KENWOOD KAC-M5014 COMPACT 4 CHANNEL DIGITAL AMPLIFIER

Safety precautions

To prevent injury or fire1 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 metallic 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 KENWOOD dealer.
  • Do not touch the unit during use because the surface of the unit becomes hot and may cause bums if touched.

CAUTION 
To prevent damage to the machine, take the following precautions. Be sure the unit is connected to a 12 V DC power supply 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.When replacing a fuse, only use a new one with the prescribed rating. Using a fu.se with the wrong rating may cause your unit to malfunction. To prevent a short circuit when replacing a fuse, first disconnect the wiring harness.

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

Cleaning the unit

If the front panel gets dirty, tum 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 0 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.
  • hen 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.be 2 0 or greater for stereo connections or 4 0 or greater for bridged connections. When more than one set of speakers are going to be used, calculate the combined impedance of the speakers and then connect suitable speakers to the amplifier.

Troubleshooting Guide

What might appear to be a malfunction in your unit may just be the result of slight misoperation or mlswiring. Before cal/Ing service, first check the following table for possible problems.

Installation

Dimensions

Installation procedure

Remove the ignition key and disconnect the negative terminal of the battery to prevent short circuits. There are two options

RCA INPUT connection
  • A-1  Connect the battery wire.
  • A-2 Connect the ground wire to chassis ground of vehicle.
  • A-3  Connect the power control wire.
  • A-4  Connect the speakers.
  • A-5 I Connect the RCA cable.
SPEAKER INPUT connection
  • B-1  Connect the battery wire.
  • B-2! Connect the ground wire to chassis ground of vehicle.
  • B-3  Connect the speakers.
  • B-4 Cut off the RCA cable, then connect the correct corresponding speaker output from the FACTORY
INSTALLED HEAD UNIT directly
  • Attach the unit.
  • Connect the negative e terminal of the battery.
  • Remove the Dressing panel.
  • Set the unit according to the intended usage (FILTER, INPUT, OUTPUT).
  • Fix the Dressing panel with screws securely.

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 orposite side such as a gasoline tank, brake pipe, or wiring harness, and be carefu not to cause scratches or other damage.

  • Do not install near the dashboard, rear tray, or air bag safety parts.
  • The installation to the vehicle should securely fasten the unit to a place in which it will not obstruct driving. If the unit comes off due to a shock and hits a person or
    safety part, it may cause injury or an accident.
  • After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally.
  • In order to secure the Water-proof & Dust proof performance (IP67&1P66) of this product, use It with the dressing panel firmly attached. If the dressing panel is not installed properly, dust and water may enter and cause a malfunction.

 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 amplifier can deliver.

CAUTION 
If sound is not output normally, immediately tum 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.
