Safety Precautions

WARNING

DO NOT OPERATE ANY FUNCTION THAT TAKES YOUR ATTENTION AWAY FROM SAFELY DRIVING YOUR VEHICLE. Any function that requires your prolonged attention should only be performed after coming to a complete stop. Always stop the vehicle in a safe location before performing these functions. Failure to do so may result in an accident.
KEEP THE VOLUME AT A LEVEL WHERE YOU CAN STILL HEAR OUTSIDE NOISES WHILE DRIVING.
Excessive volume levels that obscure sounds such as emergency vehicle sirens or road warning signals (train crossings, etc.) can be dangerous and may result in an accident. LISTENING AT LOUD VOLUME LEVELS IN A CAR MAY ALSO CAUSE HEARING DAMAGE.
DO NOT DISASSEMBLE OR ALTER. Doing so may result in an accident, fire or electric shock.
USE THIS PRODUCT FOR MOBILE 12V APPLICATIONS. Use for other than its designed application may result in fire, electric shock or other injury.
DO NOT BLOCK VENTS OR RADIATOR PANELS. Doing so may cause heat to build up inside and may result in fire.
MAKE THE CORRECT CONNECTIONS. Failure to make the proper connections may result in fire or product damage.
USE ONLY IN VEHICLES WITH A 12 VOLT NEGATIVE GROUND. (Check with your dealer if you are not sure.) Failure to do so may result in fire, etc.
BEFORE WIRING, DISCONNECT THE CABLE FROM THE NEGATIVE BATTERY TERMINAL. Failure to do so may result in electric shock or injury due to electrical shorts.
DO NOT ALLOW CABLES TO BECOME ENTANGLED IN SURROUNDING OBJECTS. Arrange wiring and cables in compliance with the manual to prevent obstructions when driving. Cables or wiring that obstruct or hang up on places such as the steering wheel, gear lever, brake pedals, etc. can be extremely hazardous.
DO NOT SPLICE INTO ELECTRICAL CABLES. Never cut away cable insulation to supply power to other equipment. Doing so will exceed the current carrying capacity of the wire and result in fire or electric shock.
DO NOT DAMAGE PIPE OR WIRING WHEN DRILLING HOLES. When drilling holes in the chassis for installation, take precautions so as not to contact, damage or obstruct pipes, fuel lines, tanks or electrical wiring. Failure to take such precautions may result in fire.
DO NOT USE BOLTS OR NUTS IN THE BRAKE OR STEERING SYSTEMS TO MAKE GROUND CONNECTIONS. Bolts or nuts used for the brake or steering systems (or any other safety-related system), or tanks should NEVER be used for installations or ground connections. Using such parts could disable control of the vehicle and cause fire etc.
KEEP SMALL OBJECTS SUCH AS BOLTS OR SCREWS OUT OF THE REACH OF CHILDREN. Swallowing them may result in serious injury. If swallowed, consult a physician immediately

CAUTION

HALT USE IMMEDIATELY IF A PROBLEM APPEARS. Failure to do so may cause personal injury or damage to the product. Return it to your authorized Alpine dealer or the nearest Alpine Service Center for repairing.
HAVE THE WIRING AND INSTALLATION DONE BY EXPERTS. The wiring and installation of this unit requires special technical skill and experience. To ensure safety, always contact the dealer where you purchased this product to have the work done.
USE SPECIFIED ACCESSORY PARTS AND INSTALL THEM SECURELY. Be sure to use only the specified accessory parts. Use of other than designated parts may damage this unit internally or may not securely install the unit in place. This may cause parts to become loose resulting in hazards or product failure.
ARRANGE THE WIRING SO IT IS NOT CRIMPED OR PINCHED BY A SHARP METAL EDGE. Route the cables and wiring away from moving parts (like the seat rails) or sharp or pointed edges. This will prevent crimping and damage to the wiring. If wiring passes through a hole in metal, use a rubber grommet to prevent the wire’s insulation from being cut by the metal edge of the hole.
DO NOT INSTALL IN LOCATIONS WITH HIGH MOISTURE OR DUST. Avoid installing the unit in locations with high incidence of moisture or dust. Moisture or dust that penetrates into this unit may result in product failure.

