FUNCTIONS

1.

Speakers

-

Connect

speakers/subwoofers

to

these

terminals.

Be

sure

to

check wire for proper

polarity.

Never

connect

the

speaker

cables

to

the

chassis

ground.

2.

+BAIT(+

12

Volt

Power)-

Connect

this terminal through a

FUSE

or

CIRCUIT

BREAKER

to

the

positive

terminal

of

the

vehicle battery

or

the

positive

terminal

of

an

isolated

audio

system

battery.

WARNING:

Always protect this power

cable

by

installing a

fuse

or

circuit breaker

of

the

appropriate

gauge

within

18

inches

(45cm)

of

the

battery terminal connection.

3.

Remote-

This

terminal turns

on

the

amplifier

when

(+)

12

volt

is

applied

to

it.

Connect

it

to

the

remote

turn

on

lead

of

the

head

unit

or

signal

source.

4.

GND-

Connect

this

cable

directly

to

the

frame

of

the

vehicle.

Make

sure

the

metal

frame

has

been

stripped

of

all

paint

down

to

the

bare

metal.

Use

the

shortest distance

possible.

It

is

always

a

good

idea

to

replace

the

factory

ground

at

this

time

with a

cable

equal

or

larger

than

the

new

amplifier power

cable.

CAUTION:

Do

not

connect this terminal directly

to

the

vehicle battery

ground

terminal

or

any

other factory

ground

points.

5.

RCA

Input Jacks-

These

RCA

input jacks

are

for

use

with source

units

that

have

RCA

outputs.

A

source

unit with a

minimum

level

of

200mV

is

required

for proper operation.

The

use

of

high

quality twisted pair

cables

is

recommended

to

decrease

the

possibility

of

radiated

noise

entering

the

system.

6.

Level

Control

-The

Level,

or

Gain

control will

match

the

amplifier's sensitivity

to

the

source

units

signal

voltage.

The

operating

range

is

5V

to

200mV.

NOTE:

This

is

NOT

a

volume

control.

7.

Low

Pass

Filter

Control

(Mono

Block)-

This

control

is

used

to

select

the

desired

low

pass

x-over

frequency.

The

frequency

can

be

adjusted

from

40Hz

to

250Hz

for

all

bass

mono

models.

8.

Subsonic

Filter

Control

(Mono

Block)

-This control

can

filter out

unwanted

low frequency

from

10Hz

(OFF)

to

50Hz.

This

function

should

only

be

used

with

vented

enclosures.

9.

Bass

Boost

Level

(Mono

Block)

-This

can

boost

bass

level

up

to

18dB.

The

boost

frequency

is

centered

at

45Hz.

2

MTX.COM

10.

High

Pass

Filter

(Full

Range)-

This

controls

the

frequencies

played

for

the

front

and

rear

channels.

Low

frequencies

can

be

cut off

from

40Hz

to

250Hz.

11.

X-Over

Mode

and

Frequency

Control

(Full

Range)-

These

controls allow control

over

the

frequencies

played

for

the

rear

channels.

There

is

an

option

for

Low

Pass,

Full

Range,

or

High

Pass.

In

LP

or

HP

mode,

the

crossover frequency

can

be

tuned

from

40Hz

to

250Hz.

12.

Power

Indicator-

This

Blue

LED

will light

up

when

the

amplifier

is

working

properly.

13.

Protection Indicator-

This

Red

LED

will light

up

and

flash

ifthere

is

afault

presented

to

the

amplifier.

Please

disconnect

the

amplifier

and

resolve

the

fault

before

reconnecting

the

amplifier.

14.

Remote

Turn

On-

This

unit features

auto

turn

on

technology allowing installation

via

high

level

input without

the

use

of

a

remote

wire. If

using

afactory

or

aftermarket

radio

that

does

not

include

RCA

outputs,

the

amplifier

can

be

connected

to

the

source

unit

via

high

level

speaker

wire

via

the

high

level

input.

The

Remote

Turn

On

switch

when

placed

in

the

"Auto"

position

will

allow

the

unit

to

turn itself

on

without

the

need

to

connect a

remote

wire.

In

the

"Ext"

position

the

unit will

require

a

remote

wire connection

to

turn

on.

15.

Amplifier

Strapping

-Two

units

can

be

linked

together

to

achieve

a

strapped

2

Ohm

output.

One

unit

must

have

the

switch

in

the

Master

position

and

the

other

must

be

in

the

Slave

position.

