While electrical power is not exactly that important an issue when it comes to normal vehicles, things change dramatically in the case of electric cars, which need all the possible amount of power they can get for actually moving. For this reason, all the electrical equipment installed in such a vehicle has to be extremely eco-friendly and require a low level of power consumption, and that's exactly the case with Bose's Energy Efficient Series sound system, which will find its way into the all-electric Chevrolet Volt.

Apparently, Bose has managed to seriously reduce the amount of power required by this audio system, as well as its overall dimensions. Hence, the new Bose system is 30% smaller, 40% lighter, and uses 50% less energy than conventional Bose sound systems, while the quality of the audio has not been seriously affected (or affected at all, for that matter).

The company goes on to say that in order to create this Energy Efficient Series, its engineers focused on three different areas: switching amplifiers, high motor force speakers and digital signal processing circuitry. As a result, the new Bose switching amplifiers use less energy and generate less heat than conventional linear amplifiers, at the same time driving the new, extremely efficient high motor force speakers to deliver the acoustic output of heavier conventional speakers. These components combine with Bose proprietary control circuitry to deliver good quality sound reproduction, cutting the system’s total power consumption by half.

“The Energy Efficient Series sound system represents another ‘first’ in the long-standing relationship between Bose and GM,” said Brandon Westley, President of Bose Automotive Systems. “Together, we introduced the industry’s first premium, factory-installed automotive sound system. Today, we’re proud to be selected as the sound system supplier for the Chevy Volt. We believe the Energy Efficient Series offers a combination of efficiency and performance previously unattainable from an automotive sound system.”  

Now, if only the Volt had been more affordable...
