Hi all

New owner of a Outlander Diamond 2008.
There is an aftermarket stereo fitted (dasantia) subwoofer and rear view camera not working although I’ve realised the amp under driver seat is missing.
2 questions - is it just a case of sourcing a replacement amp to get the sub working? Or will it not function with an aftermarket stereo?

Camera - as far as I can tell factory fitted and I haven’t yet looked at the back of stereo to see if physically not connected but are they known to have issues with aftermarket equipment?

thanks
