Do you mind sharing how you figured out which wires to tap into? Did you just trace those under seat sub wires, or do you know the color codes? I was assuming there would some sort of crossover built in as well, and that you’d probably only have the choice between a prefiltered low pass signal or a high pass signal.

I really love how the battery is just right there on BMWs.

Honestly I used the same method as I used when I added a Subwoofer in my F10, using this very helpful guide.

The wires are exactly the same colour, just make sure you tap into the THICK Twisted Pairs.

(Black Thick Twisted Pair of Wires - Left Underseat Subwoofer)
(Blue Thick Twisted Pair of Wires - Right Underseat Subwoofer)

I haven't checked, but I am sure you will have to tap into the Underseat Subwoofer wires, as there will be no LOW frequencies passing through to the other speakers.
