PROTECT YOUR HEARING!

We value you as a long-term customer. For

that

reason, we urge you to practice

restraint

in

the

operation

of

this

product

so as

not

to

damage

your

hearing

and

that

of

others

Studies have shown

that

continuous exposure to

high

sound

pressure levels

can

lead to

permanent

(irreparable)

hearing

loss. This

and

all

other

high-power amplifiers are capable

of

producing

such

high

sound

pressure levels when

connected

to a speaker system. Please limit

your

continuous

exposure to

high

volume levels.

While

driving, operate

your

audio system

in

a

manner

that

still allows you to

hear

necessary

noises to operate

your

vehicle safely (horns,

sirens, etc.).

In

the

event

that

your

amplifier requires

service

or

is ever stolen, you will need to have

a record

of

the

XD800/8v2 Owner's Manual

PLANNING YOUR INSTALLATION

It

is

important

that

you take

the

time

to read

this

manual

and

that

you

plan

out

your

installation carefully.

The

following are some

considerations

that

you

must

take into account

when

planning

your

installation.

Cooling Efficiency

Considerations:

The

outer

shell

of

your

JL

Audio amplifier

is

designed to remove heat from

the

amplifier

circuitry. For

optimum

cooling performance, this

outer shell should be exposed to as large a volume

of

air

as possible. Enclosing

the

amplifier in a

small, poorlyventilated

chamber

can

lead to

excessive heat build-up

and

degraded

performance.

If

an

installation calls for

an

enclosure

around

the

amplifier, we

recommend

that

this enclosure be ventilated

with

the

aid

of

a fan.

In

normal

applications, fan-cooling

is

not

necessary.

OIMPORTANTI

Stupid Mistakes

to

Avoid

Mounting

the

amplifier

upside

down

is

strongly

discouraged.

If

mounting

the a1nplifier

under

a seat,

make sure there

is

at least 1 inch (2.5 em)

of

space above the amplifier's outer shell to

permit

proper

cooling.

• Check before drilling any holes

in

your vehicle

to make sure

that

you will

not

be drilling

through

a gas tank, brake line, wiring harness

or

other

vital vehicle system.

Safety Considerations:

•

Do

not

run

system wiring outside

or

underneath

the vehicle. This

is

an

extremely dangerous

practice which

can

result

in

severe damage to

your

vehicle

and

person.

Your amplifier needs to be installed in a dry,

well-ventilated

environment

and

in a

manner

which does

not

interfere with your vehicle's safety

equipment (air bags, seat belt systems,

ABS

brake

systems, etc.).

You

should also take the

time

to

securely

mount

the amplifier so

that

it does

not

come loose in the event

of

a collision

or

a

sudden

jolt to

the

vehicle.

• Protect all system wires from

sharp

metal

edges

and

wear by carefully routing them,

tying

them

down

and

using

grommets

and

loom where appropriate.

• Do not

mount

the amplifier in

the

engine

compartment,

under

the vehicle,

on

the

roof

or

in any

other

area

that

will expose the

amplifier circuitry to the elements.

PRODUCT DESCRIPTION

The

JL

Audio XD800/8v2

is

an

eight-channel,

full-range audio amplifier utilizing

JL

Audio

NexD'M

ultra-high speed switching technology to

deliver

outstanding

fidelity

and

efficiency.

The

XD800/8v2

can

be operated with a wide

variety

of

source units

and

system configurations.

TYPICAL INSTALLATION SEQUENCE

The

following represents the sequence

for a typical amplifier installation, using

an

aftermarket

source

unit

or

OEM

Interface

processor (like

the

CleanSweep CL441dsp).

Additional steps

and

different procedures

may

be required

in

some applications.

If

you have

any

questions, please contact your

authorized

JL

Audio dealer for assistance.

1)

Disconnect

the

negative

battery

post

connection

and

secure

the

disconnected cable

to prevent accidental re-connection

during

installation.

This

step is

not

optional.

