Not here you don't. Try it and you'll go straight to the sinbin or be banned completely.

You are asking for help. It is only polite to post in an understandable manner if you want to receive that help, and insulting those who try does not assist your cause.

Honestly, you dont really need 1800W just because your speaker is rated 900W.

100W is more than enough for most home-listening, 900W would blow the roof of your house.

Get more easy driven and efficient speakers and you could get away with a pretty cheap solution using a chip-amp or a solid state amp, that sound good.

this is the cheapest reliable amp to consider (from experience), building such a monster at home is not so much fun, you will probably spend a lot of money with no good result

re power - in case this is meant for pa, the 900W speaker should get some 1200W in amp capacity; anyway what kind of speakers do you have? 900W/15" is a little bit stressed, it would have to have 4inch voice coil at least to take such power without stress

The $200 reference is somewhat amusing though.
