Getting Started

Thank you for purchasing the Dual TBX10A 10" ported enclosure with built-in
amplifier. Although Dual has attempted to ensure the information in this manual
is accurate, please be aware that any part of it is subject to change without notice.

Please read entire manual before installation. Due to the technical nature of
amplifiers, it is highly recommended that your Dual TBX10A is installed by a
professional installer or an authorized dealer.

Before You Start

• Always disconnect the negative battery terminal. Consult a qualified technician
for instructions if you are unsure.

• 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 TBX10A. Suggested locations include
behind a seat or in the trunk.

• For optimum performance, make sure to provide at least 1" of space around all
sides of the amplifier.

• Do not mount the TBX10A under carpets or where airflow is restricted.

• Do not install the TBX10A 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.

PREPARATION

3

The following installation instructions are intended to be used as a basic
guideline. If you feel unsure about installing this speaker system yourself, Dual
recommends acquiring the services of a professional car audio installation
center.

Before installation, please review the following guidelines:

1. Be sure to carefully read and understand the instructions before attempting to
install this product.

2. If additional wiring is required, we recommend running all wires prior to
mounting your enclosure in place.

3. To ensure reliable performance and minimize signal or power loss, use the
highest quality connectors available.

4. Never run speaker wires underneath your vehicle. Running speaker wires
inside the vehicle provides the best protection from exhaust, heat and
environmental elements.

5. Avoid running wires over, near or through sharp-edged surfaces. We suggest
you also use rubber grommets to protect any wires routed through metal,
especially the firewall.

6. When running the speaker cable to the amplifier, avoid running it near sources
of high current (i.e. wiring harnesses, battery cables).

Safety First

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

other switched 12 volt source.

Input Signal 

• The amplifier's input signal connects to the receiver's low level (RCA) or high

level (speaker wire) outputs.

CAUTION

• Never run any wires underneath or outside the vehicle.