2) Run 4 AWG power wire from the

battery

location to

the

amplifier

mounting

location,

taking

care to route it

in

such a way

that

it

will

not

be

damaged

and

will not interfere

with

vehicle operation. Use 2 AWG

or

larger

power wire

and

a power distribution block

if

additional amplifiers are being installed with

the

XD800/8v2.

3)

Connect

power wire to

the

positive

battery

post. Fuse

the

wire

with

an

appropriate fuse

block (and connectors)

within

18

inches

(45

em) wire

length

of

the

positive

battery

post.

This fuse is essential

to

protect the vehicle.

Do

not

install the fuse until the powerwire

has

been

securelyconnected to the amplifier.

4) Run signal cables

and

remote

turn-on

wire

from

the

source

unit

to

the

final amplifier

mounting

location.

5)

Run

speaker cables from

the

speaker systems

to

the

amplifier

mounting

location.

6)

Find

a good, solid metal

grounding

point

close

to

the amplifier

and

connect

the

negative power wire to it using appropriate

hardware

(use

of

the

JL

Audio ECS

master

ground

lug, XB-MGLU is recommended).

Use 4 AWG wire, no longer

than

36 inches

(90 em) from

the

amplifier to

the

ground

connection

point.

In

some vehicles, it

may

be

necessary to upgrade

the

battery

ground

wire.

(See page 5 for

important

notice).

JL

Audio

XD800/8v2 Owner's Manual

7) Securely

mount

the an1plifier.

8)

Connect

the

positive

and

negative power

wires to the amplifier. A fuse near

the amplifier

is

not necessary

if

the

XD800/8v2

is

the only device being

run

from

the

fused

main

power wire.

If

the

fused

main

power wire is shared

by

the

XD800/8v2

and

other

amplifiers

or

devices, fuse each amplifier/device

within

12

inches

(30

em)

of

wire length,

via a fused distribution block

or

multiple

individual fuse blocks/on-board fuses.

9)

Connect

the

remote

turn-on

wire

to

the

amplifier.

10)

Connect

the

input

cables to

the

amplifier.

11)

Connect

the

speaker cables to

the

amplifier.

12) Carefully review

the

amplifier's control

settings to make sure

that

they are set

according to the needs

of

the system.

13) Install the power wire fuse (80A for a

single XD800/8v2)

and

reconnect

the

negative

battery

post

terminal. Install

the

fuse (80A)

near

the

amplifier (if applicable).

14)

Turn

on

the

source

unit

at a low level

to double-check that

the

amplifier is

configured correctly. Resist

the

temptation

to

crank

it up until you have verified

the

control settings.

15) Make necessary adjustments to

the

input

sensitivity controls to

obtain

the

right

overall

output

and

the

desired balance

in the system. See

Appendix

A (page

14)

for

the

recommended

input

sensitivity

setting

method.

16) Enjoy

the

fruits

of

your labor with

your

favorite music.

POWER CONNECTIONS

Before installing the arnplifier, disconnect the

negative (ground) wire from the vehicle's battery.

This will prevent accidental dan1age to the system,

the vehicle

and

your body

during

installation.

Ground

Remote

\ I \

/l

XDBOO/Bve

The

XD800/8v2's

"+

12 VDC"

and

"Ground"

connections are designed to accept 4 AWG

power wire. 4 AWG is the required wire

size

for

this

amplifier.

If

you are installing the XD800/8v2 with

other

amplifiers

and

wish to use a single

main

power

wire, use 2 AWG

or

1/0 AWG

main

power wire

(depending

on

the overall

current

demands

of

all

the

amplifiers

in

the system). This 2 AWG

or

1/0 A

WG

power wire should terminate into a

fused distribution block

mounted

as close to

the

amplifiers as possible (within

12

inches/

30cnl

of

wire length).

