Methods and systems for controlling audio output of an exterior vehicle audio system

A vehicle comprising an exterior audio assembly, a vehicle audio system, and a controller area network (CAN) bus, wherein the vehicle audio system includes an audio control computer device, and wherein said audio control computer device is configured to:

• store, in a memory device, at least one limited volume level and a corresponding speed range;
• receive a speed-related parameter indicative of an actual speed of the vehicle from a vehicle control system;
• determine if the actual speed of the vehicle is within the stored speed range based on the speed-related parameter;
• and
• permit operation of the exterior audio assembly at the at least one limited volume level when the actual speed of the vehicle is within the speed range.

A computer-based method for controlling a volume level for a vehicle audio system associated with a vehicle and in communication with an exterior audio assembly, the vehicle audio system including an audio control computer device, the audio control computer device in communication with a memory device, the method comprising:

• storing, in the memory device, at least one limited volume level and a corresponding speed range;
• receiving a speed-related parameter indicative of an actual speed of the vehicle from a vehicle control system;
• determining if the actual speed of the vehicle is within the stored speed range based on the speed-related parameter;
• and
• permitting operation of the exterior audio assembly at the at least one limited volume level when the actual speed of the vehicle is within the speed range.
