A discreet, stealth install, for a discreet and stealthy car! Audiophile Diamond Audio D7 amplifiers under the boot floor, with a custom subwoofer box for 2 x 6" subs takes up very little luggage space (the system was designed to allow the optional Ferrari luggage to still be used). Diamond Audio Hex front speakers in the factory locations and an Alpine touchscreen DVD navigation system complete the lineup.
