XIA3145 INSTALLATION
Preparation
Please read entire manual before installation. Due to the technical nature of amplifiers,
it is highly recommended that your DUAL 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 to 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.

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 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. 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.
Illuminite Circuit (12VDC Output - for DUAL illuminite speakers only)
• Use 18-gauge or larger wire for making the connections to the illuminite terminals
of DUAL illuminite speakers ONLY. Be sure to observe polarity when connecting.
• Do not ground any illuminite output wires or connect any illuminite 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 signal 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.
