[. . . ] dO NOT USE BOLTS OR NUTS IN THE BRAKE OR STEERING SYSTEMS TO MAKE GROUND CONNECTIONS. Bolts or nuts used for the brake or steering systems (or any other safety-related system), or tanks should NEVER be used for installations or ground connections. Using such parts could disable control of the vehicle and cause fire etc. Return it to your authorized Alpine dealer or the nearest Alpine Service Center for repairing. [. . . ] ⷠKeep the battery power leads as far away from other leads as possible. ⷠConnect the ground lead securely to a bare metal spot (remove any paint or grease if necessary) of the car chassis. ⷠIf you add an optional noise suppressor, connect it as far away from the unit as possible. Your Alpine dealer carries various noise suppressors, contact them for further information. ⷠYour Alpine dealer knows best about noise prevention measures so consult your dealer for further information. 1 Speaker Output Terminals The MRP-F450/MRP-F250 has two sets of speaker outputs. Do not use the speaker (­) terminals as a common lead between the left and right channels. Use a Y-adaptor (sold separately) for the input when bridging the outputs. 3 Ground Lead (Black) (Sold Separately) Connect this lead securely to a clean, bare metal spot on the vehicle's chassis. Verify this point to be a true ground by checking for continuity between that point and the negative (­) terminal of the vehicle's battery. Ground all your audio components to the same point on the chassis to prevent ground loops. 4 Remote Turn-On Lead (Blue/White) (Sold Separately) Connect this lead to the remote turn-on or power antenna (positive trigger, (+) 12V only) lead of your head unit. 5 Battery Lead (Yellow) (Sold Separately) Be sure to add a #50 amp fuse as close as possible to the battery's positive (+) terminal. This fuse will protect your vehicle's electrical system in case of a short circuit. If you need to extend this lead, the wire gauge should be 8 AWG or larger. 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. (Front to Front and Rear to Rear) 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.
