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

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 as 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 (no more than 36" or
1 meter). 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 signals 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.
• Keep low level inputs away from any power wires to avoid engine noise.
• Never run any wires underneath or outside the vehicle.

Main Power Connections
The illustrations on pages 6 and 7
demonstrate three different wiring
options for each unit. Once desired
configuration has been selected,
connect the +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.
DA6002D - 25A
DA10004D - 25Ax2
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.
DA6002D - 8 awg
DA10004D - 8 awg

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.
Low-Level Input
(RCA)
Speaker Connections
Connect speaker wires
observing polarity. The
minimum impedance load
for the amplifiers is 2 ohms
stereo and 4 ohms bridged.
Use of loads lower than these
is not recommended and may
cause amplifier damage. The
amplifiers can be wired for
stereo, bridged or stereo/
bridged simultaneous
operation.

INSTALLATION
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.
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!
Colored LED indicators illuminate from the plastic
power terminal. The blue LED illuminates during
normal operation (POWER) and the red LED
indicator is visible when the amplifier detects a
fault (PROTECT).
