XPA SERIES 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.
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 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.
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.
• Never run any wires underneath or outside the vehicle.

Fuse Rating
When replacing fuses, make sure new fuse
is the correct type and amperage. Using an
incorrect fuse could damage the amplifier.
XPA2100 25 amp ATO x 1
XPA4100 25 amp ATO x 2
XPA6100 20 amp ATO x 2
Power/Ground Wire Size
For optimum performance, use only the wire
size listed below or larger. Make sure to use
the same size power and ground wire.
XPA2100 10 gauge
XPA4100 8 gauge
XPA6100 8 gauge
Main Power Connections
Connect +12V, GND and REM wires accordingly. A suitable fuse MUST be installed on the
+12V lead within 18" of the battery for protection of the vehicle’s electrical system.

XPA SERIES INSTALLATION
Amplifier Connections
Speaker Connections
Connect speaker wires observing
polarity. The minimum impedance
load for the XPA2100 and XPA4100
is 2 ohms stereo and 4 ohms
bridged. The minimum impedance
load for the XPA6100 is 2 ohms.
Use of loads lower than these is
not recommended and may cause
amplifier damage.The XPA2100
and XPA4100 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.

CAUTION
Do not use both low and high level inputs at the same time - connect only one or the other.

XPA SERIES OPERATION
Configuration/Setup
The input level control (gain) is used to obtain the best
possible match between the head unit audio output and
the amplifier input. Begin by turning the input level control
fully counterclockwise. Next, turn up the head unit volume
control around 3/4 of the way up. Adjust the input level
control clockwise until audible distortion is heard, then
slightly counterclockwise to provide the best match.
Repeat for all input level controls.
Select 2 CH mode if the head unit only has 1 pair of RCA
outputs. Plug the RCA’s from the head unit into channels
1/2 or 3/4. All 4 amplifier inputs will receive a signal.
NOTE: There is no fader function when using 2 CH mode.
Select 4 CH mode if the head unit has 2 pairs of RCA
outputs. Plug the RCA’s from the head unit into channels
1/2 and 3/4.
The crossover is used to filter out frequencies above or
below a certain point. Choose LPF when using the amplifier
with subwoofers, HPF when using with midrange/tweeter
combinations and FULL when using with coaxial-type
speakers.
NOTE Choose FULL when using the amplifier in stereo/
bridged simultaneous mode. In this mode, passive
crossovers are required. Failure to use the correct passive
components may damage the amplifier and/or speakers.
Consult a qualified professional for recommendations.
This control allows precise adjustment of the crossover
frequency.
This control provides additional boost @ 45Hz when used
with subwoofers. Adjust this control with caution - as
improper use can damage speakers!
The LED indicator illuminates green during normal
operation (POWER) and red when the amplifier detects a
fault (PROTECT).
