Installation Instructions

Before you start, disconnect the negative cable from the car battery. Tape up the end so it is isolated from the battery.
Run an appropriate gauge wire from the battery to the amplifier. Plan this part of the installation carefully. This cable will carry a very high current. If it should short to the body and it is not properly fused it could catch fire.
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 that 18 inches (wire length) from the battery you should reevaluate the wire and fuse placement.
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. It is advisable to test the ground with an ohm meter between the ground cable and the negative battery cable to insure a good low resistance connection.
Run the speaker wire to the speakers. Leave some extra wire at this point for adjustments later.
Mount the amp securely.
Connect the power and ground to the amplifier before installing the fuse at the battery.
Connect the remote wire from the head unit to the amplifier. Turn on the amp for the first time to ensure proper functionality.
Connect the speaker wires to the amp and speakers with correct polarity.
Connect the RCA cables to the amp.
Double check all amplifier controls to make sure everything is set correctly for your system.
Start playing audio with caution, gradually adjusting gain settings as needed.

FAQ

Q: How do I ensure a good ground connection for the amplifier?
A: Find a close clear metal area to the amp, remove any paint or undercoating, and securely screw in place. Test with an ohm meter for low resistance.
Q: When should I install the fuse in the power wire?
A: The fuse should be installed at the battery end after connecting all wires to prevent any potential issues during installation.
Q: What is the recommended initial setting for the gain control?
A: It is best to start with the gain control turned all the way down and gradually increase it while monitoring audio output for distortion.

You’re Headed in the Right Direction with NDA digital amps!

INTRODUCTION

The NVX / NDA digital amplifiers offer high quality audio reproduction for the audiophile and the everyday listener, alike. All models feature fully variable crossovers with 12 dB per octave slopes, allowing you the ability to tailor the sound to best fit the speakers and your listening preferences.
Platinum finish connections Ensures solid electrical connections that resist corrosion.
Fully Variable Crossovers 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.
Protection Circuitry Against Overload, Short Circuit, Thermal, Low Voltage, High Voltage, and Reverse Polarity. These protection features are designed to protect the amplifier from misuse, as well as from common causes of amplifier failure.

INSTALLATION

Professional installation by an authorized NVX 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 trucks. Select a location that will provide adequate ventilation for the amplifier. Avoid mounting the amplifier with the fins facing down. The fins should be facing up, either vertically or horizontally. Secure the amplifier with the screws provided.

INPUT
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.
Input Section
Because of the wide range of head unit output configurations all NDA digital 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 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. We recommend using oscilloscope when setting input gains on amplifiers to make sure you have clean round sound waves. For example, if you have 5 volts coming from source unit, most likely amplifier gain will be set properly with one or two clicks from the bottom. If you have 1 volt coming into amplifier your gain most likely will be ¾ turn.

CROSSOVER CONTROLS
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 is needed to ensure that all of the speakers are playing the right sounds and that you are left with no nulls” or low spots in the frequency response. You will need to know what frequency response range on your speakers to determine crossover points.

SPEAKER OUTPUTS
This amplifier is a multi-channel amplifier design. Meaning it has more than one channel of speaker outputs. It 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. Know your total ohm load before you make any connections.

INSTALLATION INSTRUCTIONS

Before you start, disconnect the negative cable from the car battery. Tape up the end so it is isolated from the battery.
Run an appropriate gauge wire from the battery to the amplifier. Plan this part of the installation carefully. This cable will carry a very high current. If it should short to the body and it is not properly fused it could catch fire.
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 that 18 inches (wire length) from the battery you should reevaluate the wire and fuse placement.
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. It is advisable to test the ground with an ohm meter between the ground cable and the negative battery cable to insure a good low resistance connection. Some alloys used in modern cars do not offer the best ground. If you believe this is the case, consult with the vehicle manufacturer.
Run the speaker wire to the speakers. It is advised that you leave some extra wire at this point. You can “clean it up” later.
If you haven’t already done so, mount the amp now. Connect the power and ground to the amplifier.
Only after this step should you install the fuse at the battery.
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.
Connect the speaker wires to the amp and speakers (make sure the amp is off first). Make sure the polarity(+add-) is correct.
Connect the RCA’S to the amp.
Double check the amplifier controls at this time. Make sure everything is set correctly for your system.
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,
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 re-charge it if it gets low.

Now you’re ready to experience music in its purest form. We are NVX… engineered for sound.
