Automotive audio equipment installations can be challenging at times, even to the most 
experienced of installation technicians. If you are not confi dent working with electrical

nents of your vehicle, please call our toll-free help line 1-800-445-1797 and our in-house 
technical service team will answer your installation questions. Contact the vehicle's

sionally installed.

DO NOT DISCONNECT WIRES AT THIS TIME!

A. Remove the outer trim frame.

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.
