DIN Front Mount
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 VRVD630.
Consult the wiring diagram of the exist-
ing head unit before disconnecting any
wires. If a wiring diagram is not available
contact the head unit's 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.
B. Insert the keys supplied with the old unit
into both sides of the unit as shown in
figure below until they click. Pull to re-
move the old unit from the dashboard.
DO NOT DISCONNECT WIRES AT THIS TIME!
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.
