OWNER’S MANUAL
CONGRATULATIONS!
Thank you for purchasing the Wet Sounds Hydro-TechTM X (HTX) series amplifier.
Wet Sounds represents the ultimate in High-Performance Marine Audio. Wet
Sounds HTX Series Marine Amplifiers are designed to be a complete solution for
every type of extreme marine application. HTX 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, and extended inputs. HTX amplifiers are a
well-balanced match for all of the Wet Sounds TM 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 structures of the boat. 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
Your amplifier does NOT make power; it converts power, or current, from your
boat’s 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
amplifiers on the market today. Should your voltage or current drop too low
the amplifier will drop below the rated output. Make sure your boat’s charging
system is in good working order. Any high-performance audio amplifier will
increase the demand for your alternator and battery. If you are unsure have
your charging system checked system testing by a professional technician.
RUNNING THE WIRING CABLES
Always keep the signal cable and the power cables separated to prevent the
possibility of inducing noise into the system
Carefully run the power and the signal cables through the boat. Always keep
all the wires tight and tied down to prevent the power wire from shorting and
reduce the risk of fire. A 4 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.
AMPLIFIER CONNECTIONS
Make sure that the +12 volt cable is NOT connected to the battery while
making any of the connections until all the connections and the fuse are
installed Power Connections
The HTX Series is designed for 4 AWG Power wire (+12 V) and
Ground wire (GND). You will need to prepare the wire by removing 5/8″ on the
protective shielding on the power and ground wire. Then take a Phillips 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 tighten the screw back
into the terminal block. You will do the same for the Ground wire. See below
REMOTE CONNECTION
This amplifier is designed to accept a 12 AWG — 16 AWG wire input on the
terminal block for speaker outputs 1 and 2. (Diagram A). The Remote Turn-on is
how the amplifier knows when to turn on and off. This is typically connected
to the remote output wire on an aftermarket radio. When connecting this
amplifier to a factory radio, you will need to find a +12 volt accessory wire
that switches on and off with the key.
AMPLIFIER SIGNAL INPUTS
Connect the RCA outputs from the source unit into the inputs of the amplifier.
The HTX Series has 1 pair of inputs for each pair of channels (6 channels are
shown below, other models will vary).
There are 2 different input selection switches.
The first is to designate 2 or 4-channel input. You can select 2 channel
inputs when only using 1 set of RCA inputs to allow all 4 channels to have
output (CH 1,2,3, & 4). The next is to turn on or off the inputs for channels
5 & 6.(See below) Ch 5 & 6 can be carried over from inputs 1 & 2 when in 2CH
mode, or a separate set of RCA cables can be used in 6CH mode. note if you
only use the amplifier in 2 channel input mode you will not have fading
capabilities between the front and rear outputs.
SPEAKER TERMINAL INPUTS The HTX
The Series utilizes removable speaker terminal blocks for easier
installations and stronger power connections. The terminal blocks are designed
to accept 12 AWG- 16 AWG speaker wire. When preparing the wire you will need
to strip 5/8″ of the cable’s protective shielding. Then take a small Phillips
or flat head screwdriver and back out the screw on the terminal block. Insert
the speaker wire into the terminal block and then tighten the screw back into
the terminal block. (DO NOT OVERTIGHTEN) (See below)
POWER INDICATOR
The amplifier is equipped with a dual illumination LED on the top of the
amplifier that the Wet Sounds logo badge is mounted on. This amplifier is
equipped with an advanced diagnostic system controlled by a microprocessor. In
the event that the unit goes into protection for any reason, it will flash a
diagnostic code. The different sequences indicate the “Code” for faster
troubleshooting. When the amplifier first turns on the LED will flash blue.
Once the amplifier is ready for use the LED light will change to solid blue.
If the amplifier is in protection mode (over-voltage, under-voltage, DC
offset, thermal heating or speaker short) the LED light will flash a red
diagnostic sequence.
See the troubleshooting section for further detail.

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 a throttle. 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.
- Tum the gain all the way counterclockwise to the “min” point on the amp.
- Increase the head unit/radio volume to % of the maximum volume output while paying your favorite style/genre of music.
- Gently turn the gain clockwise to increase the output of the amplifier 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 the distortion is no longer present.
If you need further assistance please contact Wet Sounds Technical Services
Department.
Crossover Controls
This amplifier is designed to play frequencies between 50 Hz and 250 Hz. The
amplifier is equipped 2 different optional settings. High-Pass (HI) or Low-
Pass (LO) (See below)
** “High-Pass”
designed to play only the frequencies above where the crossover is set at.
“Low Pass”**
designed to play only the frequencies below where the crossover is set at.
TROUBLESHOOTING
If you are experiencing problems with your amplifier after Ada installation follow these procedures to try and remedy the problem.
- Check your fuse and replace if necessary.
- Confirm your Ground wire has a good connection.
- Make sure your remote wire and power wire has +12 Volts.
- Make sure your battery has 12 volts.
- Confirm that the amplifier LED color is blue. If the light flashing is red than the amplifier is in protection mode. if the light is red check the following items below:
A. See what sequence is flashing by referencing the chart below
B. Confirm that the speaker is not blown.
C. Confirm that there are no loose wires that could be grounding out the amplifier.
D. 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.

will contiunue to play. After a fault connection is cleared, the error code
will continue to flash, while the logo is still illuminated blue. Please
contact Tech Support for additional assistance, questions, etc.
BRIDGED AUDIO RCA CONFIGURATION
When connecting two speakers in bridged mode on channels 1-4 on the HTX-4 or
HTX-6. the left and right RCA’s must be split to retain stereo separation.
This means you will have left audio out of the left speaker and right audio
out of the right speaker. You must also switch to 4CH on the input mode
section of the control panel on top of the amplifier (See the switch image
below for an example). If you choose not to configure using this method and
just use 2CH mode, then both speakers will play in mono and not stereo.
Two dual male RCA Y-Splitters are required for this configuration.
Please contact Wet Sounds Technical Support at a77.938.7757 if you need any
assistance or how to bridge your HTX Series Amplifier.