The

fused

output

of

the

distribution

block will connect to the

XD800/8v2

with

4 AWG power wire.

JL

Audio

ECS fused distribution blocks are

recommended

(XD-FDBU-2

and

XD-FDBU-4)

Note: Smaller AWG

numbers

mean

bigger

wire

and

vice-versa (1/0 AWG is the largest, 2

AWG is smaller,

then

4 AWG,

then

8 AWG, etc.).

To

connect

the

power wires to

the

amplifier,

first

back

out

the set screw

on

the

top

of

the

tenninal

block, using

the

supplied 2.5

mm

hex

wrench. Strip 1/2 inch

(12

mtn)

of

insulation from

the

end

of

each wire

and

insert

the

bare wire into

the

terminal

block, seating it firmly so

that

no

bare wire

is

exposed.

While

holding the wire

in

place, tighten

the

set screw firmly,

taking

care

not

to strip

the

head

of

the

screw.

The

ground

connection

should

be

made

using

4 AWG wire

and

should

be kept as

short

as possible, while accessing a solid

piece

of

sheet metal in

the

vehicle.

The

--

-

--

------

--

- -

---

--

-

-------

SL

rface

of

the

sheet

metal

should

be

sanded

at

t11e

contact

point

to create a clean, metal-

to-nletal

connection

between

the

chassis

and

the

termination

of

the

ground

wire.

For

optimal

grounding,

we

recommend

the

use

of

a

JL

Audio ECS

master

ground

lug

(XB-MGLU). Alternatively, a sheet

metal

screw

or

bolt

can

be

used

with

a

star

washer.

Any wires

run

through

metal barriers (such

as firewalls),

must

be protected

with

a high

quality

rubber

grommet

to prevent damage to the

insulation

of

the

wire. Failure to do so

n1ay

result

in a dangerous

short

circuit.

OIMPORTANTI

Manyvehicles employ sntall (10 AWG -

6 AWG) wire

to

ground

the battery

to

the

vehicle chassis

and

to

connect

the

alternator's

positive

connection

to

the battery. To prevent

voltage drops, these wires

should

be upgraded

to 4 AWG when

installing

amplifier

systems

with

main

fuse ratings above 60A.

FUSE REQUIREMENTS

It

is

absolutely vital

that

the

main

power

wire(s) to

the

amplifier(s) in

the

system be

fused

within

18

inches

(45

em)

of

the

positive

battery

post connection.

The

fuse value at each

power wire should be

high

enough

for all

of

the

equiprnent being

run

from

that

power wire.

If

only

the

XD800/8v2

is

being

run

from

that

power

wire,

we

recommend

a 80A fuse be used.

If

fusing

the

amplifier

near

its power

connections (when more

than

one

amp

is being

run

from

the

main

power wire), use a 80A fuse.

MAXI'M

(big plastic-body) fuses

are recommended.

TURN-ON OPTIONS

The

XD800/8v2

can

be switched

on

and

off

using

one

of

three

methods,

determined

by

the

position

of

the

amplifier's "Turn-On Mode"

switch. Please read these options

Q(c:)(c:)~R)

+12 V Remote Turn-On: This

is

the

preferred

method

for

turning

the

amplifier on/off.

The

amplifier will

turn

on

when

+

12

V is present at

its "Remote"

input

and

turn

off

when

+

12

V is

switched off. This +12V remote

turn-on

signal is

typically controlled by a source unit's remote

turn-on

wire.

The

XD800/8v2's "Remote"

turn-

on

connector

will accept

18

AWG-

12

AWG

wire. To

connect

the

remote

turn-on

wire to

the

amplifier, first back

out

the

set screw

on

the

top

of

the

terminal

block, using

the

supplied 2.5

mm

hex wrench. Strip 1/2 inch (12mm)

of

wire

and

insert

the

bare wire into

the

terminal

block,

seating it firmly so

that

no

bare wire is exposed.

While

holding

the

wire

in

the

terminal,

tighten

the

set screw firmly,

taking

care

not

to

strip

the

head

of

the

screw

and

making

sure

that

the

wire

is firmly

gripped

by

the

set screw.