Before making connections, be sure to turn the power off to all audio components. Connect the yellow battery lead from the amp directly to the positive (+) terminal of the vehicle’s battery. Do not connect this lead to the fuse block.

CAUTION

Caution on connection terminals/parts
- Keep electrically conductive objects away from the unit’s terminals/parts (power terminals, fuses, speaker output terminals, RCA connectors, etc.). Doing so prevents a possible short circuit and damage to the unit.
- Use appropriate electrical source. The person installing this will choose the appropriate electrical source.

To prevent external noise from entering the audio system.

Locate the unit and route the leads at least 10 cm (3-15/16″) away from the car harness.
Keep the battery power leads as far away from other leads as possible.
Connect the ground lead securely to a bare metal spot (remove any paint or grease if necessary) of the car chassis.
Your Alpine dealer knows best about noise prevention measures so consult your dealer for further information.

Input/Output/Power Connector
Input/Output/Power Wire Harness
Subwoofer Output Leads
Be sure to observe correct subwoofer output connections in the system. Connect the positive output (+) to the positive subwoofer terminal and the negative output (-) to the negative subwoofer terminal.
Note:
- Do not connect subwoofer leads together or to chassis ground.
Input Signal Leads
RCA Input Jacks
Connect these jacks to the line out leads on your head unit, you may or may not require extension cable.
Ground Lead (Black)
Connect this lead securely to a clean, bare metal spot on the vehicle’s chassis. Verify this point to be a true ground by checking for continuity between that point and the negative (-) terminal of the vehicle’s battery. Ground all your audio components to the same point on the chassis to prevent ground loops.

SWITCH SETTINGS (Fig. 2)

$Switch Settings $Fig. 2$$

Gain Setting
Set the KTA-200M input gain to the minimum position. Using a dynamic CD as a source, increase the head unit volume until the output distorts. Then, reduce the volume 1 step (or until the output is no longer distorted).
Now, increase the amplifier gain until the sound from the subwoofer becomes distorted. Reduce the gain slightly so the sound is no longer distorted to achieve the optimum gain setting.
Low Pass Filter Selector Switches
Switch number 1 and 2 are for low pass filter settings. Default setting for low pass filter is off.Control section| Switch number| Function
---|---|---
A| 1 & 2| Filter configuration
B| N/A| Gain control

FILTER ConfigurationA :

Filter off position: Switch 2 and 1 down.
Filter is set for 60Hz low pass; switch 2 down and 1 is up.
Filter is set for 80Hz low pass; switch 2 up and 1 is down.
Filter is set for 120Hz low pass; switch 2 up and 1 is up.

Function	Switch number & position
LPF off	2 down & 1 down
LPF 60Hz	2 down & 1 up
LPF 80Hz	2 up & 1 down
LPF 120Hz	2 up & 1 up

Gain controlB :

This control is for input voltage sensitivity adjustment to allow use with various signal sources with RCA level subwoofer outputs.

Full rated output is obtained with the appropriate settings.
Distortion can be had when the gain control is set incorrectly

ALTERNATIVE AMPLIFIER TURN-ON OPTIONS (Fig. 3)

$Alternative Amplifier Turn-on Options $Fig. 3$$

If your head unit does not have a traditional amplifier turn-on lead, refer to the options below for connection.

Please check your head unit for the conditions listed below: (Fig. 3)

a. The head unit does not have a remote turn-on or power antenna lead.
b. The head unit’s power antenna lead is activated only when the radio is on (turns off in Bluetooth or CD mode).
c. The head unit’s power antenna lead is logic level output (+) 5V, negative trigger (grounding type), or cannot sustain (+) 12V when connected to other equipment in addition to the vehicle’s power antenna. If any of the above conditions exist, the remote turn-on lead of your KTA-200M must be connected to a switched power source (ignition) in the vehicle. Be sure to use a 3A fuse as close as possible to this ignition tap. Using this connection method, the KTA-200M will turn on and stay on as long as the ignition switch is on.

If this is objectionable, a SPST (Single Pole, Single Throw) switch, in addition to the 3A fuse mentioned above, may be installed in-line on the KTA- 200M turn-on lead. This switch will then be used to turn on (and off) the KTA- 200M. Therefore, the switch should be mounted so that is accessible by the driver. Make sure the switch is turned off when the vehicle is not running. Otherwise, the amplifier will remain on and drain the battery.
