INSTALLATION
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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
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.

High-Level Input
(speaker cables)
Low-Level Input
(RCA)
Speaker Connections
Connect speaker wires
observing polarity. The
minimum impedance load
for the DA304, DA602, DA604
and DA904 is 2 ohms stereo
and 4 ohms bridged. Use of
loads lower than these is not
recommended and may cause
amplifier damage. The DA304,
DA602, DA604 and DA904 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.

Typical Bridged Wiring

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,
DA6001 and DA8001.

INSTALLATION
*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
Master/Slave Mode (cont.)
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
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.
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!
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.
The green LED indicator illuminates during normal
operation (POWER) and the red LED indicator
is visible when the amplifier detects a fault
(PROTECT).
