I'm slowly integrating spare car audio equipment into the stereo in my garage, using a car battery and charger as my source. I'd like to build a proper power supply with sufficient current available to power a basic system with a speaker and sub amp (say 25A to 50A). I would also use it to test equipment, etc - anything requiring 12 volts. There are a lot of schematics available online, but I don't know enough about power supplies to know which is right for me. Does anyone know of a good buildable supply appropriate for this application?
