Why does my stereo keep running when the car is off?
“Memory”, as you correctly guess, provides a constant power to the stereo head that retains presets etc. If you get 0v when the car is off, this is probably incorrectly hooked up to the ACC (Accessory power) instead of constant 12v. Red Wire labeled “ACC” should only have power when ignition is turned to ACC or car is running.
Can you listen to the radio with the car off?
However, if you really want to be able to listen to it with the car off then you would have to do something like what you have done, and splice the always on 12v to both connections on the stereo. The only thing I might change is to make sure that always on connection has a fuse.

How does the radio stay on when exiting a car?
