Safety precautions

WARNING
To prevent injury or fire, 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.
  • When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with the range of 5 mm² (AWG 10) or more to prevent wire deterioration and damage to the wire coating.
  • 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 burns 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. 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, 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, 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 power indicator goes off and 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 the unit won’t operate.

Wiring

  • Take the battery wire for this unit directly from the battery. If it’s connected to the vehicle’s wiring harness, it can cause blown fuses, etc.
  • 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 wires.
  • 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.
  • For the power cord and ground, use a vehicle-type (fireproof ) power wring cord. (Use a power wiring cord with the range of 5 mm² (AWG 10) or more.)
  • When more than one power amplifier is going to be used, use a power supply wiring wire and protect the 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, amplifier SUB), or 4 Ω or greater (for bridged connections). When more than one set of speakers is going to be used, calculate the combined impedance of the speakers and then connect suitable speakers to the amplifier.  Example>

Installation

NOTE
After wiring, fix the protective cover securely with screws and washers.

Installation procedure
Since there are a large variety of settings and connections possible according to applications, read the instruction manual well to select the proper setting and connection.

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

WARNINGRemove 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.

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 turn the 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 ratings.
  • 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.
