[. . . ] ⷠ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-F550 has two sets of speaker outputs. Be sure to observe correct speaker output connections and phasing in relation to the other speakers in the system. Do not use the speaker (­) terminals as a common lead between the left and right channels. Do not connect this lead to the vehicle's chassis. Do not connect speaker leads together or to chassis ground. 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 60 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, only use 13mm2 ­ 8mm2 (the wire gauge) for this connection. This is an ideal output for driving a separate subwoofer amp. This output is fullrange, and is not affected by the crossover. 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.
