I forgot I needed more power, tried to make portable stereo. At 200 watts 12v that makes 16.667 amp requirement. i was planning to use a 20,000 mah battery which only provides around 3 amps. I should have made a bit of calculation then. I thought the unit was not working, until I figured it out. Will try to find larger power supply. Still have not heard board in action. No idea whether it has good sound or not.
