The Scuderia Audio 599/612 Rear Subwoofer Upgrade fits the following Ferrari models including but not limited to, Ferrari 599 GTB, 612 Scaglietti

Scuderia Audio presents an upgrade path for the large subwoofer in the center of the rear package try for Bose equipped 599s and 612s.
Replace your existing Bose speaker with a monster 9 inch German made subwoofer (6 1/2 pounds!).
Includes a stainless steel, laser cut, tig welded adapter plate that allows you to bolt the new subwoofer to your rear package tray with no modifications of any kind. Better bass, guaranteed.

NOTE: This kit will NOT fit a non Bose equipped 599 or 612 unless you physically cut a 10 inch hole in the middle of your rear package tray (as Ferrari does with the Bose cars) and buy a Bose style rear package tray cover.