If

a source unit does not have a dedicated

remote turn-on output, consider

one

of

the

following alternative turn-on options:

These

methods

are useful when a conventional

+

12

V remote

turn-on

signal

is

not

available

in

a

system. These allow

you

to operate

the

amplifier

without

having to locate a remote

turn-on

lead at

the

source unit, which

can

be very useful

when

interfacing

the

amplifier

with

OEM

(factory)

audio systems

that

do

not

use conventional +12 V

turn-on

leads.

I

JL

Audio-

XD800/8v2 Owner's Manual

Depending

on

the characteristics

of

the

audio

signal, one

of

the

following

methods

may work

better

than

the other. We recon1mend

trying

DC

Offset-Sensing first as it does not require a long

delay to

turn

the system

off

after

the

signal

is

shut off.

DC Offset-Sensing:

The

amplifier will

turn

on

and

offby detecting the presence

of

a very sin

all

DC

signal (offset)

that

is

typical in

the

audio

output

of

most

OE!vl

(factory) source units

and

amplifiers.

The

amplifier will

turn

on

and

off

in

reaction to the presence

or

absence

of

this

DC

Offset.

The

sensitivity

of

this

circuit

is

designed

for high-level (speaker level) signals,

not

for low-

level (preamp level) signals. The circuit n1onitors

the signal at the

Channel

1 input only.

Signal-Sensing:

The

amplifier will

turn

on

and

off

by detecting

the

presence

of

a full-range

audio signal at its

Channel

1 input. After several

minutes

of

no signal,

the

amplifier will shut off.

The

sensitivity

of

this circuit

is

designed for

high-level (speaker level) signals, not for low-level

(preamp level) signals.

The

circuit

is

tuned

to

react to signals at rnid-range frequencies. This

prevents false switching

from

signals created by

moving loudspeakers

that

are

in

parallel

with

the

XD800/8v2 Owner's Manual

FILTER CONTROLS

Most speakers are

not

designed to reproduce

the

full range

of

frequencies audible by

the

human

ear. For this reason,

most

speaker systems are

comprised

of

n1ultiple speakers, each dedicated

to reproducing a specific frequency range. Filters

are used to select which frequency range

is

sent

to each section

of

a speaker systen1.

The

division

of

frequency ranges to different speakers

can

be

done with passive filters (coils

and/or

capacitors

between

the

amplifier

outputs

and

the

speakers),

which are acceptable

and

commonly

used

for filtering between mid-range speakers

and

tweeters. Filtering between subwoofer systems

and

satellite speaker systems is best

done

with

active filters, which cut

off

frequency content at

the

input

to

the

amplifier. Active filters are

more

stable

than

passive filters

and

do

not

introduce

extraneous resistance, which

can

degrade

subwoofer performance.

The active filter built into each

channel

section

of

the XD800/8v2 can be used to eliminate

potentially

harmful

and/or

undesired

frequencies

from

making

their way

through

the

amplifier

sections to the speaker(s). This serves to improve

tonal balance

and

to avoid distortion

and

possible

speaker failure. Correct use

of

these filters

can

substantially increase the longevity

and

fidelity

of

your

audio system.

"Filter Mode" Control:

The

XD800/8v2

employs a 12dB

per

octave filter for each

pair

of

channels. Each

of

these filters

can

be

configured independently into

one

of

two filter

types

or

defeated completely by way

of

the

three-position "Filter Mode" switches:

"Off": Defeats

the

filter completely, allowing

the

full range

of

frequencies present at

the

inputs

to feed

the

amplifier. This

is

useful for systems

utilizing outboard active crossovers or requiring

full-range reproduction from one or more

of

the

XD800/8v2's channel pairs.

"LP" (Low-Pass): Configures the filter to

attenuate frequencies above the selected filter

frequency at a rate

of

12

dB

per

octave. This is

useful for connection

of

subwoofer(s) to one

or more

of

the XD800/8v2's channel pairs in a

hi-amplified system.

