Before you install

Automotive audio equipment installations can be challenging even to the most 
experienced  of  installation  technicians.  We  strongly  recommend  that  this  unit 
should be professionally installed by a VAT registered installer (this is a require-
ment to validate the warranty).
IMPORTANT: Remove the two transport screws from the top fo the unit before 
installing.  

Mark Polarity of the Speaker Wires

Marking  the  polarity  of  the  speaker  wirers  will  make  it  easier  to  connect  the 
existing speakers to your car radio. Consult wiring diagram of existing head unit 
before disconnecting any wires. If you are not positive of the polarity of the exist-
ing 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 flag.
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 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.
