Need Confirmation: Newbie MOST Questions

[robgar]

Okay, so before you ask, YES I have scoured the forum :-). I beleive that I understand the MOST system as others have described it and I am hoping for confirmation of the below statements.

I bought a 2004 996 Carrera Cab yesterday (yipee) and first order of business is to upgrade the factory audio components. This is a USA car. I'd like to move climate control down (saw a post to do that), add a double din nav head unit, upgrade AMP, replace speakers, and add subs in rear under seats.

1) I assume that being a 2004 model with a glove box that I do have the MOST System (correct?)

2) As I understand it, the MOST System runs fiber from the head unit to the AMP (I have no CD Changer), but not to the speakers. The speaker runs are copper from the AMP. (all correct?)

3) The audio information that displays in the console behind steering wheel is also operated from the MOST System (correct?). If not, what controls that and if I upgrade the head unit will I lose that functionality (no big deal really)?

4) What speakers does the AMP power? I have 2 in dash, 2 in door, and 2 in rear. All of them?

5) Now this is have not researched ... what are the speaker sizes for these 3 locations? I assume 6x9 in the doors, but the dash and rear appear to be the same yet smaller than the doors.

6) I am hoping to place 8" subs under each rear seat (facing forward). Is there space there under the seats to do this?

Any other gotchas I may not have discovered yet?

Thanks for your time.
