C70 [MK2] (2006-2013)
The second generation C70 model debuted in 2005 sharing the Volvo S40 platform. They were built by Pininfarina Sverige AB — a joint venture between Pininfarina and Volvo.
The Volvo C70 from 2005-2013 had 3 different sound systems:
Performance Sound
This was fitted as the standard sound system for these models and is the most common. Although it had a couple of variations during its lifespan, it typically consisted of a 6 or 8 speaker set up without an amplifier.
High Performance Sound
When the powering up it will show 'HIGH PERFORMANCE SOUND' on the radio display. This was fitted both as an optional audio upgrade, or as standard on higher spec Volvos. It incorporates a separate amplifier.
Dynaudio or Dolby Pro Logic II
When the powering up it will show ‘PREMIUM SOUND' on the radio display. These sound systems were fitted as optional upgrades and incorporate a separate amplifier and uprated factory speakers. Logos on the speakers will help identify whether a Dynaudio or Dolby system.
