[. . . ] Also, do not touch the amplifier when it is wet. For traffic safety and to maintain safe driving conditions, keep the volume low enough so that you can still hear normal traffic sound. Check the connections of the power supply and speakers if the fuse of the separately sold battery wire or the amplifier fuse blows. Detect the cause and solve the problem, then replace the fuse with another one of the same size and rating. [. . . ] Be sure to protect all cables and important equipment such as fuel lines, brake lines and the electrical wiring from damage. Bass Boost Level Control can boost the level around 60 Hz from 0 to 18 dB. Bass Boost Level Control can be adjusted only when the LPF/HPF select switch is set to a position other than HPF. Use if you want to cut the very low frequency range because it is not necessary for the speakers you are using. To protect the wiring, wrap adhesive tape around it where they lie against metal parts. Do not route wires where they will get hot, for example where the heater will blow over them. If the insulation heats up, it may become damaged, resulting in a short-circuit through the vehicle body. Make sure that wires will not interfere with moving parts of the vehicle, such as the gearshift, handbrake or seat sliding mechanism. Otherwise the protection circuit may fail to work when it should. Never feed power to other equipment by cutting the insulation of the power supply wire to tap from the wire. After making all other connections at the amplifier, connect the battery wire terminal of the amplifier to the positive (+) terminal of the battery. Do not connect both the RCA input and the speaker input at the same time. 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 driver, such as on the floor in front of the driver's seat. Make sure that wires are not caught in the sliding mechanism of the seats, resulting in a short-circuit. Confirm that no parts are behind the panel when drilling a hole for installation of the amplifier. Protect all cables and important equipment such as fuel lines, brake lines and electrical wiring from damage. Install tapping screws in such a way that the screw tip does not touch any wire. This is important to prevent wires from being cut by vibration of the car, which can result in fire. To prevent electric shock, do not install the amplifier in places where it might come in contact with liquids. To ensure proper installation, use the supplied parts in the manner specified. If any parts other than the supplied ones are used, they may damage internal parts of the amplifier, or they may become loose causing the amplifier to shut down. [. . . ] Cut off frequency: 80 Hz Cut off slope: ­12 dB/oct High pass filter . Cut off frequency: 80 Hz Cut off slope: ­12 dB/oct Bass boost . To ensure proper heat dissipation of the amplifier, be sure of the following during installation. --Allow adequate space above the amplifier for proper ventilation. [. . . ]