"HP" (High-Pass): Configures the filter to

attenuate frequencies below the selected filter

frequency at a rate

of

12

dB

per

octave. This

is

useful for connection

of

component speakers to

one

or

more

of

the XD800/8v2's channel pairs

in

a hi-amplified system.

2) "Filter Freq. (Hz)" The filter frequency

markings

surrounding

this rotary control

are for reference purposes

and

are generally

accurate to within

1/3

octave or better.

If

you

would like to select the filter cutofffrequency

with a higher level

of

precision, consult the

chart

in Appendix B (page

15).

Tuning

Hint:

If

you are using the XD800/8v2

to drive a subwoofer system

("LP"

mode), a

component satellite speaker system ("HP"

mode)

or both, 80

Hz

is

a good baseline "Filter Freq.

(Hz)" setting. After properly adjusting

the

"Input

Sens.", as outlined in Appendix A (page

14),

you

can

fine

tune

the

"Filter Freq. (Hz)" control to

achieve the desired system frequency response.

The HD-RLC connects to

the

jacklabeled

"Remote Level Control"

on

the

Connection Panel

of

the

amplifier using a

standard

telephone cable

(supplied with

the

HD-

single HD-RLC controller using a simple,

non-duplex phone line "splitter"

and

multiple

clockwise rotation, the audio will mute

completely. At full clockwise rotation

the

SPEAKER OUTPUTS

The XD800/8v2's speaker outputs are designed

to accept

16

AWG - 8 AWG wire.

To

connect the

speaker wires to the amplifier, first back out the

set screws on the top

of

the terminal block, using

the supplied 2.5

mm

hex wrench. Strip 1/2 inch

(12

mm)

of

insulation from the end

of

each wire

and

insert the bare wire into the terminal block,

seating it firmly so that no bare wire

is

exposed.

While holding the wire in place, tighten the set

screw firmly, taking care not to strip the head

of

the screw.

Each pairofthe XD800/8v2's channels are

designed to deliver power into speaker loads equal

to orgreater than 2 ohms when using a "stereo"

configuration and speaker loads equal to orgreater

than 4 ohms when using a "bridged" configuration.

OIMPORTANTI

Speaker

loads below 2

ohms

nominal

per

channel

(or 4

ohms

bridged)

are

not

recommended

and

may

cause

the

amplifier

to

initiate

a

protection

mode

which reduces power

output.

BRIDGING CONSIDERATIONS

Bridging is the practice

of

combining the

output

of

two amplifier channels to drive a single

load.

When

bridged, each channel produces

signals

of

equal magnitude, but opposite polarity.

The combined output

of

the two channels

provides twice the output voltage available from a

single channel. The XD800/8v2 has been designed

for bridging

of

its channel pairs without the need

for input inversion adaptors.

To

bridge a pair

of

channels, use the "Left +"

and

"Right

-"

speaker connectors only. The

"Left

-"

and

"Right

+" remain unused.

When

bridged, each channel

pair

will deliver

optimum

power into a single 4

ohm

load.

10

I

JL

Audio-

OIMPORTANTI

When

a

pair

of

channels

are

bridged,

they

will deliver

200W

x 1

into

a 4

ohm

load

or

150W x 1

into

an

8

ohm

load.

Operating

a

pair

of

bridged

channels

into

a

load

lower

than

4

ohms

is

not

recommended.

Because a

bridged

pair

of

channels

requires

that

both

channels receive

input,

you

need

to

connect

both

left

and

right

inputs

to

the

source

unit.

Connection

of

only

one

input

will result

in

reduced power

output,

increased

distortion

and

can

cause

the

amplifier

to

overheat.

Do

not

do

this!

When

a pair

of

the XD800/8v2's channels are

operating in bridged mode, the output will be in

mono (only one channel). This mono channel

can contain right channel only information,

left channel only information

or

the

sum

of

the information from

both

the right

and

left

channels.

