Marking the polarity of the speaker wires will make it easier to connect the
existing speakers to your car radio. Consult the wiring diagram of the existing
head unit before disconnecting any wires. If you are not positive of the polarity of
the existing wires from the speakers to the head unit, install new wires.
1. While the old unit is playing, disconnect the wires from one speaker.
2. Take a length of masking tape and fold it around the wire so it forms a ag.
3. On the masking tape mark the polarity of the speaker wires (+ & - ), as well as
left or right, and front or rear.
4. Double check that you marked the rst speaker correctly by checking that the
speaker wires are the same at the head unit.
5. Repeat this procedure for all of the speakers.
