Here we have a good used oem bose stereo amplifier removed from a 2005 Porsche Cayenne Turbo which sustained some front damage with only 63,000 kms!!! (39,000 miles). These parts should fit all 03-06 Cayenne with bose sound system only. We are also parting out the rest of the car so If theres anything else in particular you need otherwise please send an email so I can list it on ebay for you. Removed from Vin# WP1AC29P55LA91908.