In

order to achieve one

of

these options,

configure the inputs to that pair

of

channels

in

one

of

these two ways:

1)

Left

Channel

Only

or

Right

Channel

Only

Information:

If

you wish to send a left-only or

right-only signal to a pair

of

the XD800/8v2's

channels, use a "Y-Adaptor" to split the single

channel signal into

both

left

and

right RCA

inputs. This option

is

useful when using a

pair

of

the XD800/8v2's channels to drive left

channel speakers only

and

another pair

of

the

XD800/8v2's channels to drive right channel

speakers only.

2)

Left +

Right

Channel

Information:

When

bridged and fed by a stereo input, a pair

of

the XD800/8v2's channels will automatically

combine the left

and

right channels into a

summed

mono (left + right) channel. This

option

is

useful when using a pair

of

the

XD800/8v2's channels to drive a subwoofer

system or a

summed

mono center channel.

APPENDIX

A:

Input

Sensitivity Level Setting

Following the directions below will allow the

installer to adjust the input sensitivity

of

each

amplifier channel pair simply

and

easily in just a

few

minutes using equipment which

is

commonly

available in installation bays.

Necessary Equipment

• Digital

AC

Voltmeter

• CD with a sine-wave test tone recorded at

0 dB reference level in the frequency range

to be amplified for

that

set

of

channels

(50

Hz

for subwoofer channels, 1

kHz

for a

midrange application). Do not use attenuated

test tones

(-10

dB, -20 dB, etc.).

The Nine-Step Procedure

I) Disconnect the speaker(s) from the

amplifier's speaker output connectors.

2)

Turn offall processing (bass/treble, loudness,

EQ, etc.) on the source unit, processors (if

used)

and

amplifier. Set fader control to center

position

and

subwoofer level control to 3/4

of

maximum

(ifused to feed the XD800/8v2).

3)

Turn

all

of

the

amplifiers'

"Input

Sens."

controls all

the

way down.

4)

Set

the

source

unit

volume to 3/4

of

full

volume. This will allow for reasonable gain

overlap with moderate clipping at full volume.

5)

Using the chart on this page, determine the target

voltage for input sensitivity adjustment according

to the nominal impedance ofthe speaker system

connected to the amplifier outputs.

6) Verify

that

you have disconnected the speakers

before proceeding. Play a trackwith

an

appropriate sine wave (within the frequency

range to be amplified by the XD800/8v2) at 3/4

source

unit

volume.

7) Connectthe

AC

voltmeter to the speaker output

connectors

of

the amplifier.

If

the channel

pair

is

operating in stereo, it

is

only necessary

to measure one channel.

If

bridged, make sure

you test the voltage at the correct connectors

(L+

and

R-).

8)

Increase the

"Input

Sens." control until

the

target voltage

is

observed with the voltmeter.

9) Once you have adjusted

the

XD800/8v2 to

its

maximum

low-distortion

output

level,

reconnect the speaker(s). The

"Input

Sens."

controls

can

now be adjusted

downward

if

the

amplifier requires attenuation to achieve the

desired system balance.

APPENDIX D: TROUBLESHOOTING

11

How

do

I properly set

the

input

sensitivity on

my

amplifier?"

11

My

amplifier

doesn't turn on."

Please refer to Appendix A (page 14) to set

the

input sensitivity for

maximum,

low-distortion output.

Check

the

fuse,

not

just visually,

but

with

a

continuity

meter. It

is

possible for a fuse to have

poor

internal connections

that

cannot

be found byvisual inspection. It

is

best to take the

fuse

out

of

the holder for testing.

If

no

problem

is

found

with

the fuse, inspect the fuse-holder.

Check

the

integrity

of

the

connections

made

to each

of

the

"+12VDC", "Ground",

and

"Remote" terminals. Ensure

that

no

wire insulation

is

pinched by

the

terminal

set screw

and

that

each connection

is

tight.

