A. Installation Applications:
The NUTV5 / NUTV5-S is designed for operation with 12 volts, negative-ground electrical
systems. Using this product in systems with positive ground and/or voltages other than
12V may result in damage to the product and will void the warranty.
B. Safety Considerations:
C. Battery and charging:
• Though this is a Marine IPX6 rated amplifier, whenever possible, mount the amplifier in a dry,
well-ventilated location that does not interfere with other factory installed electronic devices.
If a dry environment is not available, a location that is not exposed to heavy splashing may be
used.
• While this amplifier is designed to be water-resistant, it should never be submerged under
water or subjected to high-pressure water spray. Do not install where it will be directly
exposed to the elements.
reasons you might want to re-tune and readjust it. 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 recharge it if it gets low.
Amplifiers will put an increased load on the vehicle’s battery and charging system.
We recommend checking your alternator and battery condition to ensure that the
electrical system has enough capacity to handle the increased load of your stereo
system. Stock electrical systems which are in good condition should be able to
handle the extra load of the NA4 amplifier without problems, although battery and
alternator life can be reduced slightly. To maximize the performance of your amplifier,
we suggest the use of a heavy-duty battery and an energy storage capacitor
• Securely mount the amplifier so that it does not come loose in the event of a
collision/sudden jolt or as a result of repeated vibrations during normal operation.
• Check before drilling to make sure that you will not be drilling into an exterior panel/hull,
fuel tank, gas/brake line, wiring harness, or other vital system.
Heaving an amplifier sealed to the elements at IPX6 level means that
heat generated inside the amp has nowhere to escape. Playing hard with
your NA4 will get it Hot. That’s fine and normal. But, avoid touching the
amplifier’s surface during or right after use.
Do not mount the amplifier in the engine compartment or in any areas of extreme heat.
Mounting the unit in the engine compartment will void your warranty.
• Protect all system wires from sharp edges (metal, fiberglass, etc.) by carefully routing
them, tying them down and using grommets and loom where appropriate.
• Secure all wiring as needed, using cable ties or wire clamps to protect them from
moving parts and sharp edges.
Do not run system wiring outside or underneath the vehicle/vessel. This is an
extremely dangerous practice, which can result in severe damage/injury.
More about the NA4 Amplifier
Get to know your NA4
The NA4 amplifier is state of the art Class D amplifier designed to
audio system. The NA4 is a 4-channel full range amplifier with fully
variable high pass and low pass crossovers enabling it to drive a wide
variety of either full range speakers or subwoofers.
The NA4 amplifier is meant to work with the NOAM NR Bluetooth
controller. The NR controller is your audio source head-unit, able to
trigger your amplifier ON/OFF.
