a4 iso lead question

[glenandem]

hi guys, gonna fit a parrot mki9100 kit to my audi after fitting one for my stepdad in his bmw as i really liked being able to play the iphone music via bluetooth on the speakers!
now im looking for an iso lead and theres a choice asking if i have half rear amped speakers?
its not got a bose system fitted but has a speaker on the right side of the boot?
can anyone help the reg is ng03 soe 2003 a4 avant 1.9 tdi sport

Non Bose is half rear amplified
Bose is fully amplified
They both have a sub in the boot.

Easy answer is to look at the brown connector in the back of the stereo, if there is 4 wires in the center, it's a half amp. If it's missing, it's full amp
