Mkay, I just got my USB hub so I should be able to get some stuff tomorrow.
Anyone have a source to a track that I should play? Or will the pink noise uncorrelated I used for tuning work?

Correlated pink noise, preferably periodic set to same settings as rta window.

1) It works for individual speakers, but not for pairs. Correlated for pairs. Otherwise you will never be able to hear a center image. Here is 10 minutes of Periodic Pink Noise https://drive.google.com/file/d/1c5w...ew?usp=sharing
2) Individual and pairs would be best.
3) I already see you are dropping about 25db from your low frequencies to your highs, that is quite a bit and would be a big issue that is easily fixed. You need to turn up the volume on the tweeters and mids and/or reduce the bass volume. A lot of the areas that you low in, also correspond to cuts in your EQ.

Got it, thanks. I'll turn up the tweets and redo the measurements. I think the reason for the difference in volume is because the highs were bothering me when I had them at the same volume as the rest of the system. I actually just turned down tweeters even more yesterday evening.

Right now you seem to be at a whitledge curve, which is a curve quite a few don't like. Even then you have some big wide bumps and dips which is going to cause an unbalance in the sound.
Try a half whitledge
Or Justin's (I did this in my wife's SUV and actually really liked the results)
Or JBL/Andy which a lot like: I personally do this with the dip Justin's curve has above in the 2-4khz region.

Thanks!
I see the graphs say "to be exported" Should I be like creating these curves for use with Helix's RTA or do I just tweak my EQs to recreate the curves?

I would suggest downloading REW and using it to record the RTA of the system. You can have the curve in the background and see how close you are to matching it. It is better than the helix software unless you are using the AUTO eq, then adjust the auto eq curves appropriately. You can set a curve on the helix EQ screen (you can see it lightly in the background on your picture) but it isn't the easiest thing to do.
Also, those curves were created using Justin's spreadsheet (stickied in the tuning section I believe)

Here are some helix curves to import into their RTA

I am indeed using the auto EQ w/ Helix.
I was having weird issues with gain on when using REW. For some reason REW wasn't detecting audio levels well compared to Helix, but I'll give it another shot. The JBL/Andy curve looks quite nice.
