User manual BLITZ BZA2290

[. . . ] Input sensitivity is variable from 100Millivolts to 4 volts. This knob is not a volume control signal levels. A lower signal level will require increased sensitivity for full power. [. . . ] Keep this ground wire less than one meter (39") in length. Connect the remote terminal to the remote output of the head unit using 14 gauge wire. Connect an empty fuse holder within 300 mm (12") of the battery and run 8 gauge or larger high quality cable from this fuse to the amplifier location. Make sure there is no fuse in this fuse holder. 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. . [. . . ] Remove speaker leads, and reset the amplifier. 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. [. . . ]
