2. Mark Polarity of the Speaker Wires

Marking the polarity of the speaker wires will make it easier to connect the existing speakers to the VRCD220S. Consult wiring diagram of existing head unit before disconnecting any wires. If a wiring diagram is not available contact the manufacturer.

1.While the old unit is playing, discon- nect the wires from one speaker.

2.Take a length of masking tape and fold it around the wire so it forms a flag.

3.On the masking tape mark the polar- ity of the speaker wires (+ & - ), as

well as left or right, and front or rear.

4.Double check that you marked the first speaker correctly by checking that the speaker wires are the same at the head unit.

5.Repeat this procedure for all of the speakers.

6.Mark the power, ground, and any other wires also.
