On the head unit, turn the volume to about 3/4 full level. c. Slowly turn up the input gain control until you hear a small amount of distortion.
Protection Mode When protection mode triggers, the red LED on the subwoofer turns on and the subwoofer shuts down. One of the following reasons can trigger protection mode: input overload, short circuit and extremely high temperature. When the red LED turns on, take the following measures. • Check the system carefully to determine what has caused the protection mode to trigger. • Reset the subwoofer.
Wiring See the section “Installation precautions” on page 3. For safety, disconnect the negative terminal of the vehicle battery prior to wiring. Use only high quality wires for reliable installation to minimize signal or power loss. Make sure wires are not squeezed or damaged by sharp edges. Use rubber bushings for penetrations. Make sure all the cables are securely connected and bare wires are insulated with electric tape.

Make sure to observe speaker polarity. • Make sure the speaker wires are securely connected and insulated with electric tape. Run the wires under the car mats for wire protection.
Remote connection is used to automatically turn on or off the subwoofer every time the connected head unit is turned on or off. If your head unit does not have the remote output wire, connect the REM terminal on the subwoofer to the ignition switch wire of your vehicle. In this case, make sure your head unit is also turned on or off with the operation of the ignition switch to avoid noise occurrence 3.
Problem Protection/Red LED lights up No sound Solution Turn down volume on your head unit to prevent overdriving. Reset the subwoofer by turning it off and on again. If the protection still lights up, the subwoofer is faulty and needs servicing. Check that audio input connection is correctly and securely made. If using low-level input connection, check the RCA cables are correctly and securely plugged. If using high-level input connection, check connection with the speaker wires of your head unit.
