FWIW, I like my noise cancellation too and would prefer to leave the stock system intact for now. After driving through the big hills in PA without Noise Cancellation, I have come to find the drone pretty annoying.

Don't quote me, but this should be perfectly fine to use for that. It is a rather expensive way to go about doing that, but Yes. The harness used in connecting the device is a T harness, so signals pass through the unit, and back to the OEM amp (which must remain hooked up). You would simply utilize only the Subwoofer output on the M650, and run that to you amplifier. Keep the OEM speaker wires intact at the amplifier and you're golden. It even has a toggle witch that allows you to use a separate sub-bass controller to control subwoofer bass on the fly, or control the bass signals going to the entire speaker system.

see pages 3 and 4 on the manual
