    Hey guys I am a real noob at circuit designing. Here is an amplifier circuit I put together for a center channel subwoofer of a 2.1-channel USB-powered speaker system that I am planning to build. I basically made this circuit by binge-watching YouTube videos and following the IC's datasheet. Now...
