A class D power amplifier modules with RMS output of 2x150W power from 12V car battery. The power amplifier module is powered by 300W DC/DC converter +/- 30V with PWM controller board. Complete working power amplifier module for driving 4~8 ohms speakers. Planning to add remote control for volume/tone control with LCD display with IR remote control.
