How to amplify car speakers without stereo?

처리 내용

What you need is a simple switch. Here's an example of one that you can order from DigiKey. Your radio will use two wires for powering itself, the ground ( GND ) and V+ . The ground wire should be grounded, that is connected to negative (-) terminal of the battery. The V+ wire should be connected to one connector of the switch. Battery positive terminal (+) should be connected to the other connector of the switch. Switch will simply short-circuit positive battery terminal to the radio when turned on. This is the simplest solution that I can think of. Well, there is a simpler one, using just bare wires and connecting them when needed, but I guess that would be somewhat weird solution.
