[. . . ] OWNER'S MANUAL Please read this manual to maximize your enjoyment of the outstanding performance and feature capabilities of the equipment, then retain the manual for future reference. Please read this OWNER'S MANUAL thoroughly to familiarize yourself with each control and function. We at ALPINE hope that your new MRV-F545/MRV-F345 will give you many years of listening enjoyment. In case of problems when installing your MRV-F545/ MRV-F345, please contact your authorized ALPINE dealer. [. . . ] 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. Be sure to observe correct speaker output connections and phasing. 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. NOTE: Do not connect speaker leads together or to chassis ground. 2 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. This is an ideal output for driving a separate subwoofer amp. This output is full-range, and is not affected by the crossover. 5 Amplifier LINK Connector 6 Battery Lead (Yellow) (Sold Separately) Be sure to add a # 80 amp fuse (or four 20A fuses in parallel) 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 8mm2 or larger. 7 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. 8 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. Cautions on wire lead connections When using third-party wire cables (power supply wire), use the supplied hex screws and the hex wrench (included) to simplify the connection. Refer to the description below for the proper procedure. [. . . ] B) Set to the "HP" position when the amplifier is used to drive a tweeter/midrange system. the frequencies below the crossover point will be attenuated at 12 dB/octave. C) Set to the "OFF" position when the amplifier will be used for driving full-range speakers. The full frequency bandwidth will be output to the speakers with no high or low frequency attenuation.
