“One of the difficulties implementing
the ICE module is its hungry demands for a powerful input signal. The 700 watt
ICE module has low impedance (around 8KΩ) which, if not properly buffered,
Little bit of obfuscation. A lot of Class D OEM modules have both buffered and unbuffered inputs. It is up to the manufacturer to either use the default, or build something else.
This lets you do tweaky things like a tube input buffer, diamond, whatever.
My point is, no end user is really ever going to feel or suffer from the low impedance inputs.
