Not sure if you plan on leveraging the factory amp, or if you are installing all new components with your head unit. There is an item available that will allow you to use the factory components. The problem lies with the fact that Porsche uses an optical wiring system. You either need to bypass that system completely, or purchase a bridge to hook into it.
