It's not about being better or worse, its about being the right component, you are speaking of these parts as if they should be in the 15K. They are more than adequate for this amp's ratings. Why the hell would a 243 be in a 4 channel class A or B amp?yeah you are right actually the motorola 243 is better //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
now you have made it look even worse lolz
It sounds like you have knowledge of the parts, just no idea of how to apply it.
The 9540 is p-channel, Is rated at 175c. Vdss -100v, Rds(on)=0.117ohm, Id=-23A
The 243 is N-channel, only has ratings of 100c. Vdss 150v, Rds(on)=0.22ohm, Id=16A @ 100c.
The 243 is not as suitable for a class a/b amp as it is a D. The 9540 is actually a very good component
