What is svc in a car?

SVC stands for Speed Sensitive Volume Control, a feature commonly found in car audio systems. SVC automatically adjusts the volume of the audio system based on the vehicle's speed, increasing the volume as the car goes faster to compensate for road and engine noise. This ensures that the driver can still hear music or other audio clearly, even at higher speeds. SVC can help improve the overall listening experience in a car and reduce the need for manual volume adjustments while driving. Many modern cars come equipped with this feature as a standard or optional feature.
