DS18 H-KO AMPS
INTRODUCTION
INSTALLATION
Fully variable crossovers promote installation
ease and save the cost of outboard crossovers.
Additionally, they may be used in conjunction
with outboard passive or active crossovers,
depending on the complexity required by the
system. The 12 dB per octave slope offers steep
roll-off above or below the selected frequency.
Against Overload, Short Circuit, Thermal, and
Reverse Polarity. These protection features are
designed to protect the amplifier from misuse,
as well as from common causes of amplifier
failure.
The DS18 HOOLIGAN KO Car amplifiers offer high quality audio reproduction for
the audiophile and the everyday listener alike. All models feature fully variable
crossovers with 12dB per octave slopes, allowing you the ability to tailor the
sound to best fit the speakers and your listening preferences.
Ensures solid electrical connections that resist
corrosion.

Protection Circuitry
Professional installation by an authorized DS18 H-KO amps dealer is highly
recommended! Otherwise, the performance of your new gear may not be
satisfactory. In the event that you decide to do your own installation, please read
and follow this manual very carefully. Failure to do so may compromise the
integrity of this product, your automobile, and possibly void the product warranty.
Amplifiers are generally mounted in the hatch/ trunk area of a car or SUV, and
under or behind the seat of most pick-up trucks. Select a location that will provide
adequate ventilation for the amplifier. Avoid mounting the amplifier with the fins
down. The fins should be facing up either vertically or horizontally. Secure the
amplifier with the screws provided.
Thank you for choosing DS18 HOOLIGAN KO amps!
To Take full advantage of the DS18 HOOLIGAN KO amps you have just purchased,
please read and follow the instructions in this manual. As with all of our products,
professional installation by an authorized DS18 dealer is highly recommended!

CROSSOVER CONTROLS
INPUT SECTION
Before securing the amplifier, inspect the mounting location carefully to ensure
that you do not drill into or damage any electrical, hydraulic, fluid or fuel lines.
Because of the wide range of head unit output configurations all DS18 H-KO amps
have an adjustable input sensitivity of “Gain”. The gain is not a volume or a power
limiting control like a throttle. It makes the amp more sensitive to input from the
stereo; with the gain up, the amp will reach full output at a lower volume setting
on the deck. At higher gain settings the amp also becomes more and more
sensitive to noise from the car’s electrical system. Try to run the gain at the lowest
setting possible for your system.
There is no correct gain
setting, because
speakers require
different power
demands to reach the
same output, the gains
most often need to be
used to compensate for
these differences. If you
tried to set all the gains
at half way you would probably find the system didn’t sound very good. Using
good judgment and listening carefully to each speaker is still the best way to tune
a system.
A crossover is a device
that removes unwanted
frequencies from a
speaker or amplifier. A
tweeter can easily be
destroyed by bass notes
if they are not filtered
out. Likewise a
subwoofer will not
sound natural if it is
playing midrange
notes. A crossover
removes these sounds from the speaker. As you might guess, careful adjustment
in need to ensure that all the speakers are playing the right sounds and that you
are left with no “holes” or low spots in the frequency response.

BASS BOOST
SPEAKER OUTPUTS
INSTALLATION INSTRUCTIONS
DS18 H-KO amplifiers have
an adjustable bass boost.
Begin your adjustments at
low volume. If you do not
hear any improvement
then woofer does not
need any bass boost.
Use Bass Boost carefully.
The demands on power
output are tremendous.
Try to minimize the use by changing woofer position or the enclosure size.
This amplifier is equipped
with a large block style
terminal for speaker
connection. Make this
connection carefully and
neatly. Strip your wire
back and twist the
exposed leads and insert
them into the block
terminal while being
careful that there is no
loose or frayed strands of
wire and tighten the Allen head screw down on the terminal till the wire is tightly
secured in place. If the wires ever come in contact with each other the amplifier
will go into protection.
1. Before you start, disconnect the negative cable from the car battery.
Tape up the end so it is isolated from the battery.
2. Run an appropriate gauge wire from the battery to the amplifier. Plan this part
of the installation carefully. This cable will carry very high current, if it should
short to the body and it is not properly fused it could catch fire.
3. Connect the power wire to the battery using a fuse capable of the total current
load of all amplifiers connected. Don’t install the fuse yet. Wait until the end.
Locate the fuse as close as possible to the battery. If the fuse is further than 18
inches (wire length) from the battery you should reevaluate the wire and fuse
placement.
4. Find the closest clear metal area to the amp for a ground. Sand, grind or
scrape all paint and undercoating from the body and screw the ground
securely in place. 4

It is advisable to test the ground with an ohmmeter between the ground cable and
the negative battery cable to ensure a good low resistance connection. Some
allows used in modern cars do not offer the best ground. If you believe this is the
case - first consult with the vehicle manufacturer.
5. Run the speaker wire to the speakers. It is advised that you leave some
extra wire at this point. You can fix it later.
6. If you haven’t done so already, mount the amp now.
7. Connect the power and ground to the amplifier.
ONLY AFTER THIS STEP - SHOULD YOU INSTALL THE FUSE AT THE BATTERY.
8. Connect the remote wire from the head unit to the amplifier.
Now is a good time to turn on the amp for the first time. Make sure it turns
on properly and does not go into protection mode.
9. Connect the speaker wires to the amp and speakers (make sure the amp
is off first). Make sure the polarity (+) and (-) is correct.
10. Connect the RCA’s to the amp.
11. Double check the amplifier controls at this time. Make sure everything is
set correctly for your system.
12. Now you’re ready to play it for the first time. It is best to leave the gain all
the way down at first. Start with the head unit volume low and work your
way up.
13. Now you can tune the amp. Take your time and make only one
adjustment at a time. It may take some time to get the system fully
adjusted. During this time the amp is drawing current from the battery. You
should check the battery voltage from time to time and recharge it, if it
gets low. That’s it. You’re done.
Now have fun.
