DUAL DA10004D Mobile Power Amplifiers
Preparation
Please read the 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 the 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 horizontally (recommended) or vertically. 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.
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 the 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 an 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.
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 the 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.

Typical Wire Routing DA6002D
Main Power Connections
The illustrations demonstrate three different wiring options for each unit.
Once the 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 the 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
Amplifier Connections
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.
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 the chassis ground – depending on your particular
installation.
Note: Do not use both low and high-level inputs at the same time – connect only one or the other.
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 the 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
midrange/tweeter combinations and FULL when using 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.
Crossover Control
- This control allows precise adjustment of the crossover frequency.
Bass Boost
- This control provides an additional boost @ 45Hz when used with subwoofers. Adjust this control with caution – as improper use can damage speakers!
Power/Protect Indicators
- Coloured 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).
