Leaving your radio on so that you can hear it working with no key in the ignition is only possible on some cars. It’s useful to be able to do this sometimes, but there is indeed a risk you will accidentally leave it on for a long period and eventually flatten the battery so you can’t start it.

Do you turn off the radio when you turn on the car?
However, if your radio is wired to continue to play when the keys are removed then do switch it off to prevent excessive battery drain. It depends. Some (most?) cars shut off the accessories automatically in “start” mode, however you still have a brief drain even then as you flip past “on” to “start”. Does it matter?
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.
What to do if your Mercedes Benz Radio is not working?
For you to do that, you will need to remove the fuses for the CD Changer, COMAND/ NAV / DVD Player / Radio, Audio Gateway AGW, and the Voice Unit if it is equipped with one, for at least 10 minutes. Doing a soft reset for these systems will force the head unit to rest. This normally restores the systems to working order.
What should I do if my Radio is not powered on?
If the line is not fused already, or there is no fuse in the panel I would suggest getting a cheap inline fuse-holder to splice into the wire. Always fuse hot connections as close as possible to the battery or other DC source.
