INSTALLATION
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 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.

minimum impedance load
for the DA304, DA602, DA604

loads lower than these is not
recommended and may cause

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.

outputs to the high level input

black wire (signal reference

installation.
Low-Level Input

Note: Do not use both low and high level inputs
at the same time - connect only one or the
other. High level inputs not available on DA4001,

INSTALLATION
Master/Slave Mode
The Dual mono amplifiers feature a Master/Slave mode, where two amplifiers can be
connected together. When two mono amplifiers are connected together, the power
from both amplifiers is combined.

INSTALLATION
Master/Slave Mode (cont.)
*MASTER
For master amplifier, set the switch to master. This will route the signal through Line-out to
the slave amplifier. Set the phase to 0, all adjustments for gain and sound are done on this
amplifier. The remote subwoofer control should be connected to master amplifier as well.
*SLAVE
For slave amplifier, set the switch to slave and phase to 180. Connect the Line-out of master
amplifier to input on this amplifier. All adjustments should be set to minimum.
Connect Data-Link plug from master to slave amplifier. For speaker connection, the positive
(+) of the speaker connects to positive (+) of master and negative (-) of the speaker connects to
positive (+) of slave amplifier. Connect both negatives (-) of master and slave each other.
NOTE: FOR BEST PERFORMANCE, USE WIRE 12 AWG OR THICKER FOR THE NEGATIVE TO
NEGATIVE CONNECTION.
*MINIMUM IMPEDANCE MUST NOT BE LOWER THAN 2 OHMS

INSTALLATION
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.
Crossover Mode
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
FLAT when using with coaxial-type speakers.
Note: Choose FLAT 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!
Subsonic Filter
(DA4001, DA6001 &
DA8001)
Setting this control to the desired frequency will
limit harmful frequencies below the setting from
going to the subwoofer(s), preventing possible
damage from frequencies that subwoofers are not
designed to handle.
LED Indicators
The green LED indicator illuminates during normal
operation (POWER) and the red LED indicator
is visible when the amplifier detects a fault
(PROTECT).
