8v B&O door wiring

Hi.
I’m gathering all the parts to do a B&O retrofit on my s3 saloon. I have an interior loom on the way which has the wiring up to the doors. I had a look last night at the door loom connectors and realised they are a big block with no real space around them to run additional wires into the doors.

So I have a couple of questions.

1. Anyone who has ran additional wires in to the doors.... did you put pins on your speaker wires and utilise the factory door connectors?

2. can I tap in and utilise the existing speaker wire looms that are already in the door for the standard sound system or does it need to be a better grade wire for the B&O?

If you want to run wires from the car side to the doors then you will need to use the door connector block and use the male and female pins.

I figured as much. I’m just trying to find a pin out for said door connectors. There seem to be large pins and small pins. I don’t know which would be best.
Have you any idea if the stock speaker wiring in the door for the Audi sound system is good enough for the B&O speakers?
And do Audi sell the male & female pins required

I don't really deal with the audio side so I couldn't say sorry, lighting side I could help.

I can supply you lengths of wire with the correct pins crimped onto the end if required - if I get chance tonight I will have a look at the wiring diagrams to see if there is any difference in wire size between the 2 systems. Drop me an email with the vin of your A3 - sales@rocketwires.co.uk

Has it been worth doing?
Did you buy second hand?
Is there much wiring?

Yeah it was well worth it.

Overall, the installation wasn’t that difficult at all.

I purchased the following:

A complete interior loom from eBay.de. €120

A complete 14 speaker set from eBay.de €295

Amplifier from eBay.de €100

Parcel shelf with speaker cut outs (saloon only) eBay.de €100


I also ordered from Audi,
The amp bracket,
Amp cover
Double microphone
Front door speaker grills
Various bolts and screws which you will find listed in the definitive B&O retrofit thread

Thanks for that
Where is this 'definitive B&O retrofit thread' I have searched several times even before I asked on this thread and nothing comes up, I have been to the ICE forum and no one answers there????
