Harman Kardon System not working.
I have a 2006 mercedes c55 with a Harman kardon system and when I got the car in the trunk everything was disconnected. After a couple hours I got everything connected but no sound so I tried different things out still nothing. I checked the fuse and I tried reseting the system buy taking the fuse out and turning car off for 15 mins and after all the stuff I found online nothing worked. So I checked to see if power was going to amplifier and it was so I thought it was a bad amplifier got a new one and it still does not work. Even after installing the new one I did all the steps to troubleshoot and nothing works. If you want pictures of anything just ask.

seller probably pulled a fast one on you so you couldn't test the stereo when you inspected this car before purchase.
did you ask seller before purchase why all plugs were disconnected?
what was seller's lame excuse?

there's a reason why amp in trunk was disconnected when you bought the car.

What do you mean buy connect to star? And yes I checked the fuse box and I had some of them taken so I replaced them and checked all of them. The wires look fine in the trunk I took everything out and looked at them and I noticed that I have 2 wires in glove box one orange and it's just there and one that has a connector but I think it's for cd changer.

The CD changer is part of the audio fiber loop. You won't have sound of any of the following have a problem. Headunit, CD magazine, and amplifier. Replaced the whole system in mine since the loop fails a lot. Therefore I have each piece if you need one or all, they worked when removed.

Oh I forgot to mention I called mercedes info from the car and I got connected to a guy and I could hear him from the speaker in the middle of the dash I don't know if that means anything but weird.

That audio fiber loop is called the most loop. The fiber is wired in series so you take out 1, you have to bridge the gap to allow it to work. For seeing if that fixes your issue you can get a most loop bypass. The blue connector in the trunk is an antenna wire and two are for the radio and 1 for the gps I believe. If I remember correctly there was a couple boxes that were mounted by the passenger tail light that have this connection. The last cable I have no clue. When I get home next week I could get back there and look however, I have modified many of connections back there so someone else might be better help. As for the speaker working if that system doesn't go through the headunit then it would work. I do know that 4 wires, 2 pairs, run to that speaker don't know if that has anything to do with it working but 1 pair could be for that system.

This is how the trunk looks like atm I have to boxes on the side and the AMP on the floor
This is the connector that I have no clue what it goes to and it looks like it goes inside the car.
I have this fiber optic cable just doing nothing has not connector and I cant find one it goes to and this one goes into the inside of the car to.
and is this the Loop bypass youre talking about and where does ti connect to the AMP?
Thank you so much for your help I really want the system to work and I dont want to spend lots of money buy taking it to a shop and sorry about how little I know.
