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.
TYPICAL MOUNTING METHOD

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.

Speaker Connections
Connect speaker wires
observing polarity. The
minimum impedance load for
the AX460D and AX490D is
2 ohms stereo and 2ohms
bridged. Use of loads lower than
these is not recommended and
may cause amplifier damage.
The AX460D and AX490D can
be wired for stereo, bridged or
stereo/bridged simultaneous
operation.
Input Signal Connections
Low Level Input (RCA)
Low level (RCA) input signal is preferred for best performance. Typical trunk-mount
amplifier installations require a 17-20 foot RCA cable. Most trucks and under-seat
applications require a 6-9 foot RCA cable. Using twisted pair construction RCA
cables will minimize noise.
High Level Input
(Speaker Wire)
High level inputs should only be used
when RCA outputs are not available
from the head unit. Connect the
head unit speaker outputs to
the high level input connector
as shown below. The black wire
(signal reference ground) may or
may not require a connection to
chassis ground - depending on your
particular installation.

Note: Do not use both low and high level inputs
