INTRODUCTION

. Amplifiers provide high-performance sound reinforcement for you mobile audio equipment. It's versatility enables compatibility with optional equalizer, frequency dividing network crossovers, and other audio processors In a customized system.

The Multi-Mode bridging capabilities allow flexibility in hosting several different speaker configurations.

To achieve optimum performance, it is highly recommend that you read this owner's manual before beginning the installation

WARNING

High powered audio systems in a vehicle are capable of generating "Live Concert" high level of sound pressure, Continued exposure to excessively high volume sound levels may cause hearing loss or damage. Also, operation of a motor vehicle while listening to audio equipment at high volume levels may impair your ability to hear external sound such as; horns, warning signals, or emergency vehicles, thus constituting to a potential traffic hazard. For safety reasons we recommends listening at lower volume levels while driving.

The mounting position of your amplifier will have a great effect on its ability to dissipate the heat generated during normal operation. It has an ample heat sink for heat dissipation, and is also designed for a thermal shut-down (for heat protection) Circuit, DO NOT enclose the amplifier in a small box or cover it.

Temperatures in car trunks have been measured as high as 175^ (80 Celsus) in the summer time, since the thermal shut-down point for the amplifier is 185^ (85 Celsus) it is easy to see that it must be mounted for maximum cooling capability. To achieve maximum advantage of convection air flow in a enclosed trunk, mount the amplifier in a vertical position, on a vertical surface.

Floor mounting under the seat is usually satisfactory as long as there is at least 1 inch(2 cm) above the amplifier's fins for ventilation.

a) selected a suitable location that is convenient for mounting, is accessible for wiring and has enough room for air circulation and cooling.
b) Use the amplifier as a template to mark the mounting holes, remove the amplifier and drill 4 holes, use extreme caution, inspect underneath surface before drilling.
c) Secure the amplifier by using screws.

CAUTION:

AS A PRECAUTION: IT IS ADVISABLE TO DISCONNECT THE VEHICLE'S BATTERY BEFORE MAKING CONNECTION TO THE +12 volts SUPPLY WIRING (see owner's manual of car for further in formation : min, 20mm^2 ) ( Thickener for planning for additional amplifiers) wire is recommended both the power and grounds.

Both types are available at most mobile audio dealers or installation shops.

1）GROUND:To Vehicle Chassis
To avoid ignition noise caused by ground loops, it is necessary that the amplifiers be grounded to a clean, bare metal surface of the vehicles chassis.

NOTE:

GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT./1 Meter
2.）+12 Volt(Fused)Constant Power:To Battery[+]
Due to the power requirements of the amplifier, this connection should be made directly to the positive (+) terminal of battery. For safety reasons, install an in-line Fuse holder(not included) as close to the battery positive (+) terminal as possible with a rating: not exceeding value of fuses in Amp.
3. Remote Turn-On Input: To Power antenna output of car stereo
This amplifier is turned ON remotely when the vehicle's stereo is turned ON.

(1) Cinch-INPUT L/R These inputs are for signal cables from the source, Always use high quality RCA type shielded cables
(2) Cinch-Output L/R for more amplifiers
(3) Power LED This GREEN LED will illuminate when the amplifier is turned "ON"
(4) Protection LED The amplifier protection circuitry will disable the amplifier if overloaded, short circuit or extremely high temperature conditions are detected. When the protection mode is in operation, the LED indicator will be illuminated, indicating the amplifier has gone into a self-protection mode
(5) Input Sensitivity Adjustment This control adjusts the amplifier's input sensitivity. Input sensitivity is variable from 200mV to 6 volt. Clockwise increases sensitivity. Counterclockwise decreases sensitivity. This knob is not a volume control for the amplifier. The amplifier can be driven to full power with a wide range of signal levels. A lower signal level will require increased sensitivity for full power. A higher signal level will require decreased sensitivity.

ADJUSTMENT AND TUNING

TURNING ON THE AMPLIFIER

The amplifier automatically turns on a few seconds after you turn your vehicle's ignitions switch to ACC or ON or turn on your auto sound system, depending on how you wired the system. The POWER LED on the side of the amplifier lights when the amplifier is on.

Important: Your Amplifier requires 30 amps or more of power from your vehicle's battery during operation. To protect your battery from discharging, do not operate the amplifier unless your vehicle is running. Note: Your amplifier temporarily shuts down if it gets too hot, then restarts automatically once it cools down.

For the best performance, you must set LEVEL(MIN/MAX) on the side of the amplifier to adjust the level of the audio signals.

1. Use a screwdriver to turn LEVEL(MIN/MAX) fully to MIN
2. Tum the auto sound system's volume control to about two-third of its full range.
3. Adjust LEVEL(MIN/MAX) to a comfortable listening level
   Turn up the auto sound system's volume control until the sound begins to distort. Then immediately turn the volume down to a point just before where the distortion began. Caution: Never up turn the auto sound system's volume control more than needed to adjust the audio level, more than thirds of its maximum volume.
4. 1. Adjust LEVEL(MIN/MAX) until the sound is at the maximum level you want the amplifier two produce.
5. Adjust the auto sound system's volume control to a comfortable listening level.

SYMPTOMS	CHECK POINTS CURE
NO SOUND	Is the POWER LED Illuminated? Check fuses in amplifier. Make sure remote lead is connected check signal leads. Check gain control Check Tuncr/ Dock volume level
	Is the PROTECT LED Illuminated? Check for speaker short or amplifier overheating
AMP NOT SWITCHING ON	No power to the amplifier. Check power wire or connections
	No power to remote wire with receiver on	Check connections to radio
	Check fuse Replace fuse if broken
NO SOUND IN ONE CHANNEL	Check speaker leads Respect for short circuit or an open connection.
	Check Audio leads Reverse Left and Right	RCA inputs to determine if it is occurring before the amp
AMP TURING OFF MEDIUM/HIGH VOLUME	Check speaker load Impedance. Make sure proper speaker load impedance recommendations are observed. (If you use an ohm meter to check speaker resistance, please remember that DC resistance and AC impedance may not be the same)
ON	Temperature shut down Turn radio volume down PROTECTION LAMP
	Speaker wires short. Separate speaker wires and isolate
