What wire brings power from the battery to the radio?

[Rasteirinho]

So, after all i was wrong...
One of the wires that i thought was for the speakers, is the power source wire.

In resume for who needs:
Wire white with a black stripe - Ground
Wire white with a red stripe - Power Source
Blue with red dots - ACC signal
Green with red dots - Taillights signal

There are more 4 wires besides these ones, those are for the speakers.
