The Acura/Bose® Music System of the 3.5RL with Premium Package is the most impressive ever designed for an Acura automobile. Developed and tuned by Bose Corporation specially for the RL, the music system is acoustically optimized to provide clear, authentic sound in any seating position of the interior, and to automatically compensate the balance of bass, treble and midrange for any volume level.

Eight speakers are used: two 2.5-inch front tweeters, mounted high in the front doors, two 6.5-inch single-cone full-range speakers in the lower front door panels, two 5.25-inch full-range speakers, mounted in the rear door panels and two 6 x 9-inch low-frequency drivers in the rear package shelf.

From the easily accessible, dash-mounted control unit, audio output is sent to the auxiliary power amplifier unit located in the trunk. Separate amplifiers are provided inside the unit for each of the six individual front speakers. Each tweeter has a l2.5-watt amp, each of the four full-range speakers has its own 25-watt amp, and the two rear speakers, which act in concert as subwoofers, share a 100-watt amplifier. Total music system power: 225 watts.

The Acura/Bose® Music System also includes a six-disc CD changer, located in the trunk.

The standard music system of the 3.5RL is an AM/FM stereo/cassette system, with an optional CD changer; it also uses an 8-speaker configuration. The front tweeters are 1.5 inches in diameter, versus 2.5 inches in the Acura/Bose system; other speaker sizes and locations are the same in both systems. The standard system maximum output is 105 watts.
