What is this thing in my trunk?

[Battery]

Anybody know what this thing is for?
Also next to the air ride switch is a box. Is that for the keypad on the doors or the wireless remotes?

Might be the amp for the JBL system? That would be my guess

That is incorrect, it is not the JBL amp, I don't know what it is, but I know it's not that.

It's not the amp, as I know where the amp is.

Unplug it and see what doesn't work.
