Ok so I want to compare the signal coming out of mixer to the signal from the measurement mic.  Would I use a y cable from the output of the mixer?
Yes.  As long as the point where you "y" the output of the mixer is prior to the system eq.  And no, splitting an output does not reduce the level.

Also, in order to determine where to take the reference signal you need to define what you want to measure.
Many PA systems have a speaker processor or DSP after the mixer and before the amps. In these systems it is common to want to measure what the "speakers" are doing to the sound. Speakers, in this case is the speaker cabs, the amps and the DSP. Based on what you see, you make changes in the DSP.
In your case where the speakers are powered and contain a DSP as well you need to determine what you want to measure since you can't make changes in the DSP.
 If I were in your position, and I have been, then I would want to take my reference before my system EQ (typically at Graphic EQ) so I could make EQ changes based on my measurements.
A Y cable is a fine way to get the signal. It doesn't split half each way... Both paths will get the whole signal.

Hi Johnny,

If you are serious about this stuff, get the book "Sound Systems: Design and Optimization, Second Edition: Modern Techniques and Tools for Sound System Design and Alignment" by the one and only Bob McCarthy. You will have lots of questions and there are many answers in the book. It is highly recommended.
