UPDATE:
I took my car to nissan to have them turn off the lights that came on and after keeping my car a full day they called me back with some interesting news. They said the speaker wiring is all over the place and they're afraid to touch it. They said that they had drilled into the floors and that it's just a mess. Nissan recommended I take it back and have them fix the wiring without damaging anything so I can keep my warranty.
In my eyes, wiring is wiring, I can always redo it, cut my losses, file a lawsuit or whatever, but I just want my car to be ok
I'm really ocd about keeping everything meticulous and new and I think I'm at a point of no return with this one.
