Don't you mean disconnects the ground not opens it up?

when that happens it opens up the ground which is supposed to be there.... creating resistance between the headunit and the amp...AKA ground loop...
and i do believe he's using rcas .... he's tapping into the harness so he doesnt have to run wires into the door

It's not actually because they cause ground loops
It's because the couplings in the back of their head units (which all head units have) which have the purpose of resisting the whining noise, tend to blow when the RCA's touch anything with even a small electric charge, as small as a car static shock.
So indeed try this
Ground the shield of your RCA anywhere to your car and see if it stops.
If not, you probably have a bad ground connection, and it might not be your amp.
Now you say you tapped into the speaker wires in the back of your head unit?
In all honesty, you really should be using RCAs in the first place. Use RCAs as well and see if it solves the problem.

Now, now boys.... I'm gonna send you both to your rooms if you can't play nicely.
Borrow a deck from one of your bud's (not another Pioneer) .... swap it out with the Pioneer, and watch the noise fly away.....
