970 connection to subwoofer amp

I need to connect the 970 to an NHT A1 full range mono amp, used to power a 10" sub. I was told that I could come out of the 970 with a low cut signal, (needed because the A1 has no crossover control. Where do I connect to accomplish that

If you are powering a sub with the amp, you'll want to connect to the 970's subwoofer output. This signal will already have been passed through the 970's bass management and will therefore be subwoofer-friendly.

Thank you gonk, it sounds great.
