Introduction Meeting a new challenge to realize the best sound possible for the mobile environment AlpineF#1Status For a quarter of a century, Alpine’s goal has been the best sound in the mobile environment despite its harsh physical and electrical conditions. To overcome these severe listening conditions, Alpine has developed its own unique on-board acoustic technology. This is totally different from that of home audio.
4 Channel Amplifier The MRV-F900 is designed to convey all the passion and impact of exceptional performances. The high fidelity circuitry of this 100W x 4-channel power amplifier, consists of high grade audio components. This combination produces beautiful harmonics, aiming at the ultimate in craftsmanship and following the ideas of microdynamics. ■ High performance MOS-FETs used in power supply unit and final stage Unlike regular transistors, MOS-FETs can operate at extremely high speeds.
WARNING WARNING This symbol means important instructions. Failure to heed them can result in serious injury or death. DO NOT OPERATE ANY FUNCTION THAT TAKES YOUR ATTENTION AWAY FROM SAFELY DRIVING YOUR VEHICLE. Any function that requires your prolonged attention should only be performed after coming to a complete stop. Always stop the vehicle in a safe location before performing these functions. Failure to do so may result in an accident.
CAUTION This symbol means important instructions. Failure to heed them can result in injury or material property damage. HALT USE IMMEDIATELY IF A PROBLEM APPEARS. Failure to do so may cause personal injury or damage to the product. Return it to your authorized Alpine dealer or the nearest Alpine Service Center for repairing. HAVE THE WIRING AND INSTALLATION DONE BY EXPERTS. The wiring and installation of this unit requires special technical skill and experience.
Installation Due to the high power output of the MRV-F900, considerable heat is produced when the amplifier is in operation. For this reason, the amplifier should be mounted in a location which will allow for free circulation of air, such as inside the trunk. For alternate installation locations, please contact your authorized Alpine dealer. 1. Using the amplifier as a template, mark the four screw locations. 2. Make sure there are no objects behind the surface that may become damaged during drilling. 3.
Mounting the End Covers • The product’s appearance can be improved by mounting the end covers on the main unit after installation. • Mount the end covers after installing the main unit. 1 Mounting the brackets 1) Use the included machine screws 6 to mount the three included brackets 5 onto the side opposite the terminal surface. 6 5 5 5 Fig.

Connect the yellow battery lead from the amp directly to the positive (+) terminal of the vehicle's battery.
4 Battery Lead (Sold Separately) Be sure to add a fuse as close as possible to the MRV-F900’s battery terminal. This fuse will protect your vehicle’s electrical system and the MRV-F900 in case of a short circuit. If you need to extend this lead, the wire gauge should be AWG4 or larger. NOTES: • Please make sure not to short the exposed connector to any grounded metal surface when replacing the fuse or making initial connection.
Connections Cautions on wire lead connections • Use Power Supply wire sold at your dealer’s store. • Refer to the description below for the proper procedure. If you are in doubt about how to make this connection, consult your dealer. 1 Check the wire size. 2 Remove the insulation from the ends of the wire leads by about 7 – 10mm (9/32" – 3/8"). (Fig. 7) NOTES: • Wire Size (Battery Lead, Ground Lead): Recommended wire size for this unit is AWG4 or larger.
3 Slide the battery lead into the fuse block. • Slide the battery lead (sold separately) into the fuse block (supplied) as below: 1) Dismantle the fuse box. Turn the cap 1 counterclockwise. 2) Turn the hexagon screw 3 of the fuse terminal 2 with a hexagon wrench (supplied). 3) Remove the rubber ring 4 and the metal ring 10 . (They are not used. They are for protection during transportation.) 4) Slide the battery lead 5 (sold separately) through the cap 1 .
Connection Mounting the Terminal Cover • The product’s appearance can be improved by mounting the terminal cover on the main unit after installation. • Mount the terminal cover after the connections have been made and you have checked that operation is normal. 1 Open the door. 1) Use the included hexagonal wrench to remove the two hexagonal screws q fastening the door p. 2) Open the door p. q p Fig.
3 Fastening the door 1) Close the door p. 2) Mount the door p using the two original hexagonal screws q. * Tighten the screws securely so that they do not come loose due to vibrations while the vehicle is moving. NOTES: • Be sure to fasten the door. Failure to do so may lead to malfunction. • The warranty will be invalidated if the unit is used with the door open. q w Fig.
