Retard Question Wiring

[Deutscher]

Hi,
This is kind of a noooob to the max question.
Which wire is positive and negative?
Plain white or white with black stripe? (Front Left speakers)
I need to connect it to the "Tan" and the "Grey" pre-existing wires.

The striped wire is for positive,(assuming your talking about the speaker wires on your headunit wiring harness) the tan wire connects to the positive terminal on your original speaker...

The plain wire is positive and the wire with the line is negative with most manufacturers.

[Devils_Thunder]

plain is positive and the one with the trace is negative
