Hey there, i am just wondering what these connectors might be for? they are in the trunk behind the amp/cd changer and are not for the cd changer or amp as far as i can tell because they are plugged in. at the same time my radio has recently stopped working and the fuze it still good, Any ideas?

Thanks in advance!

 

The two in the second picture relate to an ancient analogue carphone installation, which someone has likely removed some years ago. The white plastic plug may be the same, but form your question, are we to take it that you have the premium harmon kardon sound system, with the separate amp in the boot?
