TDA7250-ST - great resource(?)

[Polimorph]

I tought it will be a good ideea if I start this thread because TDA7250 starts to have more and more users.
This is one of the best driver for power audio amplifiers, we are limited only by our poor imagination, 'cause the chip really rules!
Here's its datasheet:

I would like also to give for now an example of a really good application version (2x200VA/2 ohm)

Now I have a question too. If there is someone really kind to anwer it I'll be more than "enchante". Here it is: "how can I bridge this amplifier to obtain 1x400VA/4 ohm without any phase switching IC but with a resistor between one output and other input, or something like that?" I know that it's possible.
