The ZK-MT21S amplifier performs well overall—the sound quality is solid and installation was easy. It’s just a bit bulkier than I expected, but it still fits in my setup without issues.

The ZK amplifier board functions nicely—Bluetooth pairs quickly and sound is good. The instruction manual is a bit brief, but I managed to figure everything out with a little trial.

This CA-AS21 amplifier board is fantastic for my DIY speaker setup! The sound output is clear and powerful, and it was really easy to install. Works great with 12-24V power—loving it!
