The owner if this 350Z was decidedly underwhelmed when he auditioned the factory Bose audio upgrade, so contacted Prestige Audio before he took delivery to arrange something a little more in suiting with the car. A pair of Diamond Audio D1 10" subwoofers powered by a 500w DLS monoblock amplifier perform the bass duties from their vinyl and alcantara trimmed enclosure underneath the rear Z brace, and a matching DLS two channel amplifier powers Diamond Audio Hex front speakers in heavily reinforced front door locations. An Alpine touchscreen DVD head unit replaces the rather flacid Nissan head unit and contains an interal high speed iPod interface.
