An AC-DC power supply or adapter is an electrical device that obtains electricity from a grid-based power supply and converts it into a different current, frequency, and voltage. AC-DC power supplies are necessary to provide the right power that an electrical component needs.
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.
What should I do if my car stereo is not working?
Pull out the new car stereo to gain access to the wires again. Look for a blue wire on the aftermarket head unit and ensure that it’s connected to a corresponding wire within your vehicle’s wire harness. The Blue or Blue/White wire on your aftermarket head unit is what powers a powered antenna.
Is it possible to leave the radio on and drain the battery?
I can’t say exactly, but to directly answer the question: yes it’s entirely possible for you to leave your radio on and drain the battery. 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.
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.

Why is my car radio not working when the engine is on?
Do you have any problems with other circuits in the car that are fed off the accessories power e.g. cigarette lighter, power windows etc? If it only happens to the radio with the engine on and more when you are driving it sounds like there is a loose connection or dry soldered joint in the power supply for the radio or in the radio.
What kind of power does a car stereo have?
A car stereo will always have 3 different power wires going to the deck section. Black (usually ground) Red (usually battery) and Yellow (usually constant power). Make sure that your car radio has these 3 wires hooked up correctly. This should allow the radio unit to power on and function normally.
