A supercar deserves a super sound system. Specially developed for the new Nissan GT-R by BOSE and Nissan engineers, the sound system is matched to the exact acoustic requirements of the cabin, including shapes and materials. The 11-speaker system includes tweeters, squawkers and woofers. There are also two woofers in the rear center armrest facing forward. The innovative layout uses the trunk for speaker enclosure. This rear center woofers and door speakers mounted in rigid aluminum diecast panels, which improves sound quality especially tight bass sound.
The built-in DC-DC converter enables voltage to be amplified from the ordinary 12 volts to 52 V, realizing a higher output. The new PWM amplifier (switching amplifier) balances high output, high efficiency, and light weight. Speaker layout
