Two unknown cables behind the stereo of my 2010 Mitsubishi Endeavor

There are two cables that fell out when I pulled the stereo out a little ways in order to remove my glove box. I don’t know where they came from or what they are for. I have looked at videos and haven’t seen them at all, if you know anything about them and have advice, it would be appreciated.

They look like the antenna and power supply wire’s for my after market XM radio maybe the previous owner had one and did not remove them when they took the radio out.

I am starting to think that as well because there Are some holes drilled into the top left side of the thing and I haven’t seen that anywhere else either. There also isn’t any room for those wires elsewhere to be run so it has to be that. Thank you for the help!

I would not be worried about it if every thing else work’s as it is supposed to. the hole’s were possibly to mount the XM the two wire’s plugged into the back of the XM radio.
