Adding a Sub amplifier in X3 Hi-Fi sound to the factory amplifier

[d-rive]

I want to conect an amplifier for subwoofer, does anybody know the connections for that?
The car is X3(2007model, no Navi) with Hi-Fi sound sistem(i belevied is named premium sound in US) (not professional)
I want something like that, but this is for X5. I don't know if the amplifier is the same... http://www.xoutpost.com/articles/x5/s...ctory-amp.html

Is it exactly the same process as in that in the article you posted?

not really. In the left rear back seat you will find several cables, there you can find the cables with the colors wich i have mentioned in the previos post.
If you have any difficulties tell and i will make some photos with the exact location.
