ØIf you have questions about the installation of this
equipment, get in touch with our tech support or with a
professional specialized in car audio installation;
ØBefore proceeding with the installation of any electric
equipment on your vehicle, unplug the negative (-) terminal of
the battery to avoid fires, injuries or damages;
ØUse your sound system safely, exposure to continuous
sound pressure over 85dB may cause irreversible hearing
loss.
ØDo not install the amplifier in places exposed to water, dirt
or humidity;
ØTo prevent injuries to the user or damage to the amplifier,
read all the safety instructions written on this manual;
ØThis equipment is for use in automotive DC voltage
batt er ie s, be tw ee n 1 2. 6 a nd 14 .4 vo lt s. B e f o r e
installing the equipment, check the voltage of the
batteries;
ØSecurely mount the amplifier so that it does not come loose
in the event of collision or a suddent jolt to the vehicle. Avoid
mounting it on mettalicparts of the vehicle, because it may
cause an ground loop (you might have noise issues).
SAFETY INSTRUCTIONS
Congratulations on acquiring a product with the highest
quality and technology!
The SounDigital products are developed to assure
maximum efficiency and reability to your sound system.
Dear Customer,
The main characteristics of Class D amplifiers are: audio
quality, efficiency, versatility and compact design. Here are
the advantages of these characteristics:
Class D Amplifiers:
Audio Quality – Class D amplifiers used to have a limited
response in the past and they used to have a worse
performance regarding higher frequencies than Class AB
amps, despite being more efficient. Introducing new
technologies, SounDigital developed a Class D amplifier
superior to the Class AB ones in efficiency and performance.
Efficiency – The SounDigital Class D amplifiers have a total
efficiency (power source + output) higher than 60%, assuring
a battery consumption and a heating lower than the expected.
Versatility of Uses –The flat response of all the frequencies
of SounDigital amplifiers allows them to be used in all the
kinds of systems: SPL, Sound Quality, Trio Eletrico and
Pancadao, meeting the needs with extreme quality.
Compact Design – The high efficiency and technology allow
our amplifiers to be really compact, making it easy to install
them in vehicles where you have limited space.
IMPORTANT INFO
Read this manual and follow its instructions and information
carefully. It contains extremely important information to have
your amplifier working properly. If you feel the need to contact our
Tech Support, you can reach our technicians through the e-mail
[e-mail].
IMPORTANT INFO
To know our complete line of amplifiers and accessories, visit
www.soundigitalusa.com.
We recommend the use of SounDigital original accessories
for a better performance. The crossovers and voltmeters
offered by SounDigital follow the same quality standards as
our amplifiers, assuring an excellent quality and high power
sound system to our customers.
This “Warning” sign alerts the user of
important info. Not following this
instructions may cause injuries to the user
or damage to the equipment.
Warning!

ØWhen passing cables through metallic walls, use rubber O-
rings to avoid cable cutting and short circuits.-
ØMake sure the place chosen for the installation of the
amplifier will not interfere with the proper working of the
vehicle;
ØClean the amplifier periodically with a brush or dry cloth to
assure the thermal efficiency of the heatsink;
ØBe careful when making holes in the vehicle. Make sure
you're not making holes in the fuel tank, br ake lines or e
electrical cables of the vehicle;
ØMake sure the cables are properly fixed throughout the
ins allationt ;
ØWear gloves, safety g s and all necessary PPE during lasse
the installation of SounDigital amplifiers.
ØBefore proceding with the installation, unplug the negative
from all of the batteries;
Installation Sequence
ØMount the amplifier in such a way you have access to the
connectors;
ØThis product may reach temperatures over 60°C/140°F.
Make sure it is cold before touching it;
ØInstall the power cables on the vehicle in a proper way.
From the battery to the bussbar, fuse holder or circuit breaker.
Chose the appropriate size for the cable (see Technical Specs
Table ). Make all of the connections to the bussbars, fuse
holders or circuit breakers, with no fuses installed and with the
circuit breakers in the "Off" position;
ØConnect the audio output cables to the amplifiers and the
acoustic boxes, observing the positive (+) and negative (-)
polarities;
ØInstall the signal input cables in a proper way, distant from
the power cables;
ØConnect the power cables in to the amplifier, observing the
polarity. Connect all the positive cables from the fuse holder or
circuit breaker to the positive conector of the amplifier and all
the negative power cables from the bussbar or from the
batteries, to the negative connector of the amplifier;
ØConnect the remote cable to the REM terminal on the
amplifier and to a 12V power supply activated by a switch key
or to the remote power output of the head unit;
ØInstall the remote cable with the power cables, using a
section of 15 AWG (1.5mm²) or thicker;
ØBefore powering the system, verify all the connections and
make sure there are no mistakes or short-circuits on the
power and ground cables;
ØReconnect the ground of the batteries;
ØInstall the audio output cables with the appropriate section ,
distant from the power and audio input cables;
ØCheck if the remote key is in the "Off" position and if the
head unit is turned off, then place the fuses in the fuse holders
or switch the circuit breakers on.
ØConnect the RCA to the head unit and amplifiers;
The max. distance for the installation of the
fuse/circuit breaker is one foot away from the
battery.

ØHigh input must be used when the main unit does not have
RCA outputs.
ØWhen high inputs is used, no remote connection is
required, the amplifier recognizes the audio signal and
switches on.
ØIf your source unit is not able to turn on the amplifier through
the high level input, the remote input should be connected
normally.
RCA and hi inputs should not be used
simultaneously or you may damage the
amplifier.

PROCEDURES FOR SETTING THE GAIN
Necessary equipament:
Ø Turn the gain control all the way down.
Set up procedure
ØDisconnect the output cables from the amplifier outputs;
ØTurn off all processing (bass, treble, loudness, EQ, etc.);
ØMedia with sine wave test tone (60Hz) recorded at 0db;
ØSet the source unit volume to 3/4 of full volume.
ØSet the crossover switch to "Full" or "F" and play a 60 Hz
sine wave test track;
ØOnce you have adjusted the amplifier to its correct voltage
output, turn off the source unit and reconnect the speaker(s).
ØIncrease the “Input Sens.” control until the target voltage is
observed with the voltmeter (see the chart to the right);
ØConnect the AC voltmeter to the speaker output connectors
of the amplifier. Make sure you test the voltage at the correct
connectors (+ and –);
