Rs2 active rear speakers

[Bruno]

I want to use the rear active speakers in my rs2.
I found the signalcables to each speaker.
Right:
Negative:Brown with black stripe
Positive:Red with green stripe
Left:
Negative:Brown with red stripe
Positive:Blue with green stripe
Can i just put on rca plugs on these wires?
Anyone who did this before?
When i turn on the speakers there is a lot of electrical noise(generator turbo sound)
That sound is often a typical reaction of bad amplifier grounding.
There is also 3 cables i dont know what is.
Red with brown stripe
Grey with red stripe
Red with yellow stripe

These are use to display RDS info on the autocheck LCD if you are using the Audi Gamma system.

@Bruno - Use this schematic... The wires you mention make sense, but check that active speaker gets good power and ground.

I think the red wires are switched 12V
The white wires are 12V only when radio is turned ON
And of course brown wires should be good 0V earth

Note how the 0V earth brown cables from rear amps connect to earth via T6k - the same plug as the RDS info... Make sure that is wired up properly at pin 2... You can ignore the 3 x RDS pins.
