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

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.

Typical Wire Routing

No more than 36"

(1 meter)

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.

Note: Do not use both low and high level inputs

other. High level inputs not available on DA4001,

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).
