Be careful not to touch the unit not only when using but after using.• DO NOT disassemble the unit since there are no user serviceable parts inside.INSTALLATION OF THE UNITThe following illustration shows a typical installation. However, you should make adjustmentscorresponding to your specific car.Location of the unitUnder the front seatOnto the trunk floor• Mount this unit on a firm surface, such as in thetrunk or under the front seat.• Since heat is generated in the unit, do not mountit near inflammable objects. In addition, mountit in an area that will not prevent the unit fromdissipating the heat.• Do not mount the unit in the places subject toheat: near a radiator, in a glove compartment orin insulated areas such as under a car mat that willprevent the unit from dissipating heat.• When mounting the unit under the front seat, makesure that adjusting the seat position will not catchany wire of the unit.Install the unitProvided screwφ 4 × 20 mm (13/16 in.)Drilled hole Installation board etc.(thickness : 19 mm ormore)• When mounting this unit, be sure to use theprovided screws.• If any other screws are used, there is a risk ofloosening the unit or damaging the parts under thecar floor.• Before drilling holes in the trunk to install the unit,make sure that there is a sufficient space under thetrunk so that you do not drill holes in the fuel tank,etc.INSTALLATION OF THE SIDE COVERProvided screwΦ 3 × 8 mm (1/8 in.)POWER SUPPLYTo metallic body or chassis*(To an accessory terminal)Fuse*Car batteryIgnition switchJVC car receiver, etc.Remote turn-on line*KS-AX5102KS-AX5104KS-AX5101D* Not SuppliedCautionTo prevent short circuits while making connections, keep the battery’s negative terminal disconnected.• When using a power cord (purchased separately), be sure to place the fuse near the battery asshown.• Connect the lead wire (power cord) through which power is supplied directly to the battery’s “ª”terminal only after all the other connections have been made.The proper lead wire connected to each POWER terminal is as follows.• + B and GND: AWG 8 to AWG 4 (The cross section is about 8 mm2 to 21 mm 2.)• REM: AWG 18 to AWG 8 (The cross section is about 0.8 mm 2 to 8 mm 2.)a When you use JVC car receiver with a remote lead, connect to the REM terminal on this unit.b When you connect a unit without a remote lead, connect to the accessory circuit of the car whichis activated by the ignition switch. In this case, noise may occur when the car receiver is turned onor off. To avoid this noise, do not turn on or off the car receiver itself. You can turn on or off the carreceiver along with the on/off operation of the ignition switch.TERMINAL CONNECTIONSWhen making terminal connections, properly fix each terminal with the provided screw by turning it asillustrated.• Use ring terminals (not provided) for secure connection.Notes• Make sure the screw is fixed in place to prevent disconnections.• Avoid over-tightening as it may cause the damage to the screw or its headslot.SPEAKER SYSTEMSNotes• Be sure not to connect the “·” terminals of the speakers to a common point.• If the same lead is used for both left/right or front/rear speaker wirings, this unit cannot be used.Always use the independent leads for each speaker. In this case, redo the wirings.• Use the speakers with an impedance of 2 Ω to 8 Ω (4 Ω to 8 Ω: when used in Bridge Mode).• Use the speakers which have sufficient capacity to the unit.The proper lead connected to each SPEAKER OUTPUT terminal is as follows.KS-AX5104/KS-AX5102: AWG 18 to AWG 12 (The cross section is about 0.8 mm2 to 3.3 mm2).KS-AX5101D: AWG 18 to AWG 8 (The cross section is about 0.8 mm2 to 8 mm2).SPEAKER CONNECTIONSConnection varies depending on the number of the speakers used in your car. Select the appropriateconnection referring to the following diagrams.Notes• Securely connect all the parts. If the connections are loose, due to contact resistance etc., heat willbreak out and may cause an accident.• Run the connection leads under the car mats to prevent accidental disconnections.Å When your receiver is equipped with line output.ı When your receiver is NOT equipped with line output.KS-AX5104 KS-AX5102KS-AX5101D• Connect each lead of the speaker input connector to a speaker positive lead or negative lead of thereceiver.For Customer Use:Enter below the Model No. and Serial No. which arelocated on the top or bottom of the cabinet.Retain this information for future reference.Model No.Serial No.LVT2338-001A[K]• Attach the side cover using the provided screwsafter connected speaker and power supply cablesand installed the unit.Continued to next pageΦ4 × 20 mm(13/16 in.)Φ3 × 8 mm(1/8 in.)[European Union only]
