Question by : How to add a switch between a car radio and a car battery?
I am building a portable audio system, which is powered up by a battery. The radio I’m using goes to standby when I turn if off, so it’s still using power. Since its a portable system, I would like to somehow turn the radio completely off so it doesn’t use power while I’m not using it. Can I add a switch that turns the radio completely off?? Or will the radio in standby won’t be using almost no battery at all.

You can certainly add a switch. Add it between the positive lead of the battery and the radio.
