An audio system for a vehicle, such as a personal watercraft, having a vehicle body dimensioned for receiving a side-view mirror, includes a speaker pod that includes a housing dimensioned for supporting a speaker operable to produce sound, and a mounting member for mounting the speaker pod to the vehicle body in place of the side-view mirror. A portion of the housing is shaped similarly to a corresponding portion of the side-view mirror. A method of installing an audio system on a vehicle having a vehicle body dimensioned for receiving a side-view mirror involves: (a) determining that the side-view mirror is removed from the vehicle body; and (b) mounting a speaker pod of the audio system, along a mounting member of the speaker pod, to the vehicle body in place of the side-view mirror such that a housing of the speaker pod supports a speaker operable to produce sound.
