Managed to get out there today and fit the new front speakers.
Infinity Reference 6010 component set (16.5cm mid woofer, crossover, 5.0cm tweeter)
Required the BMW Mini speaker adapter rings though. But they were only an extra £9 or so.
The tweeters are mounted to the original tweeter position inside of the door mirror, using the same bracket.
Until I devise some way to mount the crossovers safely inside the door, they are currently wrapped up to protect from water/leaks.
Wires are all hidden away inside the door where possible, and all standard wiring is still in place to return to OEM should I sell the car.
With the door cards back in place, you'd never know....
...Until you turn it on!
