CAUTION
Caution on connection terminals/parts
Keep electrically conductive objects away from the unit's terminals/parts (power
terminals,
fuses, speaker output terminals, RCA connectors, etc.). Doing so prevents a possible short
circuit and damage
to
the unit.
Use appropriate electrical
source.
The person installing this
will
choose the appropriate
electrical
source.
To prevent external noise from entering the audio system.
Locate the unit and route the leads at least 10 cm (3-15/16") away from the car
harness.
Keep the battery power leads as far away from other leads as possible.
Connect the ground lead securely to a bare metal spot
(remove
any paint or grease if necessary) of the car
chassis.
Your Alpine dealer knows best about noise prevention
measures so consult your dealer for further
information.

®
Input Signal Leads
There are two
options:
a) RCA Input Jacks
Connect these jacks to the line out leads on your head
unit,

then connect the correct corresponding speaker outputs from the
head unit directly to these twisted pair
wires.
For the

connecting the Remote Turn-On Lead is not
required due to the
"REMOTE

In such a case,
connect the Remote Turn-On Lead to an incoming power supply wire (accessory power) in
the ACC
position.
@
Ground Lead (Black)
Connect this lead securely to
a
clean, bare metal spot on
the vehicle's chassis. Verify this point to be a true ground by checking for continuity between
that point and the negative (-) terminal of the vehicle's battery. Ground all your audio
components to the same point on the chassis to prevent ground loops.
®
Battery Lead (Yellow)
Connect battery lead directly to BATT +
Be sure to add a 20A fuse (sold separately) as close as possible to the battery's (+) terminal.
