or

a

fatal

electrical

shock.

If

liquids

get

into

the

amplifier,

immediately

dis-

connect

the

power

to

the

amplifier.

•

Do

not

expose

the

amplifier

to

high

temperatures,

strong

vibrations

or

heavy

loads.

• Keep open flames away

from

the

amplifier.

•

Call

1-800-955-9094

if

you

have

questions

about

how

the

equipment

operates

or

about

how

to

•

Observe

the

safety

and

operating

instructions

of

this

amplifier

and

any

other

devices

connected

to

the

amplifier.

•

Exposure

to

are

in

doubt

when

selecting

a

place

for

instaUatiori;

consult

your

local

car

dealership.

Since

the

amplifier

generates

heat,

be

sure

to

install

in

a

heat-

resistant

location.

There

must

also

be

an

open

area

of

1/4"

around

the

amplifier's

housing

for

adequate

ventilation.

Air

circulation

may

not

be

obstructed

by

objects

such

as

magazines,

blankets,

maps,

etc.

Before

drilling

any

holes

in

your

car,

make

sure

that

electric

cables,

brake

lines,

fuel

tank

or

similar

systems

will

not

be

damaged.

When

installing

the

car

audio

compo-

nents,

consider

the

danger

of

parts

breaking

loose

during

an

accident.

Make

sure

each

component

of

your

sys-

6

tern

is

fastened

tightly,

and

located

at

a

place

where

it

cannot

become a

risk

for

passengers

in

the

event

of

an

accident.

Select

a

suitable

position

for

mounting

the

amplifier.

A

suitable

place

for

mounting

has

the

following

features:

•

dry

•

as

free

from

dust

as

possible

•

minimal

vibration

• good

air

circulation

•

heat-resistant

environment

'

' ' • Mark

the

holes

for

the

screws

at

the

place

of

installation.

The

simplest

way

to

do

this

is

place

the

amp

where

you

want

it

and

use

it

as

a

pattern.

•

Drill

the

holes

for

the

fastening

screws.

•

Secure

the

amplifier

with

sheet

metal

screws.

9094 if you

have

questions during setup.

Use

heavy-gauge

cable

for

connecting

the

power

supply

and

the

ground

of

the

amplifier.

The

gauge

of

the

cable

depends

on

the

power

requirements

of

the

components

connected.

If

the

gauge

is

too

light,

the

cable

could

burn.

Moreover,

the

increased

resis-

tance

can

lead

to

unnecessary

power

losses.

An

additional

fuse

in

the

amp's

posi-

tive

connection

is

necessary

(fuse

and

fuse

holder

not

included.)

The

fuse

should

be

installed

close

to

the

battery.

In

case

of

short

circuit

(e.g.

if

the

connection

cable

is

worn

through),

this

fuse

disconnects

the

positive

lead

and

thus

avoids

dam-

age

to

the

battery

and

prevents

the

supply

cable

from

burning.

The amperage

rating

of

the

fuse

depends

on

the

power

consumption

of

the

connected

devices

of

the

car

audio

system.

In

order

to

reduce

interference

or

noise

in

the

system,

the

amplifier

should

be

directly

powered

by

the

car

battery.

Do

not

supply

other

electric

loads,

such

as

the

cooling

fan,

windshield

washer

etc.,

via

the

same

cable

as

the

amplifier.

POWER

CONNECTIONS

Connect

the

"+12V"

connector

of

the

power

supply's

terminal

directly

to

the

car

battery's

positive

terminal

Connect

the

"REMOTE"

or

"REM"

connec-

tor

to

the

terminal

on

the

power

sup-

ply,

to

the

remote

control

connector,

or

to

the

antenna

control

output

of

the

car's

radio.

The

amplifier

will

be

switched

on

via

this

input

when +12V

current

is

applied.

Almost

all

car

radios

have

an

output

which

provides

a

+12V

current

when

the

radio

is

turned

on.

Connect

the

"GND"

connector

of

the

power

supply

to

the

car

body.

Note:

Since

electrical

conductivity

is

limited

CONNECTING

THE

INPUTS

All

MODELS

These

amplifiers

use

RCA

inputs

for

connection

to

your

car

stereo's

preamp

outputs.

Car

radios

with

RCA

outputs

can

be

directly

con-

nected

to

the

input

sockets.

If

your

car

radio

only

has

speaker

outputs,

you

can

use

an

optional

adapter

or

line

output

converter

to

make

the

connection.

When

connecting the RCA inputs,

use

only shielded RCA cables

suitable for

this

purpose. The

use

of

any

other type

of

cable

may

cause interference.

CONNECTING

THE

SPEAKER

OUTPUTS

Depending

on

your

model,

Sound

Ordnance

amplifiers

have

outputs

for

four

speakers,

two

speakers,

or

one

speaker.

You

can

bridge

the

2-channel

ampli-

fier

to

mo

no

mode

to

power a

single

speaker,

or

the

4-channel

amp

to

2-channel

mode

to

power a

pair

of

speakers.

You'll

get

more power

by

bridging

the

amp.

Strip

the

insulation

from

the

cables

on

the

ends.

Make

sure

that

there

are

no

sharp

edges

which

may

damage

the

cables.

Only

use

speakers

whose power

handling

matches

the

amp's

output

(see

Technical

Specifications).

Always

co

nne

ct

the

speakers

with

the

correct

polarity.

10

Speaker

wires

are

usually

coded.

Some

loudspeaker

manufacturers

indicate

the

(+)

wire

by

means

of

an

additional

color

stripe,

others

use

a

corrugated

cable

for

the

(+)

terminal

and

a

smooth

one

for

the

(-)

terminal.

Sound

Ordnance

amplifiers

have

been

designed

for

a

loudspeaker

imped-

ance

of

at

least

2

ohms

(in

standard

operating

mode)

or

4 ohms

(in

bridged

mode).

Never

connect

speakers

with

a

lower

impedance.

Depending

on

the

model

and

mode

of

operation,

connect

the

loudspeaker

outputs

according

to

the

following

schemes.

Observe

the

minimum

imped-

ance

given

for

the

corresponding

mode

of

operation
