Choose a mounting location in the trunk or
cargo area where the amplifier will not be dam-
aged by shifting cargo. Amplifier cooling is
essential for proper amplifier operation. If the
amplifier is to be installed in an enclosed space,
make sure there is sufficient air circulation for
the amplifier to cool itself.
When mounting the amplifier under a seat,
ensure that it is clear of all moving seat parts
and does not affect the seat adjustments. Mount
the amplifier so it is not damaged by the feet
of backseat passengers. Make sure that the
amplifier is mounted securely using nuts and
bolts or the supplied mounting screws.
Mount the amplifier so that it remains
dry – never mount an amplifier outside
the vehicle or in the engine compartment.
The amplifier’s trim panel must be removed to
gain access to the mounting tabs. To remove the
panel, grasp the ends (indicated by arrows) and
pull upward gently. To replace the panel, align
the fasteners and press downward gently.

INTRODUCTION

THANK YOU for purchasing an Infinity
®
Reference
Series amplifier. In order that we may better
serve you should you require warranty service
for your new amplifier, please retain your origi-
nal purchase receipt and read the enclosed war-
ranty information card.
WARNING!
Playing loud music in an automobile can hinder
your ability to hear traffic and permanently
damage your hearing. We recommend listening
at low or moderate levels while driving your
car. Infinity accepts no liability for hearing loss,
bodily injury or property damage resulting from
the use or misuse of this product.
IMPORTANT
To get the best performance from your Reference
Series amplifiers, we strongly recommend
that installation be entrusted to a qualified
professional. Although these instructions explain
how to install Reference amplifiers in a general
sense, they do not show specific installation
methods that may be required for your particular
vehicle. If you do not have the necessary tools or
experience, do not attempt the installation your-
self. Instead, please ask your authorized Infinity
car audio dealer about professional installation.
INSTALLATION WARNINGS AND TIPS
Always wear protective eyewear when using
tools.
Turn off the audio system and other electrical
devices before you start. Disconnect the (–)
negative lead from your vehicle’s battery.
Check clearances on both sides of a planned
mounting surface before drilling any holes or
installing any screws. Remember that the
screws can extend behind the surface.
At the installation sites, locate and make a note of
all fuel lines, hydraulic brake lines, vacuum lines
and electrical wiring. Use extreme caution when
cutting or drilling in and around these areas.
Before drilling or cutting holes, use a utility
knife to remove unwanted fabric or vinyl to
keep material from snagging in the drill bit.
When routing cables, keep input-signal cables
away fr
om power cables and speaker wir
es.
When making connections, make cer
tain they
ar
e secure and properly insulated.
If the amplifier’
s fuse must be replaced, use
only the same type and rating as that of the
original. Do not substitute another kind.
GROUND CONNECTION
Connect the amplifier’s ground (GND) terminal
to a solid point on the vehicle’s metal chassis,
as close to the amplifier as possible. Refer to the
chart to the right to determine minimum wire-
gauge size. Sand away any paint from this loca-
tion; use a star-type-lock washer to secure the
connection.
POWER CONNECTION
Connect a wire (see chart at right for appropriate
gauge) directly to the vehicle’s positive battery
terminal, and install an appropriate fuse holder
within 18" of the battery terminal. Do not
install the fuse at this time. Route the wire to
the amplifier’s location, and connect it to the
amplifier’s positive (+12V) terminal. Be sure to
use appropriate grommets whenever routing
wires through the firewall or other sheet metal.
Failure to adequately protect the positive wire
from potential damage may result in a vehicle
fire. When you are done routing and connecting
this wire to the battery and to the amplifier,
you may install the fuse at the battery. The
fuse value should be selected based on total
amplifier-current draw; see chart at right.
REMOTE CONNECTION
Connect the amplifier’s remote (REMOTE)
terminal to the source unit’s remote turn-on
lead using a minimum of 18-gauge wire. If your
source unit does not have a remote turn-on
connection, connect the amplifier’s (REMOTE)
terminal to the vehicle’s accessory circuit.
