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.

This ZK-MT21S amplifier board works fantastic! The bass is rich and powerful, and setting it up with 12V DC adapter was straightforward. The audio output is clear even at high volumes, totally worth the purchase.
