Our customer wanted iPhone and ipod control and a full audio and speaker upgrade for his Carrera 4s. We removed the original audio system and replaced it with an Alpine bluetooth and iPod (iPhone) radio system. The Alpine system gives the Porsche full hands free control for the iPhone and controls for the iPod.
We also gave this Porsche Carrera 4s a hidden 4 x 100W amp and upgraded all 6 speakers whilst retaining the Carrera's factory look.
Of course we tested the system thoroughly and setup the sound for  the best EQ.
Porsche audio upgrade done right first time!
Images of this Porsche Carrera audio upgrade  are available in our work examples section.
