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.

For optimum performance, use only the wire  
size listed below or larger. Make sure to use  
the same size power and ground wire.  
When replacing fuses, make sure new fuse  
is the correct type and amperage. Using an  
incorrect fuse could damage the amplifier.

Speaker Connections  
Connect speaker wires  
observing polarity.The  
minimum impedance load  
for the DA604D and DA954D  
is 2 ohms stereo and 2  
ohms bridged. Use of loads  
lower than these is not  
recommended and may  
cause amplifier damage.The  
DA604D and DA954D can be  
wired for stereo,bridged or  
stereo/bridged simultaneous  
operation.

Typical speaker connections shown  
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 6-9foot 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)  
Note: Do not use both low and high level inputs  
at the same time connect only one or the other.

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  
(DA501D and  
DA801D)  
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).
