I hate to further deviate from the original post but it appears that the chatter comes from CEA2006 evaluations being performed by different labs so the quality assurance of this process will never be exactly the same. Until you have one lab doing consistant work this will be a problem and makes the CEA2006 process questionable. You need to go to the guru of testing which still may be debatable.

I've seen that over and over except for nuclear grade components which are 10 times the cost of a commercial grade item. I don't have a horse in this race but your issues with each other is rather minor compared to the article I posted where the power in requirements will never get to the power out without devine intervention.

There is no required governing body for car audio ratings. There are no testing laboratories that manufacturers have to send their equipment to. Any manufacturer can claim any power rating that they want. It’s that simple. (It is important to note that there is an industry standard called CEA 2006-B. Manufacturers are not required to take part in it. When comparing 2 amplifiers that are rated by CEA 2006-B guidelines you can get a good apples to apples comparison. Also, almost all of the reputable industry manufacturers use Cogent Laboratories in Chandler, Az for their testing and independent validation.)
