Let’s take into account all of the possible causes.
Check the wiring.
After installing your new audio system, if the problem persists, you’re probably dealing with a wiring problem. Car stereos employ either a single ground wire or two power cables. When the engine is running or the ignition is in the auxiliary mode, one wire is always hot and the other is not. If the primary power line for your head unit is connected to a persistently hot power supply, the radio will never turn off. Voltage meters and test lights can be used to look for this problem.
Wiring a radio such that it receives electricity only when the ignition is in the auxiliary or drive mode is necessary if both of the radio’s input wires are continually hot.
Double-check your ignition.
Auxiliary power may be available even if the key is removed if the ignition switch malfunctions. If you discovered that the engine has warmed both of your electrical wires in step one, this could be a problem. No power supply could be found, even when the ignition was in the auxiliary or drive position.
When the ignition is off, be sure to look to see if any of the accessories have electricity. Adjust the cylinder or replace the ignition switch if you have electricity.
Check the cylinder and key.

Unlike the prior problem, this time it’s the manual ignition cylinder that’s at fault, rather than the electrical switch.
If your key or ignition cylinder is very worn, you can remove it while the switch is still in the auxiliary or on position. Make sure the ignition switch is switched off when you remove the key in order to fix this problem. You should be able to turn off the radio using this way. It is best to replace the worn-out cylinder in order to fix the problem permanently.
Check the radio settings.
Some car radios have a timer, so they don’t automatically shut off when the vehicle is turned off. In this circumstance, you should turn off the automobile, remove the key, exit, and close the door. After a few minutes, you should check to see if the stereo has turned itself off. It’s common for the radio in your car to shut off after a few minutes of continuous playback. If the dome lights aren’t turning off when the doors are closed, try closing the vehicle and opening it again to see if that helps.
If the dome lights won’t turn off, you may have a bad car door switch. In addition, a professional is often needed to deal with this type of problem.
Is It Bad to Have the Radio on When the Car Is Off?
That’s correct. The consequences of a car audio that won’t shut off can be disastrous. There isn’t much power used by car radios but it’s enough to deplete your battery overnight if your battery is nearing the end of its life span.
As a result, it is imperative that you carefully secure your radio and all other accessories, even while the engine and ignition are turned off.
Does Leaving the Radio on Drain Car Battery?
Definitely. Leaving the radio on while the car is parked might drain the battery. While radios and stereos use a lot of power, they are relatively low-energy devices. This means that battery drain is mostly certainly due to an unrelated issue. Some of these include fans, heaters, and lighting
You should also keep track of how much power your stereo uses while it is turned off. It all relies on your car’s audio system. A subwoofer that consumes a lot of power, for example, will use up a lot of power in a short time. Radios with large displays may also consume more power. The battery will run out faster if you fiddle with the switches a lot.

A problem with the door’s wiring and electricity or the radio itself may be to blame if your radio does not switch off when a door opens. Your aftermarket head unit may have a wiring fault if you’ve experienced problems since installation of the unit. Car radios use a single ground wire and two input wires. During normal operation, one energy wire is always hot, while the other receives electricity only when the ignition switch is in the auxiliary position or when the automobile is running.
To test if your radio is set to stay on for a predetermined amount of time, check the settings. For example, some car radios have a timer that prevents them from shutting down immediately. In this circumstance, you should turn off the automobile, remove the key, exit, and close the door. You should check to see if the radio has turned itself off after a few minutes as soon as you turn it on. As a side note, the door’s wiring must also be examined. The door’s wiring may be faulty if all the accessories stay open when the door is closed. Asking an expert for guidance is the greatest option if you don’t understand what you’re doing.
