Thank you for purchasing a Dragster power amplier of the DDM series. Year by year the technology
designing car audio ampliers has grown a lot and DDM Series is the ulmate producon of Dragster range
aer more than 18 years from the DA and DB Series sll used from thousand of customers every day.
We consider top important to introduce the latest technologies oering you the absolute best sounding,
combined with powerful outputs of course at a reasonable price.
We strongly recommend that your Dragster power amplier be professionaly installed, this will ensure that
you will obtain the best possible performance from your amplier, improving reliability and safety for you
and your car.
• Thermal protecon: when the amplier reaches and unsafe operang temperature of 90 degrees
Celsius the amplier will turn o. Once the amplier cools down, simply reset the amplier by its remote
connecon (turn the amplier o and then on again once you have given the amplicator a change to cool
down) and the ampwill once gain begin.
• Speaker Short Circuit Protecon: should your speakers short circuit due to voice coil burn out, or should
the amplier sense an impedance too low to handle, the Protecon LED will light, indicang a diagnosc
condion. Turn o your system, disconnect one speaker at a me and try to determinate which speaker
might be faulty.
• Input Overload Protecon: the circuit will either shutdown the amplier completely, or make the
amplier spurt on and o indicang that it is in a diagnosc condion. Turn the system o and reduce the
gain on the amplier or volume from your head unit, this should result in a corrected condion.
• Bass Boost Control: Dedicated control for low frequency ranges (40 to 120Hz), allowing you to regulate
a desired frequency and control its gain (0 to + 12dB).
Read this manual carefully before installing the amplier. You must follow the instrucons for the product’s
installaon and connecons to guarantee opmal performance. If you have any quesons, get in touch
with us. Before using the amplier, always follow these guidelines:
▪ Make sure the appliance is switched o before adding or removing any connecons. This prevents
possible damage tothe equipment connected to the amplier;
▪ Keep all cables as far away as possible from the ignion cables, electronic injecon modules and starter
switch since they may cause noise interference;
▪ Always use good quality cables and connectors. This guarantees the sound’s quality and delity;
▪ To avoid damaging the cables, make sure that they do not touch sharp metal edges.
Important: Use recommended fuse 30 cenmeters from the baery as a safety precauon.
Introduction
Features
Before Installing
WARNING: Use of this amplier at extreme high volumes for extended periods of me may cause
hearing loss and hearig damage. High volume levels while driving will impair your ability to hear
necessary trac sounds. While driving always keep your sound volume at reasonable levels.

COOLER: The fans work when the device is turned on. They provide device cooling.
INPUT: This input should receive the signal through an RCA cable connected to the output of the
receiver or player.
OUTPUT: This output can be used oponally to play another amplier, facilitang installaon in mul-
amplied systems.
LEVEL: Controls the input signal level, allowing for proper control of any receiver or player. It can be
regulated as the following:
A) on the receiver or player, play any musical signal up to 80% volume.
(Ex: If the maximum volume on the player is 45 [100%], adjust to 36 [80%]).
B) on the amplier, beginning at the lowest LEVEL, gradually increase unl the LED “OVER CLIP”
begins to ash.
C) slowly decrease the LEVEL unl the LED “OVER CLIP” goes o.
L.P.F (LOW PASS FILTER): Controls the low pass point for the speaker outputs. It is regulated from
50Hz to 15KHz).
FREQUENCY (BASS BOOST): Adjustable control for boosng low frequency ranges from 40 to 120Hz.
GAIN (BASS BOOST): Gain adjustment control from 0 to +12dB at the frequency set at bass boost.
OVER CLIP (ON/OFF): With this key turned on, the LED “OVER CLIP” will light up at 15% more nal
capacity.

Installing the Input Cables
RECOMMENDED USE OF
AUXILIARY BATTERY.
Ground
FUSE
In order to install the power supply, Use the appropriate cable as specied for the model chosen. The
posive cable should come straight from the baery and have a fuse or protecve breaker 30 cm from the
baery. The negave cable should have the same gauge as the posive cable and be screwed to the chassis
of the vehicle, being careful to avoid paint and rust. These may interfere with the ow of the electrical
current and cause loss of power and interference in the sound.
REMOTE (REM)
SPEAKER (OUTPUT): This output is MONO. Be careful of maintaining the correct polarity of the
connecons between the speakers and check the minimum impedance of this output. Use cables with
minimum gauge as specied for the purchased model.
VENTS: Allows for the removal of warm air from the amplier. In model DDM5000.1, this opening has a fan.
POSITIVE POWER SUPPLY : Connect the terminal to the posive terminal of the baery (+12V).
It is extremely important that a protecve fuse or circuit breaker be used on this cable at a distance of
30 cm from the baery. The fuse or circuit breaker should be, at minimum, equal to the max current
consumpon value caused by playing musical signals (see technical specicaons table).
REM (REMOTE CONTROL): Connect the REM terminal to the electric antenna output of the receiver or
player. This will cause the amplier to turn on automacally when you turn on your receiver or player.
GROUND CONNECTION : Connect the cable to the chassis of the vehicle. Note: always connect the
wire of the player or other equipment to the same ground point.
CLIP LED (RED): This LED will light up when the signal begins to suer distoron.
PROT LED (RED): This LED will light up for the following reasons (see the diagnosc table on the back
cover):
A) Short circuit in the speakers C) Low baery voltage
B) Excessive temperature D) High baery voltage
POWER LED (BLUE): This indicator LED will light up when it is acvated by the remote control signal
from the receiver or player.

The speaker cables should be polarized (marked) so that you can easily idenfy which is posive and which
is negave. Keep the cables well insulated and avoid metal parts as these may damage the insulaon.
Check the minimum gauge of the installaon cables for your model.

NO POWER:
• The power cables are not connected correctly (terminals +BAT, GND and REM). Verify that all the
connecons have electrical and mechanical contact.
• The fuse/circuit breakers are defecve or blown. Replace them, making sure that the replacements are
the correct ones!
NO SOUND:
• The speaker cables or RCA plugs are not connected correctly.
• Verify that the LEVEL control is at the lowest seng. Check the amplier lter controls.
NO SOUND. RED ALERT PROT BLINKING:
• See “DIAGNOSTIC GUIDE”
• The speakers or cables are defecve, so check speakers, cables and connecons.
POOR SOUND QUALITY (DISTORTIONS):
• The speakers are overloaded. Decrease and readjust the volume level.
WEAK BASS:
• Speaker cables (+) and (-) are switched or the speaker is out of phase (see entry “INSTALLATION EXAMPLE
FOR SPEAKERS”). Also check BASS control adjustment.
ENGINE, HORN, TURN SIGNAL, INTERFERENCE:
• Use suppressing/insulated cables on the spark plugs.

• Use capacitors on the alternator, horn and ignion.
• Run the shielded input cable away from any other cables, as they are parcularly prone to interference.
• Install a separate power source (+12V) for the sound system. Use a fuse/circuit breaker 30 cenmeters
from the baery as the best precauon.
• Ground the amplier properly. Remove paint from the chassis at the selected point, and connect the
wire using a grounded terminal. In order to prevent rust, insulate it with paint.
Do not loop the ground. Avoid using mulple grounds. If possible, use a star connecon, in which all the
grounds run from a single point.
