300tdi stereo?

Ive got a 300tdi to which ive put my Kenwood stereo in but i seem to have lost power to the rear door speakers/amp. I do now have some spare wires lying about but I cant figure out what theyre for (the haynes wiring diagram confuses me easily) I know some of these must comtrol the dash buttons but im not bothered about these its just the rear door ones i need help with.
The spare wires I have are 1 block with Yellow/Brown, 2x Blue, Red and Black. And another block with just Red and Black wires, could someone please tell me which ones if any power the rear door?
Thanks in advance

There's already a thread or two on this, pages of info so do a search.
You need to connect to the pre-amplifer output at the rear of your head unit to the door amp using a phono patch lead.
The wire colours at the door amp are as follows:
There are three circuits to the rear sub. 12+v amp power taken from the head unit supply, (light green/orange wire at the amp, also a local earth wire which is black at the amp).
The 12+v amp switching wire (purple/yellow at the amp).
The audio signal cable (black & white wires in a screened cable).

Kenwood units are good as you can also get a patch lead to interface with the existing dash controls so I understand from the forums.

thanks mate
