PREMIUM SOUND. DEBAUCHERY MEASURED IN DECIBELS.
With a choice of two audio levels—High Performance and Dynaudio Premium Sound—each configured to the cabin's ambient acoustics—the Volvo C30 has a sound system
that makes the most of your music. The world-class components are mounted in the dashboard separately from the controls on the floating center stack and the control
buttons on the steering wheel.
