INSTALLATION

»

PRE

-

1. Find a suitable location in the vehicle to mount the amplifier.

2.

Make sure there is sufficient air

flow

around the intended mounting location.

3.

Bolt the amplifier to the mounting surface.

4.

Counect the power ground terminal to the nearest point on the

cl1assis

of the car.

Keep

this ground wire less than one meter (39") in length. Use 8 gauge wire.

5.

Counect the remote terminal to the remote output

of

the head unit using

14

gauge wire.

6. Counect

an

empty fuse holder within

300

mm

(12")

of

the battery and run 8 gauge

or

larger high quality cable from this fuse to the amplifier location.

7.

Make sure there is no fuse in this fuse holder. Then make the connection to the

"BATf"

connection on the amplifier.

8.

If

multiple amplifiers are being used, use cables (eacll with its own fuse at the battery)

or a

#0

or

#2

cable from the fuse holder at the battery to a distribution block at or near

the amplifier's location.

9. Connect all line inputs and outputs using high-quality

RCA-RCA

cables.

10.

Iusert fuse(s) at the batteryfuseholder(s).

11. Recheck all connectious before powering up.

12.

Set all level controls to their least sensitive positions and set all crossover controls,

switcl1es,

etc. to the desired frequency or position.

13.

Once the system is powered up, set the volume control on the head unit to about the

2 o'clock position, and then set all the amplifiers'level controls for maximum output

level.

14.

Further fine tuning of the various controls may

be

necessary to obtain the desired results.

•

Before

you

drill or

cut

any

holes,

investigate

your

car's

layout

veIY

carefully.

Take

care

when

you

work

near the

gas

tank,

fuel

lines,

hydraulic lines and

electrical

wiring.

• Do

not

operate

the

amplifier

when

it

is

unmounted.

Attach all

audio

system

components

securelywithin

the

automobile

to

prevent

damage,

especially

in

an

accident.

•

Do

not mount this amplifier

so

that the

wire

connections are unprotected or in a pinched

condition,

or likely

to

be

damaged

by

nearby

objects.

Be

sure

to

select

a

location

inside

your

vehicle

which

has adequate

ventilation.

•

Before

making or

breaking

power

connections

in

your

system,

disconnect

the

vehicle

battery.

Confirm

that

your

head unit or other equipment

is

turned

off

wbile

connecting the input jacks and speaker

terminals.

•

If

you

need

to

replace

the

power

fuse,

only

replace

it with a

fuse

identical

to

that supplied

with

the

system.

Using

a

fuse

of a different

type

or rating

may

resnlt

in

damage

to

your

system

which

isn't

covered by the manufacturer's warranty.

is obtainable

this way.
