Does playing music while parked consume battery power?

[McLeo]

Playing music while parked does consume battery power. Here are the reasons: 1. When the car is turned off but you're still listening to music in the vehicle, it solely relies on the car battery's power. Normally, the battery is only used momentarily during engine startup. 2. After the vehicle is fully started, the engine drives the alternator to work, thereby supplying power to both the car battery and all electrical components. Therefore, if you must listen to music, it's best to keep the engine running. Never use electrical appliances in the car when the engine is off. 3. If the car has additional high-power audio equipment installed, playing music during idling or before starting the engine will place a significant burden on the battery, shortening its service life.
