Congratulations!
Thank
you
for
purchasing
the
Wet
Sounds
Hydro-
Tech™
series
amplifier.
Wet
Sounds
represents
the
ultimate
in
high
performance
Marine
Audio.
Wet
Sounds™
Hydro-Tech™
Series
Marine
Amplifiers
are
designed
to
be
a
complete
solution
for
every
type
of
extreme
marine
application.
The
Hydro-
Tech™
amplifiers
use
superior
performance
circuitry
by
utilizing
Class
D
Power
Supplies.
These
amplifiers
have
extreme
power
output
packed
inside
a
small
chassis,
thermal
overload
protection,
flexible
crossovers,
optional
elevated
feet,
extended
inputs.
Hydro-
Tech™
amplifiers
are
a
well
balanced
match
for
all
of
the
Wet
Sounds™
products.
Warning
We
build
all
Wet
Sounds™
products
to
play
at
high
volumes
for
extended
periods
of
time.
Your
ears
however
are
not
designed
for
high
volume
listening.
This
product
can
easily
generate
high
volumes
that
can
permanently
damage
your
hearing.
We
urge
you
to
limit
your
exposure
to
very
high
volume
sound.
You
may
also
find
your
state
has
laws
governing
the
volume
of
an
audio
system.
Please
be
aware
of
all
local
and
state
laws
in
your
area.
A
Properly
tuned
and
operated
audio
system
will
deliver
years
of
enjoyment
when
used
properly.
Warning
Please
check
the
installation
location
before
you
begin.
Do
not
cut
any
of
the
boats
structure.
Pay
close
attention
to
what
items
are
behind
the
panels
and
carpet.
Often
the
manufacturer
will
hide
wires,
mechanical
or
other
electronic
devices
in
the
exact
locations
you
wish
to
install
in.
Installation Instructions
Wet
Sounds™
Marine
Amplifiers
are
designed
for
easy
installation
in
your
boat.
To
ensure
proper
installation
of
your
new
purchase
please
follow
all
the
suggestions
listed
below.
If
you
do
not
have
experience
with
marine
electrical
and
mechanical
systems
contact
a
professional
installer.
Paying
a
qualified
installer
is
almost
always
cheaper
than
paying
a
dealership
to
repair
your
boat.
Locating
the
Amplifier
The
amplifier
must
be
securely
mounted
to
a
solid
surface.
Please
select
a
dry
location
to
mount
your
amplifier.
All
Wet
Sounds™
products
are
designed
to
operate
in
humid
environments
however
direct
contact
with
water
can
damage
the
electronics.
Do
not
mount
the
amplifier
to
any
area
that
may
have
excessive
vibration
(like
a
subwoofer
enclosure).
Position
the
amplifier
in
an
area
that
receives
sufficient
airflow
for
proper
heat
dissipation.
Supplying
Enough
Power
The
Laws
of
Nature
Your
amplifier
does
NOT
make
power;
it
converts
power,
or
current,
from
your
boats
electrical
system
and
converts
it
into
high
power
musical
energy.
If
the
amp
can't
get
all
the
power
it
needs
it
will
not
produce
its
full
output.
Your
Wet
Sounds™
amplifier
will
produce
full
output
longer
than
other
amplifies
on
the
market
today.
Should
your
voltage
or
current
drop
too
low
the
amplifier
will
drop
below
the
rated
output.
Make
sure
your
boats
charging
system
is
in
good
working
order.
Any
high
performance
audio
amplifier
will
increase
the
demand
on
your
alternator
and
battery.
If
you
are
unsure
have
you
charging
system
checked
system
testing
by
a
professional
technician.

Running the
Wiring
Cables
**Always
keep
the
signal
cable
and
the
power
cables
separated
to
preventthe possibility of
inducing
noise
into the
system**
Carefully
run
the
power
and
the
signal
cables
through
the
boat.
Always
keep
all
the
wire
tight
and
tied
down
to
prevent
the
power
wire
from
shorting
and
reduce
the
risk
of
fire.
A4
AWG
or
larger
wire
should
be
used
for
power
and
ground
connections.
We
recommend
a
fuse
to
be
installed
on
the
power
wire
within
18
inches
of
the
battery
for
safety.
We
recommend
a
50
amp
fuse.
Amplifier
Connections
**
Make
sure
that
the
+12 voltcable is
NOT
connected to
the
battery
while making any
of
the
connections until all
the
connections
and
the fuse
are
installed
**
Power Connections
The
HT-4
is
designed
for
4
AWG
Power
wire
(
+12
V)
and
Ground
wire
(GND).
You
will
need
to
prepare
the
wire
by
remove
5/8"
on
the
protective
shielding
on
the
power
and
ground
wire.
Then
take
a
flat
head
screwdriver
and
back
out
the
screws
on
the
terminal
block.
Insert
the
+
12
volt
wire
into
the+
12V
side
of
the
terminal
block
and
then
ti
hten
the
screw
back
into
the
terminal
block.
You
will
do
the
same
for
the
Ground
wire.
See

Setting
up
the
Amplifier
Input
Selection
Because
of
the
wide
range
of
head
unit/radio
output
configurations
all
Wet
Sounds™
amplifiers
have
an
adjustable
input
sensitivity
or
''GAIN".
The
gain
is
NOT
a
volume
or
a
power
limiting
control
similar
to
athrottle.
It
makes
the
amplifier
more
sensitive
to
input
from
the
stereo.
When
the
gain
is
turned
up
the
amplifier
will
reach
full
output
at
lower
volume
levels
on
the
head
unit/radio.
Also
when
the
gain
is
set
too
high
the
amplifier
becomes
much
more
sensitive
to
noise
from
your
boats
electrical
system.
Adjusting
the
Gain
You
will
need
a
small
flat
head
screwdriver
and
select
the
style/genre
of
music
you
primarily
enjoy
listening
to.
Here
are
3
easy
steps
to
follow.
1.
Turn
the
gain
all
the
way
counter
clockwise
to
the
"min"
point
on
the
amp.
2.
Increase
the
head
unit/radio
volume
to
3
A
of
the
maximum
volume
output
while
playing
your
favorite
style/genre
of
music.
3.
Gently
turn
the
gain
clockwise
to
increase
the
amplifiers
output
until
the
desired
level
of
output
is
achieved.
**You
will
repeat
these
steps
for
both
the
front
and
rear
channels
independently**
You
should
not
hear
any
distortion
in
your
speakers
at
this
level,
if
you
do,
slowly
turn
down
the
gain
until
distortion
is
no
longer
present.

Bass Boost
This amplifier is equipped with a variable bass boost for Odb to 18db of signal boost which will
increase the signal output @ 45 Hz .. (See below)
Troubleshooting
If you are experiencing problems with your amplifier after installation follow these
procedures to try and remedy the problem.
1. Check your fuse and replace if necessary.
2. Confirm your Ground wire has a good connection.
3. Make sure your remote wire and power wire has+ 12 Volts.
4. Make sure your battery has 12 volts.
5. Confirm that the amplifier l.e.d. color is blue. If the light is red than the amplifier is in protection
mode. If the light is red check the following items below:
A. Confirm that a speaker is not blown.
B. Confirm that there are no loose wires that could be grounding out the amplifier.
C. Check that the amplifier has sufficient air circulation where it is located. Insufficient air flow
and overdriving the audio system could result in the amplifier going into protection to
preserve the amplifier.
