SAFETY PRECAUTIONS

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

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!

Use high grade wire connectors.

To ensure maximum power transfer and secure safe connections, it is recommended to use

high grade barrier spades (for connection at amplifier) 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

avoidpuncturing 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.

Makeallgroundwires as shortas possibleandatthesamepoint.

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

sureallunits aregroundedatthesamepoint.

Avoid sharp edges when running the wires.

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

running through the fire wall .

FEATURES AND BENEFITS

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.

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 willresetandplay 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 L.E.D. indicates that the amplifier has gone in to 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.

Tri Mode Capable

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 a pair of mid and tweeters in stereo and a sub-woofer mono.

Built-in Crossover

The California amplifiers include a built-in variable high or low pass crossover. The crossover

features a variable frequency selection (40Hz ~ 130Hz) for precise high or low pass filtering.

Bass Boost

For added low frequency performance the two channel amplifiers are equipped with 12dB bass

boost.

Power Fusing

This protects theamplifier againstshortcircuits andexcessivecurrent.

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.

High Level Input

Allowing for integration with “Factory SoundSystems” (Models 100SX, 200SX and400SX).

Stable To 2 Ohm Stereo Mode

Stability to 2 ohm in stereo mode, 4 ohms bridged.

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

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.

Connect 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 an 8 to 10 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 +12V. 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 an 8-10 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 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.

SIGNAL CONNECTIONS

Connect the 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.

If a low level RCA signal source is not available, you may still wire the models 100SX, 200SX,

and 400SX 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 strip

connector located on the end of the amplifier to make this connection. The strip connector

shouldbeconnectedwith thefrontor rear, 2channels ofyour headunit.

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.

SPEAKER CONNECTIONS (BRIDGED)

The California amplifiers are capable of being bridged in a mono configuration. This feature

allows you the flexibility of using the amplifier to drive a ** subwoofer or a center channel. In

this configuration the amplifier sums the right and left channel to deliver one channel (mono)

output.

Please note: in order for the amplifier to sum right and left signal information, both right and

left RCA connections must be made.

**CAUTION! In the bridged mode, the amplifier must see a 4 Ohm load or higher. Any

lower than 4 Ohms will cause the amplifier to overheat and possibly cause permanent

damage to the amplifier!

SPEAKER CONNECTIONS (TRI-MODE)

The amplifier is capable of running in a Mono / Stereo mode. This feature gives the amplifier

the ability to run stereo satellites (midbass & tweeter) simultaneously with a mono subwoofer.

These connections are more complicated because they require the use of passive crossover

networks (Not provided) to divide the frequencies to the speakers. We have included a sample

diagram for 4 Ohm connections. If you wish to use multiple speakers to achieve a lower

impedance and higher power, it is strongly recommended that you seek professional advice

from your Profile retailer before attempting to make these connections.

Please Note:In the Tri-mode configuration, the amplifier’s built-in crossover must be set to

the” OFF” position so the speakers receive fullrange output.

CAUTION! In Tri- mode operation, the amplifier must see a 2 Ohm load or higher for the

stereo satellites and no lower than 4 Ohms for the subwoofer(s). Any lower than the

above mentioned impedance will cause the amplifier to overheat and possibly cause

permanent damage to the amplifier.

SETTING THE CROSSOVER AND BASS BOOST

Select your crossover type and frequency.

(Please note: If you intend to use the amplifier in the Tri-mode configuration, it is necessary

tosetthecrossover controltothe“Flat” setting in order toreceivefullrangeoutput)

The California amplifiers are equipped with a built-in variable crossover network allowing you

to select the crossover type (i.e. Low-Pass or Hi-Pass) and the desired crossover point. For

example if you wish to drive a pair of subwoofers, you can select the “Low Pass” setting on the

amplifier to filter out high frequencies. This will send only low frequencies to your subwoofers

(see example settings below). The crossover point should be determined by the speakers

operating range. Pleaserefer tospeaker manufactures recommendedcrossover point.

Select the crossover type on the

amplifiers side panel.

(Low-pass is selected in this example for subwoofers)

FINE TUNE THE SYSTEM

Fine tune the amplifier's input sensitivity.

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 amplifiers 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

withoutdistortion atabout3/4ofthe volume control.

To determine if the amplifiers 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

engine noise.

Before you can properly address the problem, you must first find the component that is

causing the problem. This will take patience and a process of elimination.
