Part of the problem is a lack of standards, even for common terms like "RMS Power". If you get technical, over-driving an amp so it produces nothing but square waves and then measuring the power output with a "True RMS meter" is a legal definition of RMS power (and it will be about twice the "sine wave" power output that most people think of when they hear the term "RMS Power").

I've not actually looked for it but it would be interesting to see the actual test procedure for the CEA certifications. I heard the testing is done at 14.4 volts, which in my opinion is nothing more then the manufacturers agreeing to lie consistently. I did find it refreshing that Boston rates their amps at 12.6 volts, but even their 50W amp is physically larger than I want, and about 3 times what I want to spend. The Blaupunkt digital amp I had was a great size and had plenty of power - just kept blowing up. maybe someday we'll have digital amps that don't self-destruct.

... I'm looking for a physically small 2-channel amp to power the bass shakers in my car...

Exactly how large are these? Would it be possible to cram them into the pockets behind the seats?
