I have had success with that in regards to it working, but the issue is you're then limiting yourself to the frequency filtered by the amp to the OEM subs, which is something like 50hz and lower IIRC. So yes, you'll get a signal and your newly added sub will work, but you're only going to get the super low frequencies coming through. For most people that might be acceptable, but for me and the variety of music I listen to, its not.
On the flip side, running off the rear speaker post-amp outputs, you'll again be limited in frequency response but more of mid-range freqs, which are good for kicks and punches, but you'll miss out on the low sub frequencies.
You can do a little fine tuning to bring in marginally better freq response, but in the end you're still limited to the output of the factory amp, and since the HK system uses weird spec'd speakers, the amp output isnt ideal.
What I'm trying to do is run the aftermarket amp off a pre-amp, unfiltered signal. Typically this is achieved on aftermarket head units by RCA pre-outs.
