No. The 13.2V and 4 ohms graphs show that clipping begins when the output power is halfway between 10W and 20W. 1% distortion is very obvious to most people and graph shows 18 to 19W. I never play an amplifier so loud that it is clipping. Do you?AudoGuruit seems that you're referring to this graph. From graph it appears that the distortion is above 10% at approx 25% watts that too if the supply voltage is 13.2V. In car audio the supply voltage is lesser than or equal to 12V. So I'm thinking that the distortion would be less than 10%.
The curves in the datasheet show that this and most other car amplifiers cannot produce power as high as 45W or 30W.Ok thanks. Now coming to the intensity of loudness heard by human hear which of following is more louder.
1) 2 speakers with 45W each.
2) 4 speakers with 30W each.
