Most likely you can just ground everything in the same place. Depends on what your circuit is though. Post a schematic if you want an exact answer.I'll try it just one question, if theres only one output where will I put my load's ground?
You missed nothing..If you have enough power to run the amplifier, you have enough power to charge the battery. What am I missing?
I suspect I do and it's not possible. Amplifiers do not manufacturer energy, they "amplify" a signal by using the energy from a DC power source (such as a battery) to convert a low level signal to a higher level signal. They can not take a 10mV lower power signal and make it into a high power 110V signal without power being added from the power supply.I'm just trying to amplify 10 millivolts to make it usable. So basically If it's ac it has to be 110 volts but if I do dc it has to be enough to charge a phone. Do you know what I mean?
