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.
