ARUIMEI 100W 2.0 Channel Digital Stereo Class D Audio Power Amplifier Board DIY 50W + 50WAmplificador Sound Board DC 8-26V 4A

This is the 2nd one that I've ordered. Finally got around to testing the first one. Both from this vendor. The first one had no adhesive on the heatsink. I have thermal tape, so I took care of that. The second one came with adhesive on the heatsink. Not a big deal for me. - The sound from this tiny board is just great! Testing at 12V now. When used with a JQ-D098BT MP3 player, it has a slight typical shared power supply noise. With a YMX-02BT or a ZTV-M01BT there is no shared power noise. Perfect match. I will gladly get more of these for when I need a tiny package, since it even has the filter section. Proper choke and cap values for 4ohms too! Thanks!

Arrived very quickly. Everything is fine ★ ★ ★ ★ ★ . I can recommend the product and the seller. This small amplifier makes a nice thump and has a good sound. I tried it in a test setup with 2x 50W (100W) speakers, preamped a Bluetooth, USB/TF, and radio module, and played MP3 files from a USB stick. Unfortunately, the heatsink was not glued on, and you have to get the adhesive yourself.

Very good products here, the set I will use to listen to my music has 4 channels of 50 watts (maybe not real but I assure you they don't disappoint) in each cabinet (MDF gift bags) powered by 18 watts with a laptop power supply. Happy with these manufacturers, shipping, and my new hobby.
