The STK412-530 is a high-performance, two-channel Class H audio power amplifier hybrid IC originally developed by Sanyo (now part of ON Semiconductor). It is designed to provide high-efficiency audio amplification for home theater systems, car audio, and professional equipment Core Technical Features The module utilizes a shift power supply
Output Power: Typically rated around 150W per channel into an 8-ohm load.
Total Harmonic Distortion (THD): 0.8% to 1.0% at rated power (20Hz to 20kHz). stk412530 datasheet

Final advice from the datasheet's fine print: Always use a bulb current limiter (DBT) when testing these modules. A shorted STK will take out your power supply transistors, rectifier diodes, and speakers faster than you can hit the power switch. The STK412-530 is a high-performance, two-channel Class H

The datasheet provides a specific pin configuration (25-pin SIP). Unlike discrete transistor amps, misreading pin 1 on an STK module means instant destruction.
