Review on uxcell Super Mini PAM8403 2*3W D Class Digital 🔊 Amplifier Board - Power Your Audio with USB - 2PCS by Dustin Woodrow

Be careful when soldering. I toasted 2 before I got the hang of it (I'm new to soldering) but when I did these things were amazing. They don't work well with 2 x 4 ohm speakers above half volume, but a single 4 ohm or 2 x 8 ohm speaker will sound great with them. Also works better on 5V. But at 5v with 2 x 8 ohm speakers you won't believe this brand sized amp is powering your stereo. The stereo I made sounds just as good and loud at full volume as my car stereo does at 60%. And my car has 2 6x9 and one 8" subwoofer with a 200 watt amp.
