WARNING: Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing
loss. Diamond Audio amplifiers can exceed that level so please exercise restraint when listening and enjoying
your new amplifier.
GENERAL PRECAUTIONS
This unit is designed for negative ground 12V DC operation only. (some older english vehicles have a
positive ground!)
Total system impedance must not be less than 2 ohm, in a bridged OR stereo configuration (monoblocks are
1 ohm stable)
Avoid installing the unit where:
- It would be subject to high temperatures, such as from direct sunlight or hot air from the heater.
- It would be exposed to rain or moisture.
- It would be subject to dust or dirt.
Do not cover the amplifier with carpet or wires.
Do not use the amplifier with a weak car battery. Optimum performance depends on a normal battery supply
voltage.
For safety reasons, keep the volume of your car audio system moderate while driving your vehicle so that
you can still hear normal traffic sounds and emergency vehicles outside your car.
MOUNTING PRECAUTIONS
Although Diamond Audio NEO amplifiers incorporate heat sinks and protection circuits, mounting the amplifier
in a tight space without any air movement can still damage internal circuitry over time. Choose a location that
provides adequate ventilation around the amplifier. For easy system set-up, mount the amplifier so the side
panel controls will be accessible after installation. To increase thermal run times on low impedance loads, an
additional fan is recommended, remember any moving air across the amplifier will reduce heat. In addition,
observe the following precautions:
1. Using a felt pen mark, mark the mounting hole locations.
2. Mounting the amplifier on carpet will significantly reduce air flow, resulting in reduced thermal run times.
3. Mount the amplifier on a solid surface. Avoid mounting to sub woofer enclosures or areas prone to vibration.
Do not install the amplifier on plastic or other combustible materials.
4. Prior to mounting the amplifier, make sure not to cut or drill into the fuel tank, fuel lines, brake lines (under
chassis) or electrical wiring.
WIRING PRECAUTIONS
1. Before installation, make sure the source unit power switch is in the OFF position.
2. Disconnect the negative (-) lead of the battery before making any power connections.
3. When making connections, be sure that each one is clean and secure. Insulate all of your connections.
Failure to do so may damage your equipment.
4. A secure clean ground connection is critical to the performance of your amplifier. Connect the ground directly
to the car chassis to minimize resistance and avoid any noise problems.
5. Add an external fuse on the amplifier's positive (+) power lead and connect it as close as possible to the
vehicle's (+) battery terminal. 18 inches is the usual dimension. Use a rating that equals the total current
consumption at full output of all amplifiers in the system. This external fuse will protect the vehicle from short
circuits that can cause a fire.

WIRING INSTALLTION
VEHICLE ELECTRICAL SYSTEM
Amplifiers (regardless of brand name) will put an increased load on the vehicle's battery and charging system.
Diamond Audio recommends checking your alternator and battery condition to ensure that the electrical system
has enough capacity to handle the increased load of your stereo system. Original equipment electrical systems
which are in good condition should be able to handle the extra load of any NEO amplifier without problems,
although battery and alternator life can be reduced depending on your individual listening habits. To maximize
the performance of your amplifier, we suggest the use of a reserve power "Stiffening"capacitor (1 Farad per
1000W).
WARNING:
Avoid running power wires near the low level input cables, antenna, power leads, sensitive equipment or
harnesses. The power wires carry substantial current and could radiate noise into the audio system through
the audio cables.
1. Plan the wire routing as described in the "Importance of Pre-Planning" section. Keep RCA cables close
together but isolated from the amplifier's power cables and any high power auto accessories, especially
electric motors. This is done to prevent coupling the noise from radiated electrical fields into the audio
signal. When feeding the wires through the firewall or any metal barrier, protect them with plastic or rubber
grommets to prevent short circuits. Leave the wires long at this point to adjust for a precise fit at a later time.
2. Prepare the power wire for attachment to the amplifier by stripping 5/8 inch (15.9mm) of insulation from the
end of the wire. Insert the bare wire into the B+ terminal And tighten the set screw to secure the cable in
place.
WARNING:
The B+ cable MUST be fused 18" or less from the vehicle's positive battery post. Choose a location to install a
waterproof fuseholder under the hood and ensure connections are water tight. If you do not use the appropriate
fuseholder, the connection will eventually suffer corrosion from moisture and heat.
3. Trim the power cable within 18 inches (45.7mm)
of the positive battery post and splice an in-line
fuse holder. DO NOT install the fuse at this time.
4. Strip 1/2 inch (12.7mm) from the battery end of
the power cable. Crimp and soldier a large ring
terminal to the cable. Connect the ring terminal
to the positive (+) battery post.
NEO15006DSP
NEO15006DSP
Prepare the ground wire for attachment to the amplifier by stripping 5/8" of insulation from the end of
the wire. Always use a wire of the same gauge as the power connection, never smaller. Insert the
bare wire into the GND terminal and tighten the set screw to secure the cable in place. Prepare the
chassis ground by scraping any paint from the metal surface and thoroughly clean the area of all dirt
and grease. Strip the other end of the wire, crimp and soldier a ring connector.
Fasten the cable to the chassis using a non-anodized screw with a star washer.

