[. . . ] CAUTION: These controls are for tuning your system. This symbol means important instructions. WARNING Failure to heed them can result in serious injury or death. This symbol means important instructions. [. . . ] Using the amplifier as a template, mark the four screw locations. Make sure there are no objects behind the surface that may become damaged during drilling. Position the MRP-F600/MRP-M352 over the screw holes, and secure with four self-tapping screws. NOTE: To securely connect the ground lead, use an already installed screw on the metal part of the vehicle (marked (}), sold separately). Be sure this is a good ground by checking continuity to the battery (­) terminal. As much as possible connect all equipment to the same ground point. Attach the terminal covers (supplied) after connections and confirmation of correct operation. How to attach the terminal covers: Attach the left and right terminal covers using the supplied screws (M3 x 12), as shown in the figure below. 1 Right terminal cover 2 Left terminal cover 3 Screw (M3 x 12) NOTE: Do not lift or carry the unit by the attached terminal covers. Before making connections, be sure to turn the power off to all audio components. Connect the yellow battery lead from the amp directly to the positive (+) terminal of the vehicle's battery. 7 RCA Input Jacks Connect these jacks to the line out leads on your head unit using RCA extension cables (sold separately). Be sure to observe correct channel connections; Left to Left and Right to Right. 8 Speaker Level Input Connector These leads are input leads for use with head units not equipped with preamp outputs. When not using the RCA Line Input connectors, you should connect these wires to the speaker output leads of your head unit. The MRP-F600/MRP-M352 accepts input from high power or standard power head units. NOTE: Use either RCA line level or speaker level inputs. 9 Speaker Input Leads These leads are input leads for use with head units not equipped with preamp outputs. Connect these wires to the speaker output leads of your head unit. The MRP-F600/MRP-M352 accepts input from high power or standard power head units. Cautions on wire lead connections (MRP-F600 only) When using third-party wire cables (power supply wire), use the supplied screws to simplify the connection. Refer to the description below for the proper procedure. [. . . ] The head unit's power antenna lead is activated only when the radio is on (turns off in the tape or CD Mode). The head unit's power antenna lead is logic level output (+) 5V, negative trigger (grounding type), or cannot sustain (+) 12V when connected to other equipment in addition to the vehicle's power antenna. If any of the above conditions exist, the remote turn-on lead of your MRP-F600/MRP-M352 must be connected to a switched power source (ignition) in the vehicle. Be sure to use a 3A fuse as close as possible to this ignition tap. [. . . ]
