Actually some of the newer aftermarket stereos have internal switch
controls that minimize power draw, but can sometimes allow excessive
currents. The CSS stereo I have when switched off, and still connected
to constant +12V, draws about 35mA. I think most of that is the display
backlight, which turns off when I remove power completely. The CSS
stereo does keep memory settings for quite a while with power off, about
2 weeks or so.
