to be pretty anemic, but the volume was actually quite good for being only 3W. I did get a bit of clicking and popping at maximum volume, but I think that was more due to some loose DuPont connectors in my setup. 5 of these for under $10 (at the time of this review) is a great deal. Note that these use 5VDC power, nothing higher. These little board would be great to amplify some audio from a microcontroller like an Arduino, if you’re into those kinds of projects (I certainly am). Easy 5 stars. I’m really starting to like the Jessinie company – all their products seem to be quite good, and this is no exception.
