Default Bose retrofit

I have almost all options on my 02' A8 and one of the missing options is the Bose audio system. I've had it in my previous A8 and i'm missing it most of everything ever in a car!
I know that the retrofit IS possible but I want to know if I have to install all new cables or do I just connect new speakers and the amp with the headunit?

You have to replace the whole harness, from the boot up to the head unit, as the Bose system has larger speaker wires and low-level outputs for the amp which the standard system doesn't have. All the antenna cables for nav, radio, tv etc are also in the same harness.

Seats, carpets, rear shelf and centre console out to get to it all, but its easier to do that than to try and pick apart the harness.

I think IT did it a long while ago and documented it too.
Pretty big job as MJ has said.
2003 D2 FL S8. Irish Green Pearl/Beige. Solar sunroof, auto-dim mirrors, electric rear seat functions, ski hatch retrofit; extended leather. Aftermarket DVB-T, reversing camera and full XCarlink (Bluetooth etc.).
2016 Volvo V40 T5 Cross Country (4WD) with ALL the toys including adaptive cruise etc. etc. Osmium Grey with Blonde/Charcoal leather interior. Polestar performance "optimisation". (A much rarer model than a D2 S8 by the way!)
Finally: gone, but not forgotten.....
1998 D2 PF S8. AgateGrey/Platinum. Every option (I think) except electric rear seats, tiptronic steering wheel, ski hatch, towbar & dimming door mirrors.
e.g. Cruise control, NavPlus/TV, Bose, GSM, Xenons, Solar roof, Parking sensors, Alcantara/leather everywhere of course. (internal dimming mirror added later)
1998 (very early) Ford Focus 1.8 Zetec; ABS/TCS, Heated screen/mirrors, Aircon, Auto-dim mirror, Leather, Trip computer, Cruise control, OEM Ford SatNav with CD changer.

By modern standards itís just an average system anyway. Youíre better off getting an upgraded headunit and speakers.
Future plans: full exterior detail, something special with the interior and sub woofers
