The Safety of Your Ears is in Your Hands Get the most out of your equipment by playing it at a safe level—a level that lets the sound come through clearly without annoying blar- ing or distortion and, most importantly, with- out affecting your sensitive hearing. Sound can be deceiving. Over time, your hearing “comfort level” adapts to higher volumes of sound, so what sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts. ESTABLISH A SAFE LEVEL: ! Set your volume control at a low setting. ! Slowly increase the sound until you can hear it comfortably and clearly, without dis- tortion. ! Once you have established a comfortable sound level, set the dial and leave it there. <5707000012760V>3

GUIDELINES: ! Do not turn up the volume so high that you can’t hear what’s around you. ! Use caution or temporarily discontinue use in potentially hazardous situations. ! Do not use headphones while operating a motorized vehicle; the use of headphones may create a traffic hazard and is illegal in many areas. About This Product This product is a mono amplifier for subwoofer. If both L (left) and R (right) channels are connected to the RCA input of this product, output is mixed because this product is a mono amplifier. Before connecting/ installing the amplifier WARNING !

Connecting the units! Never wire the speaker negative cable directly to ground. ! Never band together multiple speaker’s nega- tive cables. ! If the system remote control wire of the ampli- fier is connected to the power terminal via the ignition switch (12 V DC), the amplifier will re- main on with the ignition whether the car stereo is on or off, which may exhaust battery if the engine is at rest or idling. ! Install and route the separately sold battery wire as far as possible from the speaker wires. Install and route the separately sold battery wire, ground wire, speaker wires and the am- plifier as far away as possible from the anten- na, antenna cable and tuner. Connecting the speakers This amplifier can be connected to two speak- ers in parallel. Connect the speaker leads to suit the mode according to the figure shown below. Precautions for parallel connection ! When wiring two speakers in parallel, make sure that the synthetic impedance is from 1 W to 8 W to prevent the amplifier from catching fire, generating smoke and/or being damaged. ! When connected in parallel with the syn- thetic impedance less than 1 W, as a nor- mal function, this amplifier may automatically be set on mute if outputting high volume sound. Turn down the volume until the mute function is canceled.

If speaker input wires from a headunit are connected to this amplifier, the amplifier will automatically turn on when the headunit is turned on. When the headunit is turned off, the amplifier turns off automatically. This function may not work with some headunits. In such cases, please use a system remote control wire (sold separately). If multiple am- plifiers are to be connected together synchro- nously, connect the head unit and all amplifiers via the system remote control wire. ! Connect the system remote control wire when you wish to only turn on the car stereo, not the amplifier. ! This amplifier automatically selects an input signal mode between the RCA level and the speaker level by detecting an input signal. Solderless terminal connections ! Since the wire will become loose over time, it must be periodically inspected and tigh- tened as necessary. ! Do not solder or bind the ends of the twisted wires. ! Fasten while making sure to not to clamp the insulating sheath of the wire. ! Use the supplied hexagonal wrench to tighten and loosen the terminal screw of the amplifier and use it to securely fasten the wire. Be careful to avoid excessive tigh- tening of this screw, which may damage the wire. Connecting the power terminal WARNING If the battery wire is not securely fixed to the term- inal using the terminal screws, there is a risk of overheating, malfunction and injury, including minor burns. ! Always use the recommended battery and ground wire, which is sold separately. Con- nect the battery wire directly to the car bat- tery positive (+) terminal and the ground wire to the car body. ! Recommended wires size (AWG: American Wire Gauge) is as follows. The battery wire, the ground wire and the optional direct ground wire must be same size. !

If any parts other than those supplied are used, they may damage internal parts of the amplifier, or be- come loose causing the amplifier to shut down. ! Do not install in: — Places where it could injure the driver or passengers if the vehicle stops suddenly. — Places where it may interfere with the dri- ver, such as on the floor in front of the dri- ver’s seat. ! Install tapping screws in such a way that the screw tip does not touch any wire. This is im- portant to prevent wires from being cut by vi- bration of the car, which can result in fire. ! Make sure that wires do not get caught in the sliding mechanism of the seats or touch the legs of a person in the vehicle as short-circuit may result. ! When drilling to install the amplifier, always confirm no parts are behind the panel and protect all cables and important equipment (e.g. fuel/brake lines, wiring) from damage. CAUTION ! To ensure proper heat dissipation of the ampli- fier, ensure the following during installation: — Allow adequate space above the amplifier for proper ventilation. — Do not cover the amplifier with a floor mat or carpet. ! Place all cables away from hot places, such as near the heater outlet. ! The optimal installation location differs de- pending on the car model. Secure the ampli- fier at a sufficiently rigid location. ! Check all connections and systems before final installation. ! After installing the amplifier, confirm that the spare tire, jack and tools can be easily re- moved. <5707000012760V>12
