So I have taken several measurements of a car audio amplifier that’s claimed to be Class A to 30watts and then AB from there up to 165wrms per channel at 1%
It’s a four channel and has an idle current of 8a… I am very sceptical of the claims, I would expect a current draw of 20+a for class A up to 30watts so approx 120watts of power dissipated and a lot wasted (voltage is 15.4v in my car)
I’ve taken some measurements and they don’t look pretty either to me
