The watts ratings has gotten so bad in the car audio industry that they finally developed a standard to published watts - CES i think. Not sure what the testing details are, and could all be hype, but given that only the higher end companies seem to use CES watts, i think it is have a good impact on truthfulness. I wish the home industry would do something similar. It is frustrating and forces you trust companies. Not good.
