SAFETY PRECAUTIONS
Fuseamplifier'spowerwireatthebattery.
Be sure to fuse the power wire within 12" of the car's battery. This will protect the car's
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 amplifier not the car's battery!
Usehighgradewireconnectors.
To ensure maximum power transfer and secure safe connections, it is recommended to use
high grade connectors where needed.
Donotrunanywiresunderneathvehicle.
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.
Usecautionwhenmountingamplifier.
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
avoidpuncturinglines, shortingwiresordrillingholesinthegastank.
Runsignalwiresawayfromelectricalwires.
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.
Makeallgroundwiresasshortaspossibleandatthesamepoint.
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
sureallunitsaregroundedatthesamepoint.
Avoidsharpedgeswhenrunningthewires.
To avoid the possibility of power, signal or speaker shorts, be careful not to allow the
amplifiers wires to come in contact with sharp edges. Use a grommet to protect the wire when
runningthroughthefirewall.

FEATURES AND BENEFITS
DCOffsetProtection
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.
ShortCircuitProtection
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.
Theamplifierwillresetandplayagain.
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.
ProtectionIndicator
This red diagnostic L.E.D. 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
circuitsorlowimpedance.
Built-inCrossover
The amplifier is equipped with a built-in variable low pass crossovers. The crossover features
a variable frequency selection (40Hz ~ 130Hz) for precise high or low pass filtering.
BassBoost
For added low frequency performance the amplifier is equipped with a variable 12 dB bass
boost.

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.
Gold Plated connections
For positive contact, maximum power and signal transfer with minimal resistance.
AdjustableInputSensitivity
Allows you to fine-tune the level matching between your source and the power amplifier. The
controls have been set at the factory to accept average output of most radios, however, fine
tuning may be necessary to optimize signal to the amplifiers input stage.

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
trunkorundertheseat.
Select the location in which you wish to mount the amplifier. Use caution when mounting
amplifier, there are many 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. 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.

IMPORTANT! Before making any connections, disconnect the car's battery until the
installation is completed to avoid possible damage to the electrical system.
Connecttheamplifiertothecar'sbattery.
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 8 gauge power wire for your
connections depending on the amplifier 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 caution to make sure no stray wire stands 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.
Connect the ground terminal of the amplifier to the car's chassis.
For the ground connection, use a 4-8 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 terminal, connect it to the amplifier's terminal
marked REMOTE (using a 16 gauge wire or heavier). Now when the radio is turned on, the
amplifier will automatically turn on.

HIGH LEVEL CONNECTIONS (OPTIONAL)
If a low level RCA signal source is not available, you may still wire the amplifier with high-level
or speaker level outputs from your head unit. However, only speaker leads from a "floating
ground" system may be used (see diagram below). Use the provided plug to make the following
connections .
Note: The speaker leads from a "common ground" head unit systems should not be connected
to the hi-level input terminals of the following connections.
CAUTION! Before making any connections determine the type of radio to avoid possible
damage to amplifier and/or radio.

Level
Access to the gain sensitivity control for the California
amplifier is located on the side panel. This gain control has
been included to allow adjustment to properly match the
output of the radio. This is one of the most misunderstood
adjustments. By rotating the control in the clockwise
direction, the amplifier's input will become more sensitive and
Min
Max
the music will play louder. This is not a volume control and you will not get more power out of
the amplifier in the maximum position! It may seem to deliver more output, but actually the
system is only playing louder faster as you turn the volume control on the radio. Ideally, to
properly level match the system the goal is to achieve maximum output from the amplifier
withoutdistortionatabout3/4ofthevolumecontrol.
To determine if the amplifier's gain is set properly, turn the system on and slowly increase the
volume control. You should be able to use about 3/4 volume before the system gets loud but
not distorting. It is very important when making these adjustments that you do not over drive
the speakers (at point of distortion) this will cause permanent damage to the speakers. If you
are unable to achieve 3/4 volume before distortion you will need to adjust gain control (in this
case you would reduce the gain). The gain controls should be adjusted very slowly. It may help
to have another person to assist you by adjusting the gain controls while you listen for
distortion.

TROUBLE SHOOTING THE SYSTEM
We have put together this trouble-shooting guide if you experience problems after installing
the amplifier. Please keep in mind that the majority of problems incurred are caused by
improper installation and not the equipment itself. In addition, there are many components in
the system that could cause various signal problems such as inducted electrical noise and
enginenoise.
Before you can properly address the problem, you must first find the component that is
causingtheproblem. Thiswilltakepatienceandaprocessofelimination.
