Coiling XLRs.... yes or no?

XLR wires carry differential signals. It will not matter that much if you coil the wire. Especially only 3m long. You will not even hear the difference one way or another.

Note on a lot of pro audio stages, all the XLR cables are coiled up to keep the excess lengths tidy.  As a sound tech, I've been coiling balanced cables for nearly 40 years and can't hear any difference in coiled vs. uncoiled.  Hence the reason for using XLR; they are quiet no matter how you route them.

both ways sound great

I have routed it well. If there is a difference, i would need to record both ways and listen to the recordings back to back to be able to tell for sure. I like to think there is a difference at least; and its nice piece of mind.

Found a way to route it through my cabinet without interacting with any other cables and the way i did it you cant see the cables

Thanks. Good to hear the results of your experiment.

Coiling will increase inductance, but only slightly and not enough to make an audible difference. The studios and stages where your music is recorded are full of hundreds of XLR cables coiled up. Of couse, most studio kit is balanced and so common signals are cancelled.

One possible choice is to "fold" the cable in half (i.e. stretch out the cable from both sockets) and then coil.
