8P Bose; half or fully amp'd?

[Dines]

Ok - I give up... I've searched and searched and searched and then searched some more. I even tried asking Audi (I know, stupid idea...).

How do I tell if my Bose system is half or fully amplified?

It's a 55 plate A3, (8P) with Symphony II double DIN (6-CD Changer).

Any help or pointing in the right direction would be appreciated!
