C. Installation Procedure/Connections
Power/Protect Indicator:
If you feel unsure about installing this system yourself, have it installed by a
qualified technician.
Before installation Disconnect the NEGATIVE battery post connection and secure
the disconnected cable to prevent accidental reconnection during installation. This
is an essential safety precaution during installation!
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 induce noise into the audio system.
1. Connect the RED power lead to the positive (+12V) battery post.
There are two status indicator lights on the end panel of the amplifier.
1. “POWER” (Blue): Lights to indicate that the amplifier is turned on
and operating normally. 2. “PROTECT” (Red): Lights to indicate the
amplifier’s protection circuitry has been activated to prevent product
failure due to thermal overload, over current or short-circuit to the
amplifier’s outputs. When this protection mode is activated, the
amplifier will shut down to protect its circuitry. When the problem is
corrected, the amplifier will return to normal operation and the
“Protect” LED will shut off.
3. Fuse. Your NA2 already includes a 20A fuse. The NA2 power wires are 8’ long, while the
Fuse housing located on the Red/Positive power wire at 3.3’ of wire from the amplifier.
4. Connect the NR male controller DIN plug to the NA2’s female DIN plug.
* Powering the NA2 amplifier. Long pressing your NR controller’s power button for few
seconds will trigger both the NR controller and the NA2 amplifier ON/OFF.
5. Run the speakers wires to the amplifier’s output.
Make sure about correct polarity when connecting your speakers to the amplifier.
speaker’s Red wire (+) should connect to color (+) output channels.
speakers’s Black wire (-) should be connected to color / Black (-) output channels.
Speaker connection color codes:
6. If you haven t already done so, mount the amp now.
7. Now you should be good to go and play tunes for the first time.
2. We strongly recommend to run the Black/Ground power cable to the negative (-12V)
battery post.
Blue / Remote Turn-On wire is not required for installing or running your NA2
amplifier. The NR controller is able to power trigger your amplifier
You have plenty of power wire length before the fuse holder (3.3’). Strive to leave
no more than 18” (45.7 cm) of wire between the fuse holder and the battery
positive (+12V) terminal. You can cut the remaining wire.
