I'm looking for a schematic for a single transister NPN audio amp. It is will be used to amplify the beeping signal from a radar detector. Input signal will be coming from a headphone jack. I would like it to power off of a 12vdc supply, so that I can hardwire it into the vehicle, but if it's simpler to use a smaller power source, batteries are fine.
This is not for music, so I don't care about frequencies/clarity, I just need to amplify the beeping alerts from the RD. Looking for the simplest possible.
I tried building this below on a breadboard, but it didn't work. Of course it was probably a builder error