WARNING: It is important to upgrade the ground
connection between the negative (-) battery post and
the vehicle body or chassis to achieve optimum
electrical performance.
Prepare the REM turn-on wire for attachment to the
amplifier by stripping 5/8 inch (15.9mm) of insulation
from the end of the wire. Insert the bare wire into the
REM terminal and tighten the set screw to secure the
wire in place. Connect the other end of the REM wire
to a switched 12 volt positive source. The switched
voltage is usually taken from the source unit's remote
amp turn on lead. If the source unit does not have this
output available, the recommended solution is to wire
to an accessory terminal in the car's fuse block using
a relay to isolate the amplifer from the vehicles
accessory circuit. This however will turn the amplifier
on and off with the ignition key, regardless of whether
the car stereo is on or off.
Securely mount the amplifier to the vehicle or amp rack. Be careful not to mount the amplifier on
cardboard or plastic panels. Doing so may enable the screws to pull out from the panel due to road
vibration or sudden vehicle stops.
Connect from source signal by connecting the RCA audio cables (or speaker wires) to the input jacks at
the amplifier.
Connect the car speakers. Speakers impedance should NEVER be less than 2 Ohms stereo, 4 Ohms
bridged(the mono block's are stable into 1 ohms). For most applications 18 gauge wire is adequate for the
speaker leads. For leads in excess of ten feet, 16 gauge wire is recommended. Strip the speaker wires 1/2"
(12.7mm) and insert into the speaker terminal block, then tighten the set screw to secure into place. When
wiring the speakers, pay careful attention to the polarity of the terminals on the speakers and make certain
they correspond to the polarity on the amplifier. DO NOT chassis ground any of the speaker leads as
unstable operation or damage to the amplifier and/or speaker may result.

INPUT LOAD
Matches the output impedance of the front-end audio source, preventing signal reflection, distortion, or
abnormal volume, and ensuring optimal audio signal transmission efficiency and sound quality.
5
POWER INPUT
These connections are for input power, chassis ground, and remote turn-on. Use a minimum of 8 gauge
wiring for power and ground connections. 4 Guage is recommended for the monoblock. The terminals
will handle up to 4 gauge wiring with no problem whatsoever. Be sure any wiring that passes through
metal has a grommet! DO NOT USE CCA power/ground wire !!
6
SPEAKER OUTPUT
Connect your speakers to these terminals. Stereo connections are connected as labeled. Bridged
connections use the LEFT + and RIGHT - as the two connections. The 2 and 4 channel amplifiers will
perform into 4 and 2 ohm stereo loads or 4 ohm bridged loads. DO NOT run 2 ohm bridged loads on
these amplifiers! The mono blocks will run 1 ohm mono.
