I thought some of you would be interested in this from the Consumer Electronics Association.

CEA Adopts Standard Rating System for Measuring the Performance of Mobile Audio Amplifiers Arlington, Va., June 26, 2003 - The Consumer Electronics Association (CEA) announced today that its Mobile Electronics Committee (R6) has adopted a standard rating system for measuring the performance of mobile audio amplifiers. The new standard, designated CEA-2006 - Testing and Measurement Methods for Mobile Audio Amplifiers, was created to make it easier for consumers to compare technical characteristics that determine the quality of mobile audio amplifiers. The standard applies to headunits, separate amplifiers and subwoofer amplifiers. Products that comply with CEA-2006 will be authorized to carry a corresponding logo.
"This standard benefits retailers and consumers by providing a logical measurement tool that helps demystify audio," said Pat Lavelle, president and CEO of Audiovox and chairman of CEA's Mobile Electronics division. "The ratings and disclosures provide a consistent, technically reliable resource for consumers to use when making purchase decisions."
"CEA-2006 fills the void that previously existed when consumers needed a uniform measurement method to compare different products," said Ralph Justus, vice president of technology and standards for CEA. "This standard helps clarify product differences, particularly regarding rated power output and distortion, and helps increase consumer confidence about their purchase by helping to educate consumers about the product's benefits."
The primary measurement criteria outlined in CEA-2006 are power output, the signal-to-noise ratio and total harmonic distortion plus noise (THD+N). With the new standard, consumers should expect to see two primary ratings - an amplifier's primary power output in watts (RMS) and the signal-to-noise ratio in dBA. The primary power output in watts is measured at a level with less than one percent THD+N to indicate how much continuous power the amplifier delivers at that low distortion level. The signal-to-noise ratio is measured at a reference level of one watt. A larger signal-to-noise ratio number indicates more desirable audio and less noise in an amplifier's output.
CEA-2006 is available from Global Engineering Documents at http://global.ihs.com. Additional information about CEA's Technology and Standards department can be found at www.ce.org/standards.

Yea, I got wind of this story about a week ago. I wouldn't jump for joy just yet. Lets wait and see how many manufactures jump on the bandwagon. I suspect many will not want to participate right away.
