Installation and Connections
Before installing or connecting the unit, please
read the following and pages 2 and 3 of this
manual thoroughly for proper use.
Warning
USE ONLY VEHICLES WITH A 12 VOLT NEGATIVE (–)
GROUND.
Check with your dealer if you are not sure. Failure to do
so may result in fire or electric shock.
BEFORE WIRING, DISCONNECT THE CABLE FROM
THE NEGATIVE (–) BATTERY TERMINAL.
Failure to do so may result in electric shock or injury due
to electrical shorts.
DO NOT CUT AWAY THE WIRE SHEATH AND USE
POWER FOR OTHER EQUIPMENT.
Doing so may exceed the current carrying capacity of the
wire and result in fire or electric shock.
DO NOT INSTALL IN LOCATIONS WHICH MIGHT
HINDER VEHICLE OPERATION OR CREATE
HAZARDS FOR VEHICLE OCCUPANTS.
Doing so may obstruct forward vision or hamper
movement.
DO NOT CONTACT, DAMAGE OR OBSTRUCT PIPES,
FLUID LINES OR WIRING WHEN DRILLING HOLES.
Failure to take such precautions may result in fire or cause
an accident or injuries.
DO NOT USE NUTS OR BOLTS IN THE BRAKE
SYSTEM WHEN MAKING INSTALLATION OR
GROUND CONNECTIONS.
Never use safety-related parts such as bolts or nuts in the
steering or brake systems or tanks to make wiring
installations or ground connections. Using such parts
could disable control of the vehicle and cause brake
failure, other accident or injury.
MAKE THE CORRECT CONNECTIONS.
Failure to do so may cause fire or accident to occur.
ARRANGE THE WIRING SO IT IS NOT CRIMPED OR
PINCHED.
Route the cables and wiring so as not to be crimped by
moving parts or make contact with sharp or pointed spots
which might damage the wiring. Failure to do so may
cause failure of unit or vehicle.
HAVE THE WIRING AND INSTALLATION DONE BY
EXPERTS.
The wiring and installation of this unit requires special
technical skill and experience. To ensure safety, always
contact the dealer where you purchased this unit to have
the work done.
Caution
USE SPECIFIED ACCESSORY PARTS AND INSTALL
THEM SECURELY.
Use of other than designated parts may damage this unit
internally or may not securely install the unit in place as
parts that come loose may create hazards.
DO NOT INSTALL IN LOCATIONS WITH HIGH
MOISTURE OR DUST.
A high incidence of moisture or dust that penetrates into
this unit may cause smoke or fire.
Precautions
• Be sure to disconnect the cable from the (–) battery post
before installing your CDM-7857/CDM-7854/CDE-
7853. This will reduce any chance of damage to the unit
in case of a short-circuit.
• Be sure to connect the color coded leads according to
the diagram. Incorrect connections may cause the unit
to malfunction or damage to the vehicle’s electrical
system.
• When making connections to the vehicle’s electrical
system, be aware of the factory installed components
(e.g. on-board computer). Do not tap into these leads to
provide power for this unit. When connecting the
CDM-7857/CDM-7854/CDE-7853 to the fuse box,
make sure the fuse for the intended circuit of the CDM-
7857/CDM-7854/CDE-7853 has the appropriate
amperage. Failure to do so may result in damage to the
unit and/or the vehicle. When in doubt, consult your
ALPINE dealer.
• The CDM-7857/CDM-7854/CDE-7853 uses female
RCA-type jacks for connection to other units (e.g.
amplifier) having RCA connectors. You may need an
adaptor to connect other units. If so, please contact your
authorized ALPINE dealer for assistance.
• Be sure to connect the speaker (–) leads to the speaker
(–) terminal. Never connect left and right channel
speaker cables to each other or to the vehicle body.
