Introduction

With the

!2~~

CHAOS EXXTREME

MOSFET amplifier series,

are

introducing

thirteen

new amplifiers, all

designed

the USA. This new series

includes

three

monoblock

amps,five

2-channel, four 4-channel amplifiers

and a 5-channel amp.

All

CHAOS EXXTREME

models feature

variable low pass and high pass

crossovers and variable input gain

controls.

For further flexibility

the use

subwoofer, 0-+18dB Bass Boost

control has been included on all

amplifiers.

You

can control the

subwoofer level with the remote level

control module.

understands that amplifiers are

placed

many different kinds

installations, so we incorporated a very

flexible system

these

amplifiers

orderto help you integrate

the amp into your system regardless

the nature

Your

This

means

that

you can install

four

8 0

speakers

per

channel, when

using parallel wiring.

Increasing

the

number

woofers per

channel

low

frequencies (below

1OOHz)

produces

acoustic coupling

effect. This

acoustic

coupling

effect

increases

your

power

output

about

3dB

per

speaker,

the

equivalent

additional

per

speaker.

When

operating

the

amplifiers will increase their

output

power

approximately

50%.

The

current draw will also increase

about

the

same

amount, so be sure

you have enough current to run the

amplifiers into a 2 Q load.

If you

lack

adequate

current,

your

music

reproduction

will be

distorted.

General

precautions

Before

installing

and

using

your

new

:IO~S

amplifier,

please

be-

AUDIO

SYSTEMS

come

familiar

with

all

the

infor-

mation

contained

this

manual.

Please

keep

this

manual

safe

place

for

future

reference.

• Do not open or attempt to repair

this unit yourself. Dangerous high

voltages are present which may result

electric shock. Refer any repairs

a qualified service technician.

•

avoid risk of electronic shock or

damage to the amplifier,

not permit

any

this equipment to become

damp

or wet from water or drinks. If

this does occur, immediately unplug

the power wires and send the amplifier

to your local dealer or service center

as soon as possible.

• If there is smoke or any peculiar

odor present during use or if there is

damage

any of the component

enclosures, immediately unplug the

power wire and send the amplifier

your local dealer or service center as

soon as possible .

Installation

precautions

Before you drill or cut any holes,

investigate your earls layout very

carefully. Take special care when you

work near the gas tank, fuel lines,

hydraulic lines and electrical wiring.

Never operate the amplifier when it

unmounted. Attach all audio system

components securely

prevent

damage, especially

an accident.

User's

Manual -

Before making or breaking power

connections

your system,

disconnect the vehicle battery. Confirm

that your head unit or other equipment

turned off while connecting the input

jacks and speaker terminals.

If you need to replace the power fuse,

replace it only with a fuse identical to

that supplied with the amplifier. Using

a fuse of a different type or rating may

result

damage to your audio system

your amplifier which is not covered

by the manufacturerls warranty.

Mounting

the

amplifier

Find a suitable location

the vehicle

which to mount the amplifier.

Make sure there is sufficient air

circulation around the intended

mounting location.

Mark the location for the mounting

hole screws by positioning the amplifier

where you wish

install it. Use a

scribe or mounting screw, inserted

through each of the ampls mounting

holes,

mark the mounting surface.

If the mounting surface is carpeted,

measure the hole centers and mark

with a felt tip pen.

Drill pilot holes

the mounting

surface for the mounting screws. Place

the amplifier

position, and attach

the amplifier

the mounting surface

securely using screws.

SHOCK HAZARD! Do

not

open

the

case

this

product.

There are dangerous

voltages present within the unit. There are

no user-serviceable parts within the unit.

Connecting

the

amplifier

Before doing any wiring,

look

through

this manual and identify

the

diagrams

for

power, input and speaker

connections

for

your

particular

installation. Be sure you understand

all

the connections before you proceed.

Connect the

4. Check that the fuse holder is empty.

Then

amplifier.

If multiple amplifiers are being used

your

system, either:

• Run a separate pair

cables

from

the battery and a chassis ground point

each amplifier. Each(+) cable

must

have its

own

inline fuse.

-or-

• Run a #4 cable from

the

fuse holder

battery

a distribution

block

nearthe amplifier's location. Then

run separate cables from the amplifier

this

distribution

block

and

independent

chassis ground points.

Connect

all line inputs and

outputs

(if used) using

high-quality

cables.

Connect

all speakers, following

the

diagrams

in this manual. Be sure

observe proper polarity

avoid audio

phase problems.

Insert fuse(s) into

the

battery fuse

Recheck all

connections

before

powering