Checkto make sure there

is

+

12V

at the "Remote" connection

of

the

amplifier.

In

some cases, the

turn-on

lead from the source unit

is

insufficient to

turn

on

multiple devices

and

the use

of

a relay

is

required.

To

test for this problem,

jump

the

"+

12VDC" wire

to the "Remote" terminal to see

if

the amplifier

turns

on.

''I hear a repetitive ticking or popping sound coming

out

of

the

speaker(s)."

Check

the

speaker wires for a possible short, either between

the

positive

and

negative leads

or

between either speaker lead

and

the

vehicle's chassis ground.

If

a

short

is

present, you will

experience distorted

and/or

attenuated output. The "Status

LED"

will

turn

Amber

(yellow)

in

this situation. It

may

be

helpful to disconnect

the

speaker wires from

the

amplifier

and

use a different set

of

wires

connected

to a test speaker.

Check

the

nominal

load impedance to verify

that

each channel

of

the

amplifier

is

driving a load equal to

or

greater

than

2

ohms

in

stereo

mode

(4

ohms

bridged).

11

My

amplifier's

output

fluctuates

when

I

tap

on it or

hit

a bump."

16

I

JL

Audio-

XD800/8v2 Owner's Manual

Check

the

connections to the amplifier. Make sure

that

the

insulation for all wires has been stripped back far enough to

allow a good contact area inside

the

terminal

block.

Check

the

input

connectors to ensure

that

they

all are

making

good

contact

with

the

input

jacks

on

the

amplifier.

11

My

amplifier shuts

off

once in a while, usually

at

highervolumes."

Check

your voltage source

and

grounding point.

The

power supply

of

the XD800/8v2 will operate with charging system voltages

down to

10V.

Shutdown problems at higher volume levels

can occur when the charging system voltage (or remote

turn-

on

voltage) momentarily drops below

10V.

These dips can

be

of

very short duration making

them

extremely difficult

to detect with a

common

DC voltmeter.

To

ensure proper

voltage, inspect all wiring

and

termination points.

It

may

also be necessary to upgrade the

ground

wire connecting the

batteryto the vehicle's chassis

and

the power wire connecting

the alternator to the battery. Manyvehicles employ small

(10

AWG- 6

AWG)

wire to ground the battery to the vehicle's

chassis and to connect the alternator to the battery.

To

prevent

voltage drops, these wires should be upgraded to 4 AWG

when installing amplifier systems with main fuse ratings

above 60A. Grounding problems are

the

leading cause

of

misdiagnosed amplifier "failures."

11

My

amplifierturns on,

but

there

is

no output."

Check

the input signal using

an

AC

voltmeter to measure the

voltage from the source

unit

while

an

appropriate test tone

is

played

through

the source

unit

(disconnect the input cables

from the amplifier prior to this test). The frequency used

should be

in

the range that

is

to be amplified by the amplifier

(example:

50

Hz

for a sub bass application

or

1kHz

for a full

range I high-pass application). A steady, sufficient voltage

(between

0.1

and

8.0-volts) should be present at the output

of

the signal cables.

Check

the

output

of

the amplifier. Using the procedure explained

in

the previous check item (after plugging the input cables back

into the amplifier) test for output at the speaker outputs

of

the amplifier. Remove the speaker wires from the amplifier

while doing this to prevent unpleasant noise

and

possible

speaker damage. Turn the volume up approximately

half

way.

SV

AC

or

more should be measured at the speaker

outputs. This output level can vary greatly between

amplifiers

but

it should not be

in

the millivolt range with

the

source

unit

at

half

volume.

If

you are reading sufficient

voltage, checkyour speaker connections as explained below.

Check

to ensure

that

the speaker wires are

making

a good

connection with the metal inside the terminal block. The

speaker wire connectors are designed to accept up to 8 AWG

wire. Make sure to strip the wire to allow for a sufficient

connection with

the

metal inside the terminal block.
