Automotive amplifiers typically don't need a regulator. The screen may or may not, depending on model. Check the specifications fo the screen. If it has an operating range of something like 9v-19v, it needs no regulation.

-On this diagram (found on the forum), the stabilizer is put on the ignition line, is that normal?
Is that correct to feed the screen from the ignition or wouldn'it be better to connect it directly to the M1-ATX? if yes how?
If the ACC is going to power the screen (meaning it only gets power when the ignition is turned on) and the screen requires stable 12v, then yes.

-From where can i get a voltage stabilizer?
It's called a voltage regulator. There are units in the store here for that purpose or you can use power from the computer's power supply, as the voltage has been regulated for the PC.

-What is the role of the Shut down controller? when it is feeded by the ignition, it acts as if it was pressing the "power button" on the PC? So if the PC was off, it will turn it on, and if it was in hibernation, it will come back to the previous "on state"?
Yes.
Quote:
-If the system was hibernating for a week, and the "smart shutdown controller" detects a decrease in voltage levels, how will it send the command to ShutDown the PC? In that case, it is out of question to put a voltage stabilizer "before" the M1-ATX to prevent battery drainage
Hibernation doesn't draw any power, so this sin't a concern.

-How do I test my CarPC at home before installing it in the car?
Use a spare ATX power supply inside.

-The Audigy2 connects directly to the USB Port without any electrical 5V feed? if no, how to connect it to the power supply?
You tap into 5v from the PC power supply.
Quote:
-What about the external DVD/CD-RW? does the models sold on the site also need 5v?
Yes.
Now you've got some questions answered. I answered the ones that I can.
The only one I don't know
You've obviously done some research, which is to be appluaded. You've certainly done more than most newbies that get the carPC bug.
However, you have much to learn. If you haven't seen them yet there are a number of great resources for you to utilize to help plan your project:
