Heat source found, please give input ?

The car has been locked and parked for 4 days. Not sure what's under the metal body in that area of the car but I'm a little worried. I have not touched this area of the car, so I can't blame it on mods.
Let me know if anyone else feels this? Best to compare if it's felt on another CLS parked in a garage overnight. Thank you in advance

There's a big problem if fuel is being burned while the car is shut off, and it's likely to quickly get out of control if it were - so it's likely not the fuel - which leaves the battery.
I have trouble believing the battery has the capacity to maintain the draw that would be required to keep something noticeably warm for 4 days. I've had an interior light drain the battery after 24hours.
If you're really interested, and the heat is constant, you could drain the battery and see if it goes away. Then you could confirm whether it was coming from the car or not.
My trunk opener has not been working right for a few years, and the motor for that seems to be located in that area. It is very possible that there is a connection between the heat source and that trunk module/motor.
I stuck my hand behind the panel in the trunk, near the factory amp location, and I feel a little heat there. My factory amp is not connected to my speakers, but is still connected to a power source. Next step will be to disconnect the factory amp, and possibly remove it. I thought that turning off this car and locking it would shut down everything

Reverron, you are right bro! I went out to the car, stuck my hand behind the panel, and found out that my OEM amp was extremely hot!!
That thing felt like it was on fire

I pulled out the #6 40amp fuse, and after 45 min the heat is gone. Never realized I had this problem because my car is always on a charger
