Installation procedure, Wiring | Kenwood KAC-6203 specification

■Installation procedure

Since there are 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.

2.Set the unit according to the intended usage.

3.Connect the input and output wires of the units.

4.Connect the speaker wires.

5.Connect the power wire, power control wire and grounding wire following this order.

6.Install the unit in the car.

7.Connect the negative - terminal of the battery.

2WARNING

To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery’s positive terminal.

2CAUTION

•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, winkers, and wipers work properly.

■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 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.

•For the power cord and ground, use a vehicle type (fireproof ) power wring cord with a current capacity greater than the unit’s fuse capacity. (Use a power wiring cord with a diameter of 5 mm² (AWG 10) or greater.)

•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

•The rated input power of the speakers that are going to be connected should be greater than the maximum output power (in Watts) of the amplifier. Use of speakers having input power ratings that are less than the output power of the amplifier will cause smoke to be emitted as well as damage.

•The impedance of the speakers that are going to be connected should be 2Ω or greater (for stereo connections), or 4Ω 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.
