SPEAKER TERMINAL 2. BASS BOOST CONTROL By using the BASS BOOST function, bass notes at 45Hz are emphasized as much as 18dB. 3. PHASE SHIFT SWITCH(0 ~ 180 DEGREES) Allows you to change the phase of your subwoofer from 0 to 180 degrees to help compensate for timing differences between mid and sub drivers. 4. VARIABLE LOW-PASS FILTER (50Hz ~ 150Hz) Adjust variable crossover frequency with control as desired. The amplifier input circuit filters out everything above the frequency selected, so only the deepest bass notes are amplified. . 5. VARIABLE SUBSONIC CONTROL(15Hz - 40Hz) 6. INPUT LEVEL(INPUT SENSITIVITY ADJUSTMENT) This control adjust the amplifier's input sensitivity. [. . . ] Then make the connection to the "BATT"connection on the amplifier. If multiple amplifiers are being used, use cables (each with it's own fuse at the battery) or a # O or #2 cable from the fuse holder at the battery to a distribution block at or near the amplifier's location. Connect all line inputs and outputs using high-quality RCA-RCA cables. Insert fuse(s) at the battery fuse holder(s). Recheck all connections before powering up. Set all level controls to their least sensitive positions and set all crossover controls, switches, etc. Once the system is powered up, set the volume control on the head unit to about the 2 O'clock position, and then set all the amplifiers' level controls for maximum output level. Further fine tuning of the various controls may be m\necessary to obtain the desired results. Precautions 1. Before you drill or cut any holes, investigate your car's layout very carefully. Take care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring. . Do not operate the amplifier when it is unmounted. Attach all audio system components securely within the automobile to prevent damage, especially in an accident 3. Do not mount this amplifier so that the wire connections are unprotected or in a pinched condition, or likely to be damaged by nearby objects. Be sure to select a location inside your vehicle which has adequate ventilation. . [. . . ] If the Protection LED still comes on, then the amplifier is faulty. Amplifier(s) gets very hot. Check that the minimum speaker impedance for that model is correct. Check that there is good airflow around the amplifier. In some applications, an external cooling fan many be required. Distorted Sound Check that the Level control(s) is set to match the signal level of the head unit. [. . . ]
