I recently bought my first Jeep. A 2013 JK. It used to have a lot of stuff judging by all of the extra relays. I have a lot of questions. Firstly, what is this? It’s tucked behind the glove box

That is more than likely a bass volume control for an aftermarket subwoofer.

I'm assuming your Jeep has an aftermarket stereo? If so, turn it on (something with a lot of bass), turn it up, and rotate that knob slowly. It should most likely increase and decrease the volume of the subwoofer.

That's my best guess, as that is clearly something custom made and aftermarket.
