go to the interactive website they put up. then click on boxster details. Once the hugh flash file loads you get this cool walk around of the car... including details on the stereo. Not only are there extra speakers in the doors now theres a hugh sub-woofer behind the seats. The special stereo package has something like 13 speakers. for the porsche/audiophile thats going to be bliss.
