Hello! Im new to this forum, I hope I post this in the right section.
so.. long story short, I removed left cover in trunk and was pretty suprised to see nothing. I have seen in picutres that there should be at least amp. Any ideas why? Did previous owner sold those parts? What is that blue connector and antenna looking things? Satalite module wires?
Have a nice day!

 

There are may variations. If your sound works, you probably have what the car was ordered with and that is just for something else, like Sat Radio or fancier amp or such.

 

Pull the next lining out there should modules there. Mine does not have any modules in the location you are showing.
