If you can’t find the specified capacity fuse at your store etc., consult your Kenwood dealer.2 Battery terminal (POWER IN BATT.)3 Ground terminal (GND)4 Power control terminal (P.CON)Controls the unit ON/OFF.

NOTEControls the unit power. Be sure to connect it with all the systems.5 SPEAKER OUTPUT terminalsAs this unit accepts speakers with a minimum impedance of 2 ohm, connect speakers with 2- ohm or higher impedance to these terminals.6 BASS BOOST LEVEL controlSets the low frequency level to be compensated.7 LPF FREQUENCY controlThis control adjusts the frequency band output from this unit.8 INPUT SENSITIVITY controlSet this control according to the pre-output level of the center unit connected with this unit.

NOTEFor the pre-output level, refer to the <Specifications> in the instruction manual of the center unit.9 LINE IN terminal0 Power indicatorWhen the power is turned on, the Power indicator lights.

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

PROBLEM POSSIBLE CAUSE SOLUTIONNo 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 ª/·polarity.

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

• The switches may be set improperly.

• Connect them properly checking the ª/·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>.
