Afternoon,

I've been trying to find out if it's possible to fit an aftermarket sub and amp to an S40 phase 2 but I'm not having much luck.

My car appears not to have the factory amp in the boot (if that has any bearing).

The main hold up for me is that I have no idea how an aftermarket setup would interface with the audio cabling in the S40 as I believe it's all fibre based.

Can anyone shed any light or point me in the right direction of an existing article please?

Thanks
