Hi, all the stock speakers are being replaced so the crossover issue will disapear.

On the back of my BMW wide screen SatNav headunit there are two male connectors, which the 2 female connectors fit into (from the wiring loom).
Looking at the headunit from the back, the top one is blue, the bottom one is white. This corresponds to the colours of the male connectors which are also blue and white.
The connectors are slightly different in shape (forcing you to use blue to blue and white to white), however they do have the same number of pins.
In the previous post, it was said both are blue (in the pdf).
In the posts picture, one of the connectors seems to be at the top of the headunut, while the other is towards the bottom.
However, on the back on my headunit, they are positioned one above the other.

So can someone tell me which is the X18801 and which is the X18802?
This will be vital as i need to tap into the correct one to get the power and ground/negative for my aftermarket headunit.
