This document contains the circuit diagram and design details for a 900-watt, 2-ohm stereo amplifier. The amplifier uses numerous transistors, resistors, capacitors, and other components arranged in a typical amplifier circuit configuration to provide amplification for left and right audio channels. It was designed by Erik Prianto Tindaon and is intended to drive a 2-ohm speaker load with a maximum power of 900 watts total across both channels.
