INSTALLATION AND WIRING

IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before beginning the

installation.

Mounting the Amplier

• Wear protective eyewear when using tools.

• Choose a safe mounting location. Check clearances on both sides of the location. Be sure that

screws will not puncture brake or fuel lines or wiring harnesses, and that wire routing will not interfere

with vehicle operation. Use caution when drilling or cutting.

• When making electrical connections, make sure they are secure and properly insulated.

• Do not mount the amplier with the heat sink facing downward, as this interferes with cooling.

• Using the amplier as a template, mark the locations of the holes on the mounting surface.

• Drill pilot holes in the mounting surface.

• Attach the amplier to the mounting surface with sheet metal screws.

Wiring the Amplier

Kappa Perfect ampliers feature wire plugs that allow you to make all connections using optional

mating connectors (sold separately). You can also remove the plugs to make direct wiring

connections.

Power and Ground Connections Using an Optional Mating Connector

• First, prepare the mating connector (sold separately) in the vehicle. Strip a short length of the

jacket from the power, ground, and remote turn-on wires from the vehicle. Crimp the terminals

onto the ends of each wire. Insert each wire into the appropriate pin location in the mating

connector housing (see chart below). Push rmly to secure the wires in the housing, then snap

the back panel of the housing into place.

Power and Ground Connections – Direct Hardwire

• Use wire cutters to remove the connector from the amplier wiring harness. Then, strip a short

length of the jacket from each wire.

• Power: Connect the +12V power wire to the positive terminal of the vehicle’s battery. Make sure

the fuse and fuse holder are within 18" (457mm) of the battery.

INFINITY KAPPA

• Ground: Connect the GND wire to the negative terminal of the vehicle’s battery, or to the

vehicle’s chassis near the battery with a screw. NOTE: If possible, remove any paint from the

chassis for best contact. It’s recommended to use a star washer below the ring connector for a

secure connection.

• Remote: Connect the remote turn-on wire to the “Remote Out” lead of the source unit, if using

low-level signal inputs with an aftermarket stereo. NOTE: If you’re using high-level signal inputs

(your vehicle’s speaker wires), the Kappa Perfect amplier’s 12-volt DC oset feature will turn the

amplier on when it senses audio signal. In this case, you will not have to connect the remote

turn-on wire and can tape or cap it o to prevent the introduction of noise.

Power/Protect indicators

The power light will illuminate in green when the amplier is getting power and playing. The light

will illuminate in red if the amp enters protect mode in the event of conditions such as over/under

voltage, short circuit, amplier output circuit failure, or excessive heat.

Line-level Signal Input

• If your source unit oers preamp outputs, connect to the amplier’s L and R preamp inputs using

RCA patch cables.

Speaker-level Signal Input

Speaker-level Input with Optional Mating Connectors

• If your audio system’s source unit does not have line-level outputs, connect the speaker-level

input wires from the amplier to the front and/or the rear speaker output wires of your source

unit.

• If using the amplier wiring plugs, rst, prepare the mating connector (sold separately) in the

vehicle. Strip a short length of the jacket from the speaker wires coming from the source unit in

the vehicle. Crimp the terminals onto the ends of each wire. Insert each wire into the appropriate

pin location in the mating connector housing (see chart below). Push rmly to secure the wires in

the housing.

Speaker-level Input – Direct Connection

• Use wire cutters to remove the connector from the amplier wiring harness. Then, strip a short

length of the jacket from each wire.

• Splice the speaker-level input wires for the amplier to the speaker wires coming from the

source unit in the vehicle. Use solder, butt connectors, or your preferred splicing method. The

12-volt DC oset feature will turn the amplier on when it senses signal.

INPUT LEVEL SELECTION

If you’re sending signal to the amplier using low-level outputs from your source unit, slide

the input level selector to “LO.” If using high-level outputs from your source unit, slide the

selector to “HI.”

Speaker Output – Direct Connection

• Use wire cutters to remove the connector from the amplier wiring harness. Then, strip a short

length of the jacket from each wire.

• Connect your speakers to the amplier’s speaker output wires, observing proper polarity:

connect each amplier’s positive (+) lead to the appropriate positive (+) speaker terminal,

and negative (-) lead to the appropriate negative (-) speaker terminal. NOTE: Speaker-wire

extensions might be necessary.

• KP5004 4-channel operation: Connect the front left speaker leads (white and white/black) to the

front left speaker’s + and - terminals, and the front right speaker leads (gray and gray/black) to

the front right speaker’s + and - terminals. Next, connect the rear left speaker leads (green and

SETTING THE SOUND

Setting the input level

To match your amplier’s input sensitivity (gain) to your source unit’s output level, we recommend

the following procedure:

• Turn the input level control counterclockwise to MIN (minimum).

• Play a dynamic music track through your source unit. Turn the source unit’s volume control to the

3/4 position.

• Turn the input level control dial clockwise towards MAX until you hear distortion in the music

(it’s no longer clear), then turn it counterclockwise until the music sounds clear again. Your input

sensitivity is now set.

Crossover lters

You can adjust your Kappa Perfect amplier’s lters to suit your listening preferences and speaker

conguration.

The KP5004 lets you select either no lter (OFF) for a full-range signal, or a high-pass lter (HPF)

for your front channels if you’re powering a subwoofer with the rear channels. Slide the switch to

choose your desired crossover point.

For the rear channels, you can select between no lter (OFF); a high-pass lter (HPF) if you’re

powering a subwoofer independently, or a low-pass lter (LPF) if you’re using the rear channels

to power a subwoofer in bridged mode. Slide the REAR – HZ switch to choose your desired

crossover point.

TROUBLESHOOTING

PROBLEM No audio and POWER INDICATOR is o.

CAUSE and

SOLUTION

No voltage at BATT+ and/or REM terminals, or bad or no ground connection. Check

voltages at amplier terminals with VOM.

PROBLEM No audio and PROTECT INDICATOR ashes every 4 seconds.

CAUSE and

SOLUTION

DC voltage on amplier output. Amplier may need service; see enclosed warranty

card for service information.

PROBLEM No audio and PROTECT and POWER INDICATORS ash.

CAUSE and

SOLUTION Voltage less than 9V on BATT+ connection. Check vehicle charging system.

PROBLEM No audio and PROTECT INDICATOR is on.

CAUSE and

SOLUTION

Amplier is overheated. Make sure amplier cooling is not blocked at mounting

location. Verify that speaker-system impedance is within specied limits. Or, there

may be voltage greater than 16V (or less than 8.5V) on BATT+ connection. Check

vehicle charging system.

PROBLEM Amplier fuse keeps blowing.

CAUSE and

SOLUTION

The wiring is connected incorrectly or there is a short circuit. Review installation

precautions and procedures. Check wiring connections.

PROBLEM Distorted audio.

CAUSE and

SOLUTION

Gain is not set properly. Check INPUT LEVEL setting. Check speaker wires for shorts

or grounds. Amplier or source unit may be defective.

PROBLEM Distorted audio and PROTECT INDICATOR ashes.

CAUSE and

SOLUTION

Short circuit in speaker or wire. Remove speaker leads one at a time to locate

shorted speaker or wire, and repair.

PROBLEM Music lacks dynamics or "punch."

CAUSE and

SOLUTION

Speakers are not connected properly. Check speaker connections for proper

polarity.
