PRECAUTIONS
I
English I English
Before installing
the
components, please carefully read all
of
the instructions contained in
this
manual.
It
is advisable
to
carefully
follow
the highlighted instructions. Failure
to
respect these instructions
may
cause unintentional harm
or
damage
to
the
components.
SAFETY
CONSIDERATIONS
1. Make sure
your
car has 12
VDC
voltage negative ground electric system.
2.
Check
your
alternator and
battery
condition
to
ensure
they
ca
n handle
the
increased cons
um
ption.
3.
Do
not
carry
out
any installation inside
the
engine
compartment
or
exposed
to
water, excessive humidity,
dust
or
dirt
.
4. Never run cables outside
the
vehicle or install
the
amplifier
next
to
electronic gearcases.
s.
Install
the
amplifier in
the
vehicle parts where temperature is be
tw
een
O"C
(32"
F)
and
55"(
(131
"F). Let
the
amplifier outer profile be
at
least 5
em
(2
")
far
from
possible walls. There
must
be
good air circulation where the amplifier is installed. If you cover
the
heat sink. t
he
amplifier goes in protection.
6. The
amplifier
can reach
tempera
tures of around
80"(
I176.
F).
Make sure
it
is
not
dangerously
hot
before touching it.
7. Periodically clean
the
amplifier
without
using aggressive solvents
that
might
damage
it.
Do
n
't
use compressed air, since
it
would push solid parts
in
the
amplifiers. Dampen a piece
of
cloth
with
wat
er and soap, wring
it
and clean
the
amplifier. Then use a piece
of
cloth dampened
with
water
only; eventually clean
the
amplifier
with a
dry
piece
of
cloth.
8.
Make
sure
the
location you chose
for
the
components does n
ot
affect
the
correct functioning
of
the
vehicle mechanical and electrical devices.
9. Make sure power cable is
not
short
circuited during installation and connection
with
the
battery.
10. Use extreme caution
when
cutting
or
drilling
the
car plate, checking there are no electrical
wiring
or
structural element underneath.
11. When positioning
the
power
supp
ly
ca
ble, avoid
to
run
the
wire over or through sharp edges
or
close
to
moving mechanical devices. Use rubber
grommets
to
protect
the
wire
if
it
runs in a hole
of
the
plate or proper materials
if
it
is
close
to
heat-generating parts.
12. Make sure all
the
cables are proper
ly
secured all along
their
length. Also, make sure
their
outer protective jacket is flame r
esistant
and self
extinguishing. Use a clamping screw to secure positive and negative cables
just
close
to
t
he
amplifier respective power supply terminal blocks.
13. Choose
the
cable gauge according
to
the
amplifier power and
to
the suggestions you can find here. Use high quality cabl
es,
connectors and
accessories,
as
you can
find
in
the
Connection catalogue.
14. Pre-plan
the
configuration
of
your new amplifier and
the
best wiring routes
to
ease installation.
15.1n order
to
avoid incidental damag
e,
keep
the
product
in
the
or
iginal packaging
until
you are ready
for
the
final install
at
ion.
16
. Always wear protective eyewear when using tools, as
splints
or product residue
may
become airborne.
TYPICAL
INSTALLATION
SEQUENCE
If
you have any questions please refer
to
the
Advanced Manual you can
find
available on www.hertzaudiovideo.com or contact your Hertz dealer
or
Hertz authorized service
for
assistance.
1. Before installing
the
amplifier
turn
off
the
source and all other ele
ct
ronic devices in
the
audio sy
stem
to
prevent any damages.
2. Using a
ca
ble
with
adeq
uat
e
AWG
(see chart: Power Supply
Ca
ble), run the power
wire
from
the battery location
to
the
amplifier
mounting
location.
3. Connect
the
power supply
with
the
correct polarity. connect
I+)
term
inal
to
the
cable coming
from
the
battery
and
1-)
terminal
to
the
car chassis.
4.
Put
an insulated
fuse
holder
40
em max
far
from
the
battery positive terminal; connect one end
of
the
power cable to
it
after
connecting
the
ot
her
end
to
the
amplifier. Do
not
mount
the
fuse.
5.
To
ground the device 1-)
in
the
right
way, use a screw
in
the
vehi
cle
chassis; scrape all paint or grease
from
the
metal
if
necessary, checking wi
th
a
tester
that
there is
continuity
between
the
battery negative
terminal(-)
and
the
fixing po
in
t .
If
possible, connect all components
to
the
same
ground point;
this
solution rejects
most
noise which can be generated during
the
audio reproduction.
6. Route all signal cables close
together
and away
from
power cables.
7. Connect
the
RCA
input
cables,
the
applied signal
must
be between 0.2 VRMS and 5 VRMS.
8. Connect
the
hi
gh level
inputs
using
the
proper plug. Applied signal
must
be between 0.8
VRMS
and
20
VRMS.
Don't use
it
if you are
already using Pre In preamplified connection.
9. Connect
the
speaker
output
using 10
AWG
max speaker cable.
10. Don't connect(-)
Land
1-) R
sp
eaker
outputs
to
ge
ther
.
If
you use an external stereo crossover, make s
ur
e
that
its
negative poles are
not
connected
together.
11. The amplifier
turns
on by connecting
the
remote
turn
on terminaiiREMOTE
IN)
to
the
source specific output. The amplifier
turns
on automatically,
without
remote signal, also
if
using high. level
inputs
(Speaker I
N)
by setting
the
"AUTO
TURN
ON"
switch
to
position
ON.
12. The
LED
on
the
front
panel
lights
up
green indicating
that
the
product is on. The
LED
lights up red
if
the
outputs
go on overload,
if
the
thermal
protection is triggered,
if
the
speaker cables
short
circuit
with
the
vehicle chassis and
if
the amplifier is malfunctioning.
13
.
Th
e
fu
se/s
is/
are located near
the
power supply and speaker t erminals. To replace, remove the
fuse/s
from
the
housing. Always replace
the
fuse
of
the
same rating.
14. Secure all auxili
ar
y devices you
built
to
in
sta
ll
the
co
mpone
nt
s to
the
vehicle structure; this insures stabi
lity
and safety
wh
i
le
driving. The amplifier
detachment
while driving can seriously damage
the
people
in
t
he
vehicle and
other
cars.
15. When installation is over, check
the
system's wiring and make sure all connections were done in
the
right
way.
16.
Put
the
fuse into
the
fuse holder. The fuse value
will
ha
ve
to
be
30%
higher
th
an
the
amplifier
built-in
one. In case
the
cable supplies several
amplifiers,
the
fuse value
will
ha
ve
to
be
30%
hi
g
her
than
the
sum
of
the
values
of
all
othe
r fuses in
the
amplifiers.
17.
Li
