The mod is complete.
I removed the mmi unit and glovebox to gain access to the wiring and tapped into the rear left and right channels and a 12v supply behind the fusebox and run the wiring through to the boot.
Connected the high level inputs to a 200w jbl amp which fits nicely at the side of the spare wheel. Tapped into the accessory socket live in the boot which is ignition live to turn the amp on and off and then ran the wires from the amp to the dual coil B&O sub. Also had to get the longer nut and bolt that holds the spare down as the standard one is too short to hold the sub down.
The result........ ****** AWESOME.
total cost £200, should have added *** at order but I didn't so this has worked out really well.
@JordanQuattro thanks for the help sourcing the Audi parts.
