SAFETY PRECAUTIONS

Fuse amplifiers power wire at the battery
Be sure to fuse the power wire within 17 of the car’s battery. This will protect the car’s battery in case of a short circuit between the power amplifier and battery. THIS IS A MUST, the amplifier’s built-in fuse will only protect the power amplifier not the car’s battery!
Use high-grade wire connectors
To ensure maximum power transfer and secure safe connections, it is recommended to use high-grade barrier spades (for connection at amplifier) and terminal rings (for connection at the battery).
Do not run any wires underneath the vehicle
Exposed wires have a chance of being cut or damaged. It is best to run all wires through the vehicle under the carpet and/or side panels. This lends to a cleaner installation and less risk of damage.
Use caution when mounting the amplifier
Remember there are many electrical wires, gas lines, vacuum lines, brake lines as well as a gas tank in the automobile. Make sure you now where they are when mounting the amplifier to avoid puncturing lines, shorting wires or drilling holes in the gas tank.
Run signal wires away from electrical wire s
To avoid the possibility of induced noise from the car’s electrical system (i.e. popping noises or engine noise), run wires away from the car’s electrical wiring.
Make all ground wires as short as possible and at the same point
In order to reduce the chance of ground loops (i.e. engine noise), make the grounding wire as short as possible to reduce the wire’s resistance. Also, when using multiple components, make sure all units are grounded at the same point.
Avoid sharp edges when running the wires
To avoid the possibility of power, signal, or speaker shorts, be careful not to allow the amplifiers wires to come in contact with sharp edges. Use a grommet to protect the wire when running through the firewall.

FEATURES AND BENEFITS

DC Offset Protection
This circuit protects the output of the amplifier against DC voltage. If for some reason DC voltage is detected at the output stage, the amplifier will shut down protecting the speakers from direct current.
Short Circuit Protection
The circuit protects the amplifier from damage due to a short found in the speakers or wiring. If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down. To resume normal operation, correct the problem and turn the head unit off, then back on. The amplifier will reset and play again.
Thermal Protection
To protect the amplifier circuitry against damage caused by prolonged exposure to high temperatures, a thermal protection circuit is activated if the amplifier reaches excessively high operating temperature. Once the thermal circuit is activated, the amplifier will shut down to cool off. The amplifier will automatically turn back on once it cools down to a safe operating temperature.
Power Indicator
The diagnostic L.E.D. illuminates when the amplifier is on and receiving power.
Built-in Crossover
The NEO amplifiers include built-in variable crossovers. The crossover features a variable frequency selection for precise low pass filtering for the NEO1.5Kv2. The NEO4v2 and NEO5v2 also feature the same frequency selection with the option of high pass or low pass filtering.
Power and Speaker Distribution Blocks
Heavy gauge bare wire distribution blocks are provided for maximum power and signal transfer with minimal resistance.
Bass Boost (NE01.5Kv2) (NEO5v2)
For added low-frequency performance the amplifiers are equipped with a variable ‘0-12 dB bass boost @ 45Hz.
Power Fusing
This protects the amplifier against short circuits and excessive current. NEO4v2 – 60 Amp NEO5v2 – 70 Amp NEO1.5Kv2 – 80 Amp
Remote Turn-on
Automatically turns the amplifier on when connected to the head unit’s remote output. The amplifier will turn on and off with the head unit to save current consumption. This control also operates the reset circuit for the amplifier’s protection. It must be connected with the head unit in order to reset protection circuits.
Adjustable Input Sensitivity
Allows you to fine-tune the level matching between your source and the power amplifier.
Low Impedance Stability
NEO4v2 – 2Ohm Stereo
NEO5v2 – 2Ohm Stereo
NE01.5Kv2 – 10hm Mono

MOUNTING LOCATION

Before you start the installation, it will be necessary to find a mounting location for the amplifier. Find a location in which the amplifier will receive adequate ventilation in order to dissipate the heat it develops during operation. Two popular mounting locations are in the trunk or under the seat.
Select the location in which you wish to mount the amplifier. Use caution when mounting amplifiers, there are many wires, gas lines, vacuum lines, brake lines as well as a gas tanks in the automobile. Make sure you know where they are when mounting the amplifier to avoid puncturing lines, shorting wires or drilling holes in the gas tank. Once you are ready, use a pencil to mark the mounting holes in the bottom panel. After you have marked the locations of the holes move the amplifier out of the way and drill small starter holes to make the tapping screws easier to install. Use provided screws to tighten down the amplifier.

Power connections

IMPORTANT! Before making any connections, disconnect the car’s battery until the installation is completed to avoid possible damage to the electrical system.
Connect the amplifier to the car’s battery
At times, the amplifier will need to draw large levels of current that cannot be provided by any circuit in the car’s fuse box. We recommended using a 4 to 8 gauge power wire for your connections depending on the amplifier and length of the wire. Strip one end of the wire to connect to the terminal on the amplifier marked “batt+’. Loosen screw terminal and connect bare wire and tighten. Use caution to make sure no stray wire strands come in contact with surrounding terminals causing short circuits. Run the wire directly to the positive terminal of the car’s battery. Make sure to use an in-line fuse within 12′ of the car’s battery to protect the electrical system and amplifier against short circuits and/or power surges.
Connect the ground terminal of the amplifier to the car’s chassis
For the ground connection, use a 4 to 8 gauge wire (black) to connect to the terminal marked ‘ground’ and then connect it to the car’s chassis. Try to keep the length of the cable as short as possible, preferably less than 6′. Also, make sure that the point on the car where the connection is to be made is free of paint and dirt.
Connect the remote terminal of the amplifier to a switchable +12V source
This connection allows the amplifier to be turned on and off with the power control of the radio. If the radio has a REMOTE output terminal, connect it to the amplifier’s terminal marked ‘remote” (using a 16 gauge wire or heavier). Now when the radio is turned on, the amplifier will automatically turn on. This connection can also be made to the radio’s Power Antenna wire.

SIGNAL CONNECTIONS

Connect the RCA output of the head unit (AM/FM cassette player, CD, or DAT) to the RCA input terminals of the amplifier.
To make these connections, we recommend high-quality RCA cables, which are available at your local car audio retailer. Run signal wires away from electrical wires to avoid the possibility of induced noise from the car’s electrical system (i.e. popping noises or engine noise).

SPEAKER CONNECTIONS

IMPORTANT! The following speaker connection is for the amplifier in normal mono configuration.
Make the speaker connections using a speaker wire that is at least 16 gauge or heavier.
As with any audio component, proper phasing of the amplifier and speakers is essential for a strong bass response. When connecting, make sure that positive (+) from the amplifier is connected to the positive (+) of the speaker, and the same for negative (-).

TROUBLESHOOTING THE SYSTEM
we have put together this troubleshooting guide if you experience problems after installing the amplifier. Please keep in mind that the majority of problems incurred are caused by improper installation and not the equipment itself. In addition, there are many components in the system that could cause various signal problems such as inducted electrical noise and engine noise.
Before you can properly address the problem, you must first find the component that is causing the problem. This will take patience and a process of elimination.
