Cadillac teamed with one of the biggest names in sound — Bose® — to create an electrifying audio experience. Featuring crystal clear sound, the available Bose® premium sound system includes Centerpoint® surround sound, a digital amplifier and AudioPilot® 2 noise compensation technology. What you don’t hear is just as important as what you do, which is why Bose® Active Noise Cancellation technology monitors undesirable cabin sounds and transmits a non-audible cancelling frequency through the speakers to help reduce powertrain noise.
