Bang and Olufsen (B&O) Subwoofer / Amplifier Add-On DIY

then just tap the right and left rear speaker for the full spectrum and use the amp's cut-off to tune it down.

The B+O amp int eh back powers all the speakers, not just the sub, so it's just a matter of tapping different wires.

The left and right speakers aren't filtered? I would think that they are cut off much higher then the sub would be

they could be, I am not positive, I know if you need to tap a high powered wire and use a LOC to get it into an RCA cable that you typically tap the rear L and R speakers to do so giving you the full spectrum.

I wouldn't imagine the stock AMP is so advanced that it's filtered, but it could be.

I mean the proper way to do it would be to run something similar to a JL Audio Clean Sweep and pull from the stereo outputs from the MMI to begin with. But now you are tlaking about adding a step that could cost more than the sub and amp put together.

If you were seriously considering upping your audio quality, this would be a no brainer, but for people looking to improve the stock sub with something a bit more powerful, than tapping the stock sub leads is just fine.
