Suggestions for earthing EAW crossover

I've never heard of a box that needed to be grounded for a crossover to work. As above I would have thought sense wires and some bullshit proprietary controller but I'm still not sure exactly how the earth could work. Any chance its something to do with 100V line runs or the drivers are a weird high impedance so they can daisy chain lots of them? I really want more info on these boxes

AFAIK all of the drivers in the box are 8 ohm, well not too sure about the HF but the mid and LF drivers are for sure.

Binning off the crossover entirely and running on an NL8 was my other possibility if I couldn't get these to work, but I've already bought all the cabling and installed dual NL4 cnc cut panels on the back with connectors and wired them up, and running 3 way would need I would need to buy another amp and another bigger amprack to fit it all in, and would mean all the work I had done so far was useless which wouldn't be ideal! But ive got to the frustration level point right now where I was about to rip all the x-overs out, yes 

All good , just to finish off ,in a John Cleese voice  "I dont want anyone to connect the yellow wire to anything ,and I want to make this absolutly clear ...even if they do say johovah"

They might actually have a "ground". Since they were installed at a stadium, they might have "earth" to protect the system from lightnings.

And if there is a diagram saying it's an Earth then it's probably worth asking .  I suspect you should ignore the diagram, I actually wrote down the wiring colours I used but I'm 200 miles away from the boxes and can't confirm whether this is wiring I attached or wiring from the box. I think its the wiring already in there as we have Yellow. I also did some tests to check I had the correct phases but I can't remember what. Anyway ->  LF Black negative LF Blue Postive HF Black negative HF White Postive Yellow Monitor

Thanks mate! I had the yellow and the white confused and that was where my issue is. I originally cut off the white thinking it was a redundant earth when i should have cut off the yellow. The diagrams from EAW show an earth. And the socoplex cables that plugged into them had 6 black cables and a yellow and green cable (which must have been monitor) which is the colour for earth in UK which is where I got confused, went through a massive ballache setting up a trade account and signing an NDA to get the stuff aswell. Have the whites still inside the cab and its all done with choc-blocks so easy procedure to switch it all over :)
