[. . . ] input level control use this control to match the outputs of your head unit to the amplifier. Starting with your head unit set at about the 2 o'clock position, increase the amp level control until distortion begins to occur, and reduce slightly from this point. low pass frequency control when the crossover selector switch is in "low pass" mode, this control sets the upper frequency limit for audio program sent to the speakers. high pass frequency control when the crossover selector switch is in "high pass" mode, this control sets the lower frequency limit for audio program sent to the speakers.

Starting with your head unit set at about the 2 o'clock position, increase the amp level controls until distortion begins to occur, and reduce slightly from this point. dual low pass frequency controls when one or both of the crossover selector switches is in "low pass" mode, one can set the upper frequency limit for audio program sent to the speakers. dual high pass frequency controls when the one or both of crossover selector switch is in "high pass" mode, one can set the lower frequency limit for audio program sent to the speakers. dual bass boost level controls this control permits adjustment of the bass level up to an increase of approximately 18 dB in either or both pairs of channels. low level inputs this amp features gold-plated RCA input jacks for high impedance input. Use these with car stereo output which uses RCA-type connector cables. high level inputs if your car stereo lacks RCA-type output jacks, you may connect speaker output leads to these input connectors. power LED this indicator is illuminated when power is applied. protection LED this indicator is illuminated when built-in protection circuitry is activated. Remote Bass Boost Plug in the Remote Bass Boost Control wire in here. power fuse the fuse protects the amplifier and your car's electrical system from short circuit conditions. power terminals use these connectors to deliver power, ground and remote turn-on control to the amplifier. speaker connections these terminals are 14K gold plated to guarantee high conductivity and minimum signal loss. 15 Hz-30 KHz 10K Ohms 100 Ohms 250mV 2. 5V 14. 4V DC Neg.

When determining a suitable location in your vehicle for the amp, please remember that it is a high-power electronic device capable of generating high heat. For this reason, always choose a location in your vehicle which has low vibration, adequate ventilation, a minimum of dust, and no moisture. Be sure to mount the amp in such a manner as to allow reasonable airflow over the cooling fins. Mark the location for the mounting screw holes by positioning the amp where you wish to install it and use a scribe (or one of the mounting screws) inserted in each of the mounting holes to mark the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen. [. . . ] If the noise is a "whine" whose pitch follows the engine speed, confirm that the amplifier and any other signal sources (head unit, etc. ) are properly grounded. If the noise is a "clicking" or "popping" noise whose rate follows the engine speed, this usually means that the vehicle is equipped with resistor spark plugs and wires, or that the ignition is in need of service. Check the rounting of the speaker and input wires to make sure they are not adjacent to wires which interconnect lights and other accessories. If the above steps fail to improve or clear noise interference, the system should be checked by a professional mobile audio installer. precautions Do not operate the amplifier when it is unmounted.
