As the HK amp is digital, it can vary its power allocation (as I understand it), so to gain the maximum benefit i fitted a Hertz class D amp, just to power the new subs.
With the HK amp no longer having to drive these with anything other than a signal to the Hertz, it allows better power distribution to the remaining 11 speakers.
The resulting sound is fantastic, with no distortion.
I went with the Audisons based upon reviews, but several manufacturers produce similar units designed specifically to directly fit BMW's enclosures.

Bump. How did you connect the HK amp to the mono amp? Do you still recommend your uprgwde? |
It's not a mono amp. I've used high level inputs into my Hertz amp by taking the sub outputs from the HK
And yes, still loving the sounds
