Safety precautions WARNING Take the following precautions to prevent fire and avoid personal injury : *When extending the battery cable, or ground cable, use bmm? (AWNING) or larger automotive grade cable to avoid cable deterioration or damage to the covering. » Check that no metal objects (coins, tools, etc.) arg left inside the unit to avoid short circuits. »if you smell or see smoke, turn the power off immediately and consult your Ken wood dealer.
Installation procedure 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 cables of the units. . Connect the center unit and this unit according to the required application. 5. Connect the speaker cables and sigma servo feed back cables. 6. Connect the power cable, power control cable and grounding cable following this order. Install the unit in the car. .

Sigma servo feed back The sound reproduced through conventional amplifiers is distorted due to the counterproductive force produced in the oscillating system of the speaker. The counter electromotive force is particularly high with the woofer which requires a large drive mass.The sigma servo connection reduces distortion caused by the counter electromotive force by including the circuit up to the speaker terminals in the negative feedback loop.
Troubleshooting Guide What might appear to be a malfunction in your unit may just be the result of slight commiseration or misfiring. Before calling service, first check the following table for possible problems.
