instructions

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.

INTRODUCTION

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 of the audio system and other electricalf

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 an holes ory

installing an screws. Remember that they

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, mak

e cer

tain 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.

The Reference amplifiers are capable of

delivering high power levels, and require a

reliable connection to the vehicle’s electrical

system in order to perform optimally. See

Figure 1 for connection location. Please

adhere to the following instructions carefully.

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 below to determine minimum wire-gauge

size. Sand away any paint from this location; 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.

WIRE-GAUGE CHART

Amplifier Maximum Minimum

Model Current Draw Wire Gauge

7521a 34A #8 AWG

7541a 85A #8 AWG

5761a 87A #8 AWG

311a 40A #8 AWG

611a 69A #6 AWG

1211a 115A #4 AWG

These recommendations assume 7' – 10' wire

runs. If your installation differs markedly, you

will need to adjust the wire gauge accordingly.

SPEAKER CONNECTIONS

Refer to the application guides on the pages

that follow. Speaker connections should be

made using a minimum of 16-gauge wire.

HIGH-LEVEL INPUT CONNECTIONS

The 7521a, 7541a and 5761a amplifiers are

equipped with speaker-level inputs that allow

you to add an amplifier to head units that do

not have RCA line outputs. The speaker outputs

for the source unit should be connected to the

amplifier using the supplied connector (square

four-wire plug). Remember to check for proper

polarity. The 311a, 611a and 1211a amplifiers

are not equipped with high-level inputs.

NOTE: When using the low-level or high-level

inputs, the AUX outputs can be used to pass a

full-range line-level signal to another amplifier.
