Congratulations!

You

have

just

purchased

one

of

the

latest

in

a

long

line

of

exceptional

car

audio

power

amplifiers

from

Stillwater

Designs.

Your

KICKER

Impulse

was

designed

and

engineered

by

the

same

team

which

created

many

other

international

award

winning

KICKER

components

like

the

ZR,

ZX,

and

XS-Series

amps.

It

contains

a

number

of

cutting-edge

features

to

give

you

outstanding

performance

and

dependability

when

installed

in

a

properly

designed

system.

Thanks

for

buying

KICKER.

Enjoy.

KICKER

IMPULSE

AMPLIFIER

FEATURES

Two

sets

of

RCA

jacks

on

each

Kicker

Impulse

amplifier

allow

you

to

build

multiple

amplifier

systems

without

having

to

use

RCA

splitter

cords

to

distribute

the

signal.

Now

it

is

simply

a

matter

of

bringing

one

set

of

RCAs

into

the

first

amplifier,

then

using

the

output

RCA

jacks

as

a

feed

to

the next

amplifier.

Amplifiers

are

stable

at

2

Ohms

stereo

and

as

low

as

4

Ohms

in

mono.

Input

connections

are

included

for

high

and

low

level

signals

for

use

with

radios

that

have

either

RCA

or

speaker

level

outputs.

An

electronic

crossover

is

built

in

for

convenience

and

allows

you

to

select

high

pass

for

satellite

soeakers,

low

pass

for

subwoofers,

or

bypass

for

full

range

operation.

In

full

range

configuration

the

Kicker

Impulse

amplifiers

will

operate

stereo

and

mono

at

the

same

time.

|

Auto-resetting

short

circuit

and

overthermal

protection

circuits

are

incorporated

to

protect

the

amplifier

from

failure

due

to

extreme

conditions.

State

of

the

art

circuitry

including

MOSFET

power

supply

and

glass

epoxy

circuit

boards

are

used

to

ensure

many

years

of

trouble

free

operation.

Wiring

the

KICKER

Impulse

Amplifier

The

preferred

method

of

bringing

input

signal

in

to

the

amplifier

is

with

RCA

cables

from

a

quality

tape

or

CD

player.

A

high

(speaker)

level

input

signal

may

also

be

used

if

your

factory

deck

or

aftermarket

source

does

not

have

low

level

RCA

jacks.

Regardless

of

which

input

is

used

the

output

RCA

jacks

on

your

Kicker

Impulse

amplifier

will

provide

a

low

level

signal

for

multiple

amplifier

configurations.

Some

of

the

system

possibilities

are

shown

in

the

System

Diagrams

section

of

this

manual.

When

working

with

power

connections

always

hook

up

the

ground

wire

first

and

disconnect

the

ground

wire

last.

Never

make

any

wiring

changes

with

the

amplifier

powered

up.

The

chassis

mounted

fuse(s)

are

in

place

to

protect

the

circuitry

of

the

amplifier

in

the

event

of

major

trouble.

An

in-line

fuse

must

be

installed

within

18

inches

of

the

battery

to

protect

the

power

wire

used

to

supply

current

to

the

amplifier.

This

fuse

has

to

be

at

least

as

high

of

a

value

as

the

amplifier

is

supplied

with.

In-line

fuse

and

recommended

wire

size

are

as

folows:

Any

time

that

a

power

wire

goes

through

a

metal

panel

such

as

the

firewall,

or

if

there

is

any

chance

of

abrasion,

it

is

necessary

to

use

a

grommet

or

other

suitable

form

of

protection

to

avoid

shorts.

The

ground

wire

should

be

as

short

as

possible

and

attached

to

the

body

of

the

vehicle.

The

ground

point

must

be

free

from

paint

and

corrosion.

Use

the

same

size

wire

for

ground

connection

as

is

used

for

power.

Mounting

the

KICKER

Impulse

Amplifier

After

determining

an

appropriate

mounting

location

which

provides

good

air

circulation

and

access

to

the

end

panel

controls,

use

the

supplied

screws

and

washers

to

firmly

mount

the

amplifier.

The

amplifier

chassis

can

be

used

as

a

template

for

the

screw

locations.

Check

to

make

sure

that

the

mounting

screws

will

not

damage

any

components

on

the

back

side

of

the

chosen

mounting

surface.

If

a

vertical

mounting

surface

is

chosen,

it

is

recommended

that

the

heatsink

fins

run

vertically

as

shown

for

improved

cooling.

Adjustments

and

Controls

Setting

Gain

Control

The

gain

control

is

provided

for

level

matching

purposes.

The

control

does

not

give

the

amplifier

any

more

power

by

turning

it

up.

Its

purpose

is

to

adjust

the

sensitivity

of

the

amplifier

in

relation

to

the

output

level

provided

by

the

source.

Start

with

the

amp

gain

set

to

minimum

by

turning

the

control

counter-

clockwise.

Turn

the

source

level

up

until

distortion

is

barely

audible.

Then

turn

it

down

slightly.

This

will

typically

be

at

about

85%

to

95%

of

full

volume.

Raise

the

amplifier

gain

until

distortion

is

just

audible.

The

gain

is

now

set

correctly.

Check

the

level

with

cd/tape

and

tuner

to

make

sure

the

adjustment

is

correct

for

all

Sources.

Setting

KICKEQ™

Controls

The

Bass

and

Treble

controls

on

your

Impulse

Amplifier

are

provided

to

help

tune your

system

for

ideal

sound

quality.

After

the

system

is

installed

and

the

vehicle

is

put

back

together,

do

a

listening

test

with

music

that

is

typical

of

the

type

you

normally

listen

to.

Initially

set

the

tone

controls

on

the

source

unit

to

flat

and

turn

the

KICKEQ™

controls

fully

counter-clockwise.

Depending

on

your

personal

taste

and

the

speakers

used

in

the

system,

you

may

want

to

increase

the

high

or

low

frequencies

by

turning

the

KICKEQ™

controls

clockwise.

Remember

that

once

the

vehicle

is

in

motion

there

will

be

an

apparent

loss

of

bass

due

to

the

masking

effect

of

road

noise.

Do

not

attempt

to

make

adjustments

while

the

vehicle

is

in

motion.

It

is

safer

to

pull

off

the

road

to

make

changes.

Never

change

the

crossover

settings

while

the

amplifier

is

on.

A

loud

pop

will

result

which

could

destroy

speakers

or

cause

hearing

loss.

Troubleshooting

The

LED

mounted

on

the

end

panel

of

the

amplifier

lights

up

in

two

different

colors

depending

on

the

of

the
