SAFETY PRECAUTIONS
battery in case of a short circuit between the power amplifier and battery. THIS IS A MUST.
The amplifier's built-in fuse will only protect the power amplifierand not the car's battery!
The fuse value is based on the amplifiers rated power and how many amplifiers will be run off
the same power wire. Please see the specification section at the back of this manual for
your amplifiers rated value.
Use high grade wires and connectors.
To ensure maximum power transfer and secure safe connections, it is recommended to use
high grade wires and terminal rings (for connection at battery)
Do not run any wires underneath vehicle.
Exposed wires have a chance of being cut or damaged. It is best to run all wires through the
vehicle under the carpet and/or side panels. This lends to a cleaner installation and less risk of
damage.
Use caution when mounting amplifier.
Remember there are many electrical wires, gas lines, vacuum lines, brake lines as well as a gas
tank in the automobile. Make sure you know where they are when mounting the amplifier to
avoid puncturing lines, shorting wires or drilling holes in the gas tank.
Run signal wires away from electrical wires
To avoid possibility of induced noise from the car's electrical system (i.e. popping noises or
engine noise), run wires away from the car's electrical wiring.
Make all ground wires as short as possible and at the same point.
In order to reduce the chance of ground loops (i.e. engine noise), make the grounding wire as
short as possible to reduce the wire's resistance. Also, when using multiple components, make
sure all units are grounded at the same point.
Avoid sharp edges when running the wires.
To avoid the possibility of power,signal or speaker shorts, be careful not to allowthe
amplifier's wires to come in contact with sharp edges. Use a grommet to protect the wire
when running through the fire wall .
Fuse amplifier's power wire at the battery.
Be sure to fuse the power wire within 12" of the car's battery. This will protect the car's

Built-in Crossover
The Baja amplifiers includea built-in variable **highand low pass crossovers. The
crossover features a variable frequency selection of (80 Hz ~ 1.2k Hz) for precise high pass
filter and (50 Hz ~ 250 Hz) for low pass filter.
** HA1000, HA700M and HA1000M models only have a 50 Hz ~ 250 Hz low pass filter.
FEATURES AND BENEFITS
Treble Boost
For added high frequency performance two 4 channel amplifier models, HA740 & HA1040,
are equipped with a variable 0~12 dB treble boost @ 8k Hz on channels 1 & 2.
Subsonic Filter
Models HA1000, HA700M and HA1000M are equipped with a variable 20~50 Hz subsonic
Phase Control
Mono subwoofer amplifier models, HA700M and HA1000M are equipped with a continuously
adjustable phase lag control on the subwoofer(s) from 0 to 180 degrees. This control helps
to align the phase shift of a subwoofer for a smooth blending.
Bass Boost
For added low frequency performance the amplifiers are equipped with a variable 0~12 dB
bass boost @ 45Hz.
High Level Input
All Baja amps excluding 4 Channel amplifiers have high level input connector to accept high
(speaker) level signal from a factory radio without pre-amp (RCA) output.
RCA Line Output
This pre-amp signal output can be used to connect signal input to an additional amplifier or
crossover at an ease without using splitters.
which could damage thesubwoofers because they can generate over-displacement of the
subwoofer cone.
filter. This filter avoidsthe reproduction of inaudible low frequencies on the amplifier
Tri-Mode Capable (Excluding HA700M & HA1000M models)
If so desired the amplifier may be run in stereo and mono at the same time. For example, this
feature would allow you to run apair of mids and tweeters in stereo and a subwoofer in mono.

