SAFETY PRECAUTIONS
&
Important
Warnings
to
Take Note
of
BEFORE
Starting
the
Installation
& Damage Caused
By
Incorrect
Installation
or
Usage
is
NOT Covered
By
Warranty.
PLEASE Take
the
Time
to
Read
the
Installation
Notes
Carefully.
& Please make all
necessary
connections
and
terminate
any
unused
wires
so
they
do
not
short.
If
you
feel
uncomfortable
preforming
the
install
consult
a
profes-
sional
installer.
• To
avoid
any
possible
damage
to
your
vehicles
electrical
system,
be
sure
to
disconnect
the
battery
cable before
beginning
installation.
• The unit is intended for vehicles with a 12-volt battery and negative grounding.
• Before installing the unit
in
a recreational vehicle, truck, or bus, check that the
battery voltage
is
12 volts.
• Remove
the
two
transport
screws
from
the
top
of
the
unit
before
instal-
lation.
•
Be
sure to connect the negative (-) speaker leads to the negative (-) speaker
terminal. Never connect the negative(-) speaker leads to chassis ground.
• This unit is only designed for use with 4 speakers. Do not combine outputs
for use with 2 speakers. Do not ground negative speaker leads to the chassis
ground.
• Speakers connected to this unit must be high-power units with a minimum
rating
of
BOW
and impedance
of
4 to 8 ohms. Connecting speakers with output
and/or impedance values other than those noted there will result
in
damage to
the head unit and the speakers.
• Check
the
condition
off
your
speakers
carefully
-
connecting
the
unit
to
old
degraded speakers
may
result
in a
fault
which
will
damage
the
audio
IC
and
void
the
warranty.
If this unit is installed
in
a vehicle that does not have
an
ACC (accessory)
position
on
the ignition switch, the
red
lead
of
the unit should be connected to
a terminal coupled with ignition switch ON/OFF operations. If this
is
not done,
the vehicle battery may be drained when you are away from the vehicle for
several hours.
2

SAFETY PRECAUTIONS
• Secure the wiring with zip ties
or
electrical tape.
To
protect the wiring, wrap
adhesive tape around them where they lie against metal parts.
To
avoid
short-circuiting, cover all disconnected lead with insulating tape. There is a
possibility
of
short-circuiting if the leads are not insulated.
• Route and secure all wiring so it cannot touch any moving parts, such as the
gear lever and handbrake. Do not route wiring
in
places that get hot, such as
near the heater outlet. If the insulation
of
the wiring melts or gets torn, there is
a danger
of
the wiring short circuiting to the vehicle's body.
• Don't pass the yellow lead through a hole into the engine compartment to
connect to the battery. This will damage the lead's insulation and cause a very
dangerous short.
• Do not shorten any leads, if you do, the protection circuit may fail to work
when it should.
• Never feed power to other equipment by cutting the insulation
of
the power
supply lead
of
the unit and tapping into the lead. The current capacity
of
the
lead will be exceeded, causing overheating.
.
• Since a unique audio
1/C
circuit is employed, never wire so the speaker leads
are directly grounded or the left and
right-
speaker leads are common.
• When this product's source is switched ON, a control signal is turned on
through the change color to Blue/White lead. Connect to an external power
amp's system remote control
or
the car's Auto-antenna relay control terminal ·
(max. 300mA 12V DC).
• Do not block any vents or heater panels, Blocking them will cause heat to build
up and may result
in
fire.
• When replacing the fuse(s) the replacement must be
of
the same amperage
as shown on the fuse holder. Never replace a fuse with another
of
a different
value. If the fuse blows again please contact your installation company.
• Double check that all wiring and connections are correct before re-connecting
the battery and turning on the unit.
After completing the installation and before operating the unit, reconnect the
battery, then press the (RES) button with a pointed object, such as a ball-point
pen to set to unit to it's initial status. After pushing the button, wait a few sec-
onds for the red light to flash.

INSTALLATION
Tools for Installation
2 removal wrenches are supplied for taking out the old unit and replacing it with
your new Boss Audio Systems car stereo. The following tools and supplies may
also be needed for the installation:
Tools for Installation: Philips Screw-drivers /Machine Screws /Wire Stripper
/Wire Cutter /Hammer /Pencil /Electrical Tape /Electric Drill
Supplies for Installation: Machine Screws /Crimp Connectors /14 Gauge Wire for
Power Connections /14-16 Gauge Speaker Wires
The above are not supplied.
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 authorized dealer (this is a requirement
to validate the extended warranty).
IMPORTANT: Remove the two transport screws from the top fo the unit before
installing.
Remove the Old Unit from the Dashboard
1.
Remove the outer trim frame.
DIN
Front Mount
Mark Polarity of the Speaker Wires
2.
Insert the keys supplied with the
old unit into both sides
of
the unit
as shown
in
figure below until
they click. Pull to remove the old
unit from the dashboard.
DO
NOT DISCONNECT WIRES
AT
THIS TIME!
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.

WIRING DIAGRAM
Make sure You have a good chassis ground. Good ground connection will
eliminate most electrical noise problems. A good chassis ground requires a
tight connection to the vehicle's metal chassis. The area around the ground
connection should
be clean, bare metal without rust, paint, plastic, dust, or dirt
for a good ground connection.
Black Ground
Connect to vehicle body/chassis. Make sure you have a good chassis ground.
This will eliminate most electrical noise form the motor and alternator. A good
chassis ground requires a tight connection to ground. The area should
be free
from rust, paint or any form
of dirt.
Yellow Memory Backup
Connect to electrical terminal always supplied with power regardless of ignition
switch position.
Orange Remote
Connect to Auto-antenna or power amp control wire/remote connection.
