The smell is definitely coming from the cable. I can touch it, and my hand stinks. Further up the cable, close to the jump start lug (where it runs on top of the strut tower), it's also pretty dry/charred looking as well. I don't think it's actually melted yet.
I also noticed that the whine through the radio (which my car has always had), was a bit worse over the past few days, however reduces quite a bit as I reduce electrical load: turning off HVAC, unplugging phone charger, etc. All of this leads me to ground issues.
Going to start with the common issue on the battery ground.
Edit: this is wrong as well, but the ground issue is fixed!