Connect

a

single

RCA

interconnect

from

the

Input/Output

of

the

Master amplifier

to

the

Input/

Output

of

the

Slave

amplifier.

Connect

the

negative

speaker

output terminal

from

the

Master

to

the

negative

speaker

output terminal

on

the

Slave

amplifier.

Connect

the

positive

speaker

output

terminal

from

the

Master amplifier

to

the

positive

speaker

input terminal

on

the

subwoofer

or

terminal

cup

and

the

positive

speaker

output terminal

from

the

Slave

amplifier

to

the

negative

speaker

inputterminal

on

the

subwoofer

or

terminal

cup.

Use

caution

not

to

connect

the

negative

speaker

output terminal

on

either amplifier

to

the

ground

or

chassis.

for amplifier wiring

diagrams.

INSTALLATION

AND

MOUNTING

MTX

recommends

your

new

XTHUNDER

amplifier

be

installed

by

a

12

volt installation specialist.

Any

deviation

from

specified installation instructions

can

cause

serious

damage

to

the

amplifier,

speakers

and/or vehicle's electrical

system.

Damage

caused

from

improper installation

is

NOT

covered

under

warranty.

Please

verify

all

connections prior

to

system

turn

on.

1.

Disconnect

the

vehicle's

negative

battery

cable.

2.

Determine

the

mounting

place

for

your

MTX

amplifier.

Keep

in

mind

there

should

be

sufficient

air

flow for proper

cooling.

Mark

the

mounting

holes

from

the

amplifier

to

be

drilled.

Before

drilling

make

sure

all

vehicle wires,

gas

lines,

brake

lines

and

gas

tank

are

clear

and

will

not

interfere with installation. Drill

the

desired

holes

and

mount

the

MTX

amplifier.

3.

Install apositive(+) power

cable

from

the

vehicle's battery through

the

firewall

using

a

grommet

or

firewall

bushing

to

avoid

cable

damage

from

sharp

edges

of

the

firewall.

Run

the

cable

through

the

interior

of

the

vehicle

and

connect it

to

the

amplifier's (+BATI) terminal.

Do

not

connect

to

the

battery

at

this

time.

NOTE:

Use

only

proper

gauge

wire for

both

positive

and

negative

connections.

4.

Install acircuit breaker

or

fuse

within

18

inches

of

the

battery.

This

effectively lowers

the

risk

of

severe

damage

to

you

or

your vehicle

in

case

of

ashort circuit

or

accident.

Make

sure

the

circuit breaker

is

switched

Off

or

the

fuse

is

taken

out

of

the

fuse

holder untill

all

connections

are

made.

Now

connect your

positive

power

cable

to

the

positive

battery terminal

of

the

battery.

5.

Grounding

-

Locate

a

proper

ground

point

on

the

vehicle's

chassis

and

remove

all

paint,

dirt

or

debris

to

reveal

a

bare

metal

surface.

Attach

the

ground

wire

to

that contact

point.

Connect

the

opposite

end

of

the

ground

wire

to

the

(GND)

terminal

on

the

MTX

amplifier.

6.

Connect

a

Remote

Turn-On

wire

from

the

source

unit

to

the

MTX

amplifier's

(REM)

terminal. If

the

source

unit

does

not

have

adedicated

Remote

Turn-On

lead,

you

may

connect

to

the

source

unit's

Power

Antenna

lead.

7.

Supply

the

signal

to

your

MTX

amplifier

by

connecting

the

signal

cables

using

high

quality

RCA

to

the

corresponding

outputs

at

the

source

unit

and

inputs

of

the

amplifier.

8.

Connect

your

speakers

to

your

MTX

amplifier's

speaker

terminals

using

the

correct

gauge

speaker

wire.

Your

MTX

amp

can

drive

a

2Q

(XTHUNDER125.4

&

XTHUNDER800.5)

or

1Q

(XTHUNDER1200.1

&XTHUNDER1500.1)

minimum

load

for

optimum

power.

9.

Double

check

all

steps,

in

particular, wiring

and

component

connections.

Once

verified, reconnect

the

vehicle's

negative

battery

cable,

turn

the

circuit

breaker

On

or

place

the

fuse

in

the

fuse

holder.

NOTE:

Gain

Levels

on

the

amplifier

should

be

turned

all

the

way

down

(counter clockwise)

before

proceeding

with

adjustments.

MTX.COM
