[. . . ] Keep the wire away from the car chassis. Design and specifications are subject to change without notice. Halogenated flame retardants are not used in cabinets. Halogenated flame retardants are not used in printed wiring *1 ClassDTechnology The Class D Technology is a method to convert and amplify music signals with MOSFETs to high speed pulse signals. [. . . ] The input level can be adjusted with this control. Turn it in the clockwise direction when the output level of the car audio unit seems low. Turn this control to boost the frequencies around 40 Hz to a maximum of 10 dB. This unit is designed for negative ground 12 V DC Use speakers with suitable impedance. - 2­8 Do not connect any active speakers (with built-in amplifiers) to the speaker terminals of the unit. Doing so may damage the amplifier and active speakers. Avoid installing the unit in areas subject to: - high temperatures such as from direct sunlight or hot air from the heater - rain or moisture - dust or dirt If your car is parked in direct sunlight and there is a considerable rise in temperature inside the car, allow the unit to cool down before use. When installing the unit horizontally, be sure not to cover the fins with the floor carpet etc. If this unit is placed too close to the car audio unit or antenna, interference may occur. In this case, relocate the amplifier away from the car audio unit or antenna. If no power is being supplied to the car audio unit, check the connections. Then drill the holes approximately 3 mm (1/8 in) in diameter and mount the unit onto the board with the supplied mounting screws. the supplied mounting screws are 15 mm (19/32 in) long. Therefore, make sure that the mounting board is thicker than 15 mm (19/32 in). Now you can enjoy clear bass sound with less distortion. Before making any connections, disconnect the ground Be sure to use speakers with an adequate power rating. If you use small capacity speakers, they may be damaged. Do not connect the terminal of the speaker system to the car chassis, and do not connect the terminal of the right speaker with that of the left speaker. Install the input and output cords away from the power supply wire as running them close together can generate some interference noise. Therefore, it may not Perform to its full potential if used with the speaker cords supplied with the car. If your car is equipped with a computer system for navigation or some other purpose, do not remove the ground wire from the car battery. If you disconnect the wire, the computer memory may be erased. [. . . ] Use the THROUGH OUT terminal when you install more amplifiers. Audio signals pass through the THROUGH OUT pin jacks unaffected by any signal processing. *1 If you have the factory original or some other car audio unit without a remote output for the amplifier, connect the remote input terminal (REMOTE) to the accessory power supply. In High level input connection, car audio unit can also be activated without need for REMOTE connection. [. . . ]
