TALLATION
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
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.
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.

Typical Wire Routing
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.
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
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.
OPERATION
Configuration/Setup
Input level Control| 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.
---|---
Input Mode Switch
(XPA4100)| 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.
Crossover Mode
(XPA2100 & XPA4100)| 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.
Crossover Frequency Control| This control allows precise adjustment of
the crossover frequency.
Bass Boost| This control provides additional boost @ 45Hz when used with
subwoofers. Adjust this control with caution – as improper use can damage
speakers!
LED Indicator| The LED indicator illuminates green during normal
operation (POWER) and red when the amplifier detects a fault (PROTECT).
