Before you install

Automotive audio equipment installations can be challenging even to the most experienced of installation technicians. We strongly rec-
ommend that this unit should be professionally installed by a VAT registered installer (this is a requirement 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 existing 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.
