Citroen C3 a51 adding subwoofer and central speaker

[FerixNB]

Hi,
I installed in the Citroen 3 A51(II) 2012 1.4Hdi Van subwoofer and central speaker. I've got the factory leads, but there's no radio response. Is this about the radio? It is an RD45 with bluetooth and microphone. I saw a similar topic on the forum in DS3 but I have power on BFH1. In the subwoofer connection section I have two more plugs.What could they be for?
