INSTALLATION
Preparation
Please read entire manual before installation. Due to the technical nature of
amplifiers, it is highly recommended that your Axxera amplifier is installed by a
professional installer or an authorized dealer.
Before You Start
• Disconnect negative battery terminal. (consult a qualified technician for
instructions)
• Avoid installing the amplifier where it would be subject to high temperatures, such
as from direct sunlight, or where it would be subject to dust, dirt or excessive
vibration.
• Use extreme caution when drilling holes to avoid damaging fuel lines or existing
vehicle wiring.
• All amplifier installations require power, signal and speaker wires (not included).
• An amplifier installation kit (sold separately) is highly recommended to facilitate
the installation. Consult your dealer for recommendations.
Mounting Location
• Choose a mounting location for the amplifier. Suggested locations include under a
seat or in the trunk.
• The amplifier can be mounted horizontal (recommended) or vertical. For optimum
performance, make sure to provide at least 1" of space around all sides. Do not
mount the amplifier under carpets or where airflow is restricted.
• Do not install the amplifier where it may be exposed to moisture.
• The optimum mounting location varies between vehicles. Remember to test all
amplifier functions before completing the final mounting procedure.

INSTALLATION
Connection Descriptions
NOTE:
Be sure to follow specific instructions included with your amplifier installation kit
(not included with this amplifier). The information below should be used as a general
guideline only.
Power Wire (+12V)
• Disconnect negative battery terminal before proceeding. Consult a qualified
technician for instructions if you are unsure.
• Plan wire routing before cutting any wires to length. Begin by routing the power
+12V wire from the battery to the amplifier location. Use a grommet when running
wires through the firewall or metal openings. Avoid running the power wire near
existing vehicle wiring to prevent induced noise from entering the audio system.
• Use extreme caution when drilling holes to avoid damaging fuel lines or existing
vehicle wiring.
• The +12V wire MUST be fused within 18" of the battery for protection of the vehicle’s
electrical system.
Ground Wire (GND)
• The amplifier ground wire should be as short as possible (no more than 36" or
1 meter). Choose a clean unpainted section of metal or the vehicle chassis when
attaching the ground connection. Be sure to clean the area of any dirt or grease.
Remote Turn-on Wire (REM)
• The remote turn-on wire connects to the head unit's amplifier turn-on lead or
power antenna output.
Speaker Wires
• Choose adequate gauge speaker wire depending on your exact amplifier/speaker
combination. Be sure to observe polarity when connecting.
• Do not ground any speaker wires or connect any speaker wires together.
Input Signal
• The amplifier's input signal connects to the head unit's low level (RCA) or high level
(speaker wire) outputs.
• Low level input signals deliver the best performance. If unavailable, use the high
level inputs - when interfacing with factory head unit for instance.
CAUTION
• Do not use both low and high level inputs at the same time. Connect only one or the
other.
• Keep low level inputs away from any power wires to avoid engine noise.
• Never run any wires underneath or outside the vehicle.
