I have a car stereo head unit that I'd like to repurpose as a radio for my garage. Given that, I'm looking for some kind of power adapter / transformer that I can plug into a wall outlet and splice into the stereo harness. Presumably this would need to convert from 120VAC to 12VDC, but I'm not sure what I'd need as far as amperage goes. If it's relevant, the stereo was on a 10 amp fuse when it was in the car.
I've seen people use computer power supply units, the big 350 W guys, but that seems like major overkill here especially since I'm only looking for the 12v and wouldn't need the other wires from a PSU like the 3.3v and 5v lines.
