Safety precautions

WARNING To prevent injury or fi re, take the following precautions:

• Mounting and wiring this product requires skills and experience. For safety’s sake, leave the mounting and wiring work to professionals.
• To prevent a short circuit, never put or leave any metal-lic objects (such as coins or metal tools) inside the unit.
• If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your JVC dealer.
• Do not touch the unit during use because the sur-face of the unit becomes hot and may cause burns if touched.

CAUTION To prevent damage to the machine, take the follow-ing precautions:

• Be sure the unit is connected to a 12 V DC power sup-ply with a negative ground connection.
• Do not open the top or bottom covers of the unit.
• Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing.
• When replacing a fuse, only use a new one with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction.
• To prevent a short circuit when replacing a fuse, fi rst disconnect the wiring harness.

NOTE

• If you experience problems during installation, consult your JVC dealer.
• If the unit does not seem to be working right, consult your JVC dealer.

Cleaning the unit
If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth.

CAUTION
Do not wipe the panel with a hard cloth or a cloth dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the panel and / or cause the indicator letters to peel off .

To prevent battery rise
When the unit is used in the ACC ON position without turning the engine ON, it depletes the battery. Use it after starting the engine.

Protection function
The protection function is activated in the following situations:
This unit is equipped with a protection function for protecting this unit and your speakers from various accidents or problems that can occur.
When the protection function is triggered, the amplifier stops operating.

• When a speaker wire may be short-circuited.
• When a speaker output contacts ground.
• When the unit malfunctions and a DC signal is sent to the speaker output.
• When the internal temperature is high and unit won’t operate.
• When detects a low impedance at the speaker connections.

Wiring

• If a buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery wire.
• Do not allow the wire to directly contact the edge of the iron plate by using Grommets.
• Connect the ground wire to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery‘s negative ⊖ terminal. Do not turn the power on if the ground wire is not connected.
• Be sure to install a protective fuse in the power cord near the battery. The protective fuse should be the same capacity as the unit’s fuse capacity or somewhat larger.
• When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier.

Speaker selection
Using speakers with smaller input ratings than the amplifier’s output power would result in smoke generation or equipment failure.

The impedance of the speakers that are going to be connected should be 2 Ω or greater (for stereo connections), or 4 Ω or greater (for bridged connections). When more than one set of speakers are going to be used, calculate the combined impedance of the speak-ers and then connect suitable speakers to the amplifi er.

Troubleshooting Guide

What might appear to be a malfunction in your unit may just be the result of slight misoperation or miswiring. Before calling service, fi rst check the following table for possible problems.

No sound.

(No sound from one side.)

(Blown fuse.)

| • Input (or output) cables are disconnected.

• Protection circuit may be activated.

• Volume is too high.

• The speaker cord is shorted.

| • Connect the input (or output) cables.

• Check connections by referring to “Protection function”.

• Replace the fuse and use lower volume.

• After check the speaker cord and fixing the cause of the short, replace the fuse.

The output level is too small (or too large).| • The input sensitivity adjusting control is not set to the correct position.| • Adjust the control correctly referring to “Controls”.
The sound quality is bad.

(The sound is distorted.)

| • The speakers wire are connected with wrong ⊕ / ⊖ polarity.

• A speaker wire is pinched by a screw in the car body.

• The switches may be set improperly.

| • Connect them properly checking  the ⊕ / ⊖ of the terminals and wires well.

• Connect the speaker wire again so that it is not pinched by anything.

• Set switches properly by referring to “Controls”.

CAUTION

• Do not install in the below locations;
  (Unstable location, In a location that interferes with driving, In a location that gets wet, In a dusty location, In a place that gets hot, In a place that gets direct sunlight, In a location that gets hit by hot air)

• Do not install the unit under the carpet. Otherwise heat build-up occurs and the unit may be damaged.

• Install this unit in a location which allows heat to easily dissipate. Once installed, do not place any object on top of the unit.

• The surface temperature of the amplifier will become hot during use. Install the amplifier in a place where people, resins, and other substances that are sensitive to heat will not come into contact with it.

• When making a hole under a seat, inside the trunk, or somewhere else in the vehicle, check that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or wiring harness, and be careful not to cause scratches or other damage.

• Do not install near the dashboard, rear tray, or air bag safety parts.

System examples

4-channel system

High-power 2-channel system

2-channel + Subwoofer system

Connection

WARNING: Remove the ignition key and disconnect the negative ⊖ terminal of the battery to prevent short circuits.

In a computer-equipped vehicle, when you remove the ⊖ terminal of the battery, the memory may disappear, or a defect may occur in the electrical system of the vehicle. Consult your dealer for further details.

Type A: RCA INPUT connection

WARNING
Particular attention must be given to making good electrical contact at the amplifier-output and speaker terminals.
Poor or loose connections can cause sparking or burning at the terminals because of the very high power that the amplifi er can deliver.

CAUTION

• If sound is not output normally, immediately turn power off and check connections.
• Be sure to turn the power off before changing the setting of any switch.
• If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating.
• Check that no unconnected wires or connectors are touching the car body. Do not remove caps from unconnected wires or connectors to prevent short circuits.
• Connect the speaker wires to appropriate speaker connectors separately. Sharing the negative wire of the speaker or grounding speaker wires to the metal body of the car can cause this unit to fail.
• After installation, check that the brake lamps, turn signal lamps and windshield wipers work properly.

Controls

This is a 4 channel amplifier including 2 stereo amplifiers in a body. One amplifier is referred to as amplifier A and the other is amplifier B. This unit is compatible with a large variety of systems by combining the switches and functions described in the following.

1. FILTER FREQUENCY control (A.ch / B.ch)
   Sets the cutoff frequency when the “FILTER” switch is set to “HPF” or “LPF”.

2. FILTER switch (A.ch / B.ch)
   This switch allows to apply high-pass or low-pass filtering to the speaker outputs.

   • HPF (High-Pass Filter) position: The filter outputs the band of higher frequencies than the frequency set with the “FILTER FREQUENCY” control.

   • OFF position:
     The entire bandwidth is output without filtering.

   • LPF (Low-Pass Filter) position: The filter outputs the band of lower frequencies than the frequency set with the “FILTER FREQUENCY” control.

3. LINE IN terminal (A.ch / B.ch)

4. INPUT SENSITIVITY control (A.ch / B.ch)
   Set this control according to the pre-output level of the HEAD UNIT connected with this unit.

NOTE: For the pre-output level, refer to the “Specifications” in the instruction manual of the HEAD UNIT.
