Van - rear speakers?

[Jmorris1408]

Hi all, I'm wanting to add a couple of rear speakers to my berlingo van. does anybody know where abouts in the back I would pick up the speaker wire that runs from the head unit? I'm presuming it runs so far, possibly to where the speakers would have been in the car version... any help would be appreciated. 

Ps, I have a nearside sliding rear door if it makes any difference.

Firstly, is it the standard head unit?, if so you wont have a fade option activated at the moment!

I've done it on mine and its not that straight forward!, there were no speaker wires running to the rear!

I needed to buy an ISO connector off ebay, remove the original cables from the original ISO plug and insert them in the new one along with the extra rear left and right cables!
Then using Lexia I activated the fade function on the radio!
I'll check and see if I still have photos, although it was over 2 years ago lol
