Can any one guide me to a good tutorial of designing a 2kw Audio frequency Class D power Amplifer.
Any Circuit diagram or application note.
I know that no speaker I have (or am likely to ever have) can take that much power, and the amp would be a waste of money. Should someone be silly enough to pay me the AU$12,000 I would charge to build a mono version of the amp, then I would happily do so. So, I am confident that it will work as described, but it will almost certainly never be built by me. I hope that my readers share my pragmatism.
The power supply needed for an amp of this size is massive. Grown welding machines will look at it and cry.
2KW amp? Holy hearing loss Batman! Why so much power, do you really need that much power?
Is this for a guitar amp?
Maybe you can build a Tube amp, Lots of web sites with tube amp schematics. I found a 400W amp at this site.
Every year there is a max sound level competition for a car's sound system in a town near my home.
I went there one time but the very loud sounds and smoke forced me to leave.
On some cars the windows break.
That's why one should buy a Marshall or a HiWatt -- or even the old Ampegs. They last, aside from the occasional replacing of tubes.

Considering their size, the W7 voice coils are extremely light in weight. We use aluminum-alloy wire (instead of conventional copper) and a specific winding method to achieve the electrical properties that we deemed necessary to achieve our design goals. The light weight of the coils helps keep the overall moving mass down at manageable levels, which is extremely important for efficiency and sound quality reasons.
