- This equipment is for use in automotive DC voltage batteries between 12.6 and 14.4 volts. Before installing the equipment, check voltage of the batteries;
- Do not install the amplifier in places exposed to water, dirt or humidity;
- Choose a ventilated place to install the amplifier and avoid blocking the side ventilation windows;
- Mount the amplifier in a secure way. Avoid mounting it on metallic parts of the vehicle, because it may cause ground looping (noise);
- Make sure that the location chosen for the amplifier installation does not effect the operation of the vehicle;
- When passing cables through metallic walls, use rubber O-rings to avoid cable cutting and short-circuits.
- Clean the amplifier periodically with brush or dry cloth to assure the thermal efficiency of the heatsink.
- This product may reach temperatures over 60°C/140°F. Make sure it is cold before touching it;
- Be careful when making holes in the vehicle. Make sure you are not making holes in the fuel tank, brake lines or electrical cables of the vehicle
- Make sure the cables are properly secured throughout the installation;
- Wear gloves, safety glasses and and all necessary PPE during the installation of SounDigital amplifiers.
Warning
THIS “WARNING” SIGN ALERTS THE USER OF IMPORTANT INFO. NOT FOLLOWING THIS
INSTRUCTIONS MAY CAUSE INJURIES TO THE USER OR DAMAGE TO THE EQUIPMENT.
TECHNOLOGIES
DYNAMIC THERMAL MANAGEMENT – DTM®
OUR PATENTED DTM* TECHNOLOGY PROVIDES A FASTER HEAT EXCHANGE BETWEEN THE ELECTRONIC COMPONENTS AND THE HEATSINK, INCREASING THE EFFICIENCY OF OUR AMPLIFIERS AND RESULTING IN LOWER DISTORTION LEVELS DURING LONG PLAYING TIME.
VIBRATION ABSORPTION DEVICE – VAD®
OUR VAD* TECHNOLOGY REDUCES ALL IMPACT CAUSED Y VIBRATION ON THE ELECTRONIC CIRCUIT BOARD. THIS CAN INCLUDE ROAD VIBRATION AND EVEN VIBRATION CAUSED BY SOUND WAVES, INCREASING THE RELIABILITY OF OUR AMPLIFIERS.
REDUCED SIZE
THE TECHNOLOGY USED IN OUR AMPLIFIERS BRING BOTH HIGH PERFORMANCE AND POWER IN A COMPACT CHASSIS, PROVIDING FLEXIBLE INSTALLATION SOLUTIONS FOR VEHICLES WITH LIMITED SPACE.
FULL RANGE
VERSATILE PRODUCTS THAT COVER THE ENTIRE AUDIBLE FREQUENCY RANGE, ANY TYPE OF LOUDSPEAKER OR MUSIC PROGRAM.
ASSEMBLING AND DISASSEMBLING THE PLASTIC COVER
The plastic covers have the function of finishing and hiding the amplifier fixing screws. To disassembling and assembling them, follow the instructions below.
DISASSEMBLING OF THE PLASTIC COVER
- Carefully pull out the top of plastic cover to release the upside latches, as shown in the picture 1.
- Slide up the plastic cover in a continuous movement to remove it.
ASSEMBLING THE PLASTIC COVER
- To fit the plastic cover back, carefully insert the point A of the plastic cover into point B of the amplifier, slowly sliding it down.
- Gently press the sides of the top of the plastic cover towards the bottom of the amplifier until you hear a clicking noise.

ELECTRICAL DIMENSIONING AND AUDIO INPUTS
ELECTRICAL DIMENSIONING
For proper operation of your SounDigital amplifier, you need the proper dimensioning of the electrical system and the cables used.
The table below shows the minimum section of GND cables, +12VDC cables and speaker output cables according to the power generated by the ampilifier.
2400 WRMS| POWER CABLE
GROUND CABLE| 21mm² – 4 AWG
---|---|---
SPEAKER CABLE| 2 x 2mm² – 12 AWG
We recommend the use of ONLY OFC (Oxygen Free Copper) Cables on the installation of our products.
AUDIO INPUTS
RCA Inputs
High signal inputs
High input must be used when the main unit does not have RCA outputs.
When hi inputs is used, no remote connection is required, the amplifier recognizes the audio signal and switches on.
If your source unit is not able to turn on the amplifier through the high level input, the remote input should be connected normally.
Warning
RCA AND HIGH INPUTS SHOULD NOT BE USED SIMULTANEOUSLY OR YOU MAY DAMAGE THE
AMPLIFIER.
INSTALLATION SEQUENCE
Warning!
BEFORE PROCEEDING WITH THE INSTALLATION, UNPLUG THE NEGATIVE TERMINAL FROM ALL
OF THE BATTERIES, TO AVOID FIRE, DAMAGE TO THE AMPLIFIER AND THE USER HIMSELF.
-
Mount the amplifier in such a way you have access to the connectors;
-
Install the power cables in the vehicle properly, starting from the battery to the fuse holder or circuit breaker, use the cable with the appropriate size. Make all connections, install fuse holders or circuit breakers, but without placing the fuses or with the circuit breakers in the “Off” position.
Warning!
THE MAX. DISTANCE FOR THE INSTALLATION OF THE FUSE/CIRCUIT BREAKER IS – ONE FOOT (30 CM) AWAY FROM THE BATTERY. -
Connect 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 batteries to the negative connector of the amplifier;
-
The ground cable must be as short as possible and must be connected to the vehicle chassis and the battery negative;
-
Install the signal input cables in a proper way, distant from the power cables;
-
Connect the RCA or the high signal input cables to the head unit and amplifiers;
-
Install the audio output cables with the appropriate section , distant from the power and audio input cables;
-
Connect the audio output cables to the amplifier and speakers respecting the positive (+) and negative (-) polarities;
-
Install the remote cable with the power cables, using 1.5mm2 (15 AWG) cable or thicker;
-
Connectthe remote power cable to the amplifier’s “REM” terminal at the main unit’s remote power output (when not using the high level signal inputs);
-
Before powering the system, verify all the connections and make sure there are no mistakes or short-circuits on the power and ground cables;
-
Reconnect the ground of the batteries;
-
Check if the head unit is turned off and then place the fuses in the fuse holders or switch the circuit breakers on;
-
Turn on the main unit and the amplifier will turn on the “On” LED indicating that it is in operation.

GAIN SETING
Necessary equipament:
- Digital AC voltmeter;
- Media with sine wave test tone 60Hz recorded at Odb;
- Screwdriver 1/8″(for gain set)
Set up procedure
- This procedure is the same for both gain controls;
- Turn the gain control all the way down.
- Disconnect the output cables from the amplifier outputs;
- Turn off all processing (bass, treble, loudness, EQ, etc.);
- Set the source unit volume to 3/4 of full volume.
- Set the source unit’s fader control to center position;
- Set the crossover selector switch in “F”
- Usea60Hzsinewave
- Connect the AC voltmeter to the speaker output connectors of the amplifier. Make sure you test the voltage at the correct connectors (+ and-);
- Increase the gain control until the target voltage is observed with the voltmeter (see the chartbelow);
- Once you have adjusted the amplifier to its correct voltage output, turn off the source unit and reconnect the speaker(s)
