I will not talk about the layout as Eva gave great advice.

But something I don't understand. You mean that the people in your country prefers a cheap Chinese 2 steps class H at 40kg for 2x3000W 4ohm than a Lab.Gruppen FP13000+ or Powersoft K10 or MC2 E90 with so much more dynamic and reliability at merely 10kg ?
What you should had say is that people in your country has no money to afford current great high-efficiency amplifiers (and I don't talk only for Romania, everywhere is the same).

But if someone come in the market with a SMPS + Class D amp at 2x3000W RMS 2ohm at 10kg and with the same price than the current Chinese mammoths (and it's possible), people will start to buy class D ! no doubt about it...

You don't think so ?

Hi Arthur!
You say it is possible at the same price?
I say it is possible at lower price.
In class D for 1kW or above the required power semiconductors are less, the required PSU is less, the required heat sinks are less.
It is just a question of time until also the low cost manufacturers all over the world (not only China) will gain the necessary know how and the difference in sales price will melt.
Let's not start to discuss if this is good or bad, it's just obvious.
