🔊 DGZZI 2PCS Super Mini PAM8403 DC 5V 2 Channel USB Digital Audio Amplifier Board Module 2 3W Volume Control with Potentiometer Switch Review

After trying this amplifier, I was incredibly disappointed. The sound quality was poor and the device had static noise. While it was affordable, you definitely get what you pay for.

I connected the speaker and input connections to the board with 20 AWG wire. I then connected the 3.7v 18650 lithium battery and case. Plugged in speakers and laptop output. Turned it on and everything worked. I cut the wires to the battery compartment and added a 2.1x5.5 male and female connector. I turned on the amp and all I heard was a continuous click. I removed the plug and connector, reconnected the wires. Same, click when it's on. That's the amp, not my connections. Today I connected…

Great little amp, great sound reproduction. Not very loud but more than enough volume to get the job done, it's definitely worth the money but don't expect it to blow windows and rumble on walls. Easily accessible solder joints, overall I'm very impressed. My only criticism, if I had to give one, is the inability to merge two channels into one to get maximum performance in just one channel. I've tried doing a few different things to achieve this and failed, but couldn't get the result I wanted.
