well i can't argue about what the article you quoted says, because the first line said "Unplug the RCA cables from the amplifier/s"
if you disagree with that, there's not much i can do to help.
the inputs can pick up noise, but you have already decided they will.
i said unplug the rcas from the amp, so the amp is not connected to anything.
if the hiss goes away, then the hiss was coming from the headunit.
if the hiss remains, then you know it's from the amp, at which point shorting the plugs would not be of any benefit, since a properly functioning amp should
not pick up noise from it's inputs anyway.
i've used the Xd600/6 and it did not pick up noise nor have a noticable hiss on the outputs

Why don't you stop arguing and actually look into it by Googling "RCA shorting plugs noise troubleshooting"? I think it would be better for everyone, seriously.

i don't need to google something i already know, and have successfully used many times, nor do i need to name drop.
i just had an issue with you trying to over-complicate things
in suggesting an oscilloscope was required to set the gains.
Most JL audio amps i've seen have already done the work for you
and they tell you how many volts should be present at the outputs to achieve max gain. so you don't need to watch the signal on an oscilloscope to make sure it's not clipping.
with troubleshooting any noise, you start removing things one at a time till you find the culprit.
