Harman Kardon upgrade HELP NEEDED please.


I have 2009 CLS and it has this system NTG 2.5 with navigation and twin tuner AGW

I've bought all Harman Kardon speakers but Im unsure what amplifier do I need and is it just plug and play or do I have to do wiring etc?

Can someone please help?
Thank you,

You will need to use MB STAR (diagnostics) to erase stored fault codes, check amp flashware is current, and code new amp.
