flag.
C. On the masking tape mark the polar-
ity of the speaker wires (+ & - ), as
well as left or right, and front or rear.

first speaker correctly by checking
that the speaker wires are the same
at the head unit.

speakers.

er wires also.
2. Mark Polarity of the Speaker Wires
Marking the polarity of the speaker wires will make it easier to connect the existing

wiring diagram is not available contact the manufacturer.
