DS3 retrofit Hifi and reverse camera

[Vern]

I have a 2018 DS3 210BHP performance, and would like to retrofit the Hifi boot sub and centre speaker and the reverse camera. I have the plugs for the sub and centre speaker factory fitted, I know I need the sub, boot carpet panel, centre speaker and trim, check the fuse is fitted. Are all the amps the same, or is there a better version? What do I need to enable using the digibox? Is it this simple?
I am a bit more unsure on the reversing camera as can’t find much info about what is needed, so any help guidance will be appreciated, the car does have rear parking sensors, as I believe the camera plugs into the sensor control module?
Any help/ pointer will be greatly appreciated.

May not be that simple, Have you checked if there is a connector present for the amp? Models with the premium audio system may use a totally different wiring harness.
On older models anyway without the hifi system the connector on the back of the radio is directly wired to the speakers, on models with hifi system the wiring from the radio connector go to the amp connector then separate wires come back out of the amp & go to the speakers.
I know on later models the amp is multiplexed & connected on the CAN but earlier ones such as the C6 & mk2 C5 are not multiplexed & could be fitted to any car with a bit of wire butchering.
You would really need wiring diagrams of both with & without the amp system to see if it is feasible.

Thanks for the reply, I have all the connectors in place, any idea where I can get wiring diagrams?

I'd be interested to hear how you get on with this. I've got a DS3P but used to have a 165 with the Hifi pack and the one thing I miss on my new car is the sound from the old one. I was looking at just swapping out the front speakers and components but if retrofitting is fairly straight forward it might be worth me investigating instead.
