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 str gly ron ecommend

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 r ed for your parequir ticular

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 from power cables and speaker wires.

•When making connections, make certain they

are 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.

The Reference subwoofer amplifiers are

single-channel amplifiers. There are two sets of

terminals to make it easy to connect multiple

woofers. Either set of (+/–) terminals may be

used when connecting woofers.

To the right are four application diagrams to help

plan your subwoofer system installation.

NOTE: For simplicity, Figures 3 and 4 do not

show power, remote and input connections.

NOTE: Minimum impedance of each subwoofer = 4 ohms if

subwoofers are connected in parallel and 1 ohm if they

are connected in series.

NOTE: Minimum impedance of subwoofer = 2 ohms