Remote Turn-on
Automatically turns amplifier on when connected to the head unit's remote output. The
amplifier will turn on and off with the head unit to save current consumption. This control also
operates the reset circuit for the amplifier's protection. It must be connected with the head
unit in order to reset protection circuits.
Adjustable Input Sensitivity
Allows you to fine-tune the level matching between your source and the power amplifier.
Power and Speaker Terminals
Heavy gauge power and speaker terminals with protective covers are provided for maximum
power and signal transfer with minimal resistance.
under stereo mode and 4 ohm or greater impedance load under bridged (mono) mode. For
Impedance Stability
For 2 and 4 channel amplifiers, they are stable with a 2 ohm or greater impedance load
mono subwoofer amplifiers ( HA700M & HA1000M), they are stable with a 2 ohm or greater
impedance load.
Fuse(s)
This protects the amplifier against short circuits and excessive current.
DC Offset Protection
This circuit protects the output of the amplifier against DC voltage. If for some reason DC
voltage is detected at the output stage, the amplifier will shut down protecting the speakers
from direct current.
5
Short Circuit Protection
The circuit protects the amplifier from damage due to a short found in the speakers or wiring.
If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down.
To resume normal operation, correct the problem and turn the head unit off, then back on. The
amplifier will reset and play again.
Thermal Protection
To protect the amplifier circuitry against damage caused by prolonged exposure to high
temperatures, a thermal protection circuit is activated if the amplifier reaches excessively
high operating temperature. Once the thermal circuit is activated, the amplifier will shut
down to cool off. The Amplifier will automatically turn back on once it cools down to a safe
operating temperature.
Protection Indicator
This red diagnostic LED on the side panel indicates that the amplifier has gone into protection.
Once on, the amplifier will have no output. To resume normal operation, turn head unit off and
back on again. If the amplifier immediately goes back into protection, check for high
temperature, short circuits or low impedance.

POWER CONNECTIONS
Connect the B+ terminal of the amplifier to the car's battery.
At times, the amplifier will need to draw large levels of current that cannot be provided by any
circuit in the car's fuse box. We recommended using a 4 to 10 gauge power wire (red) for
your connections depending on the amplifier size and length of the wire. Strip one end of the
wire to connect to the terminal on the amplifier marked B+. Loosen screw terminal and connect
bare wire and tighten. Use cautionto make sure no stray wire strands come in contact with
surrounding terminals causing short circuits. Run the wire directly to the positive terminal of
the car's battery. Make sure to use an in-line fuse within 12" of the car's battery to protect
the electrical system and amplifier against short circuits and/or power surges.
IMPORTANT! Before making any connections, disconnect the car's battery until
the installation is completed to avoid possible damage to the electrical system.

+12V
Connect the ground terminal of the amplifier to the car's chassis.
For the ground connection, use a 4-10 gauge wire (black) to connect to the terminal marked
GND and then connect it to the car's chassis. Try to keep the length of the cable as short as
possible, preferably less than 6". Also make sure that the point on the car where the
connection is to be made is free of paint and dirt.
Connect the remote terminal of the amplifier to a switchable +12V source.
This connection allows the amplifier to be turned on and off with the power control of the
radio. If the radio has a REMOTE output wire, connect it to the amplifier's terminal
marked REM (using a 16 gauge wire or heavier). Now when the radio is turned on, the amplifier
will automatically turn on. This connection can also be made to the radio's Power Antenna wire.

MOUNTING LOCATION
Before you start the installation, it will be necessary to find a mounting location for the
amplifier. Find a location in which the amplifier will receive adequate ventilation in order to
dissipate the heat it develops during operation. Two popular mounting locations are in the
trunk or under the seat.
Select the location in which you wish to mount the amplifier. Use caution when mounting
the amplifier. There are many wires, gas lines, vacuum lines, brake lines as wellas a gas tank
in the automobile. Make sure youknow where they are when mountingthe amplifier to avoid
puncturing lines, shorting wiresor drilling holes inthe gas tank. Once you are ready, use a
pencil to mark the mounting holes in the bottom panel. After you have marked the locations of
the holes move amplifier out of the way and drill small starter holes to make the tapping
screws easier to install. Use provided screws to tighten down the amplifier.

FOUR CHANNEL SIGNAL CONNECTIONS
(RADIO WITH FRONT AND REAR OUTPUTS)
FRONT REAR
Connect 2 sets of RCA "Y" adaptors to split
the two RCA's from the radio into 4 outputs
(Not Provided)
FOUR CHANNEL SIGNAL CONNECTIONS
(RADIO WITH ONLY ONE SET OF RCA'S)
Connect the RCA output of the head unit (AM/FM cassette player, CD, or DAT)
to the RCA input terminals of the amplifier.
To make these connections, we recommend high quality RCA cables, which are available at your
local car audio retailer. Run signal wires away from electrical wires to avoid possibility of
induced noise from the car's electrical system (i.e. popping noises or engine noise). Please note
that when making these connections the signal inputs correspond with the speaker outputs.
For example: If you connect the radios front right RCA to "CH 1" .......then speaker output
"CH 1" will operate the front right speaker.
SIGNAL CONNECTIONS
will allow you to connect directly to the speaker output of the radio, without the need
of an external adapter.
