Saving energy is entering the world of car audio.  Bose has announced it will introduce its Energy Efficient Series sound system in the 2011 Chevy Volt.  The proprietary Bose system is 30% smaller, 40% lighter, and uses 50% less energy than conventional Bose sound systems, while delivering premium, high-quality audio.

Bose engineers focused their design efforts on 3 areas of technology in designing the system: switching amplifiers, high motor force speakers and digital signal processing circuitry.  Bose switching amplifiers use less energy and generate less heat than conventional linear amplifiers to drive new, highly efficient high motor force speakers.  The company says the combination of these components and Bose proprietary control circuitry deliver sound reproduction at concert hall volumes, while reducing the system’s total power consumption by half.
