Dual XPR522 Mobile Power Amplifiers Owner's Manual

Please read entire manual before installation. Due to the technical nature of amplifiers. ii 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 ii 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 lo 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 (BAT+)

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 Tum-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.

XPR522 30 amp ATO x 1

XPR540 25 amp ATO x 2
XPR501 M 30 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.

XPR522 10 awg
XPR5408awg
XPR501 M 8 awg

Amplifier Connections

Speaker Connections
Connect speaker wires observing polarity. The minimum impedance load for the XPR522 or XPR540
is 2 ohms stereo and 4 ohms bridged. Use of loads lower than these is not recommended and may cause amplifier damage. The XPR522 and XPR540 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.
