How to power speakers with batteries without an inverter?
I would like to know if there is a way of by-passing the built in inverter and connecting the battery directly to the speaker without causing harm?
What I thought was using a multimeter, measuring the voltage and the amper output of the built-in adapter and buying a battery with the same numbers and connecting it directly there. What are the risks in there? because I don´t want to burn my speaker.
