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. Do not connect this lead to the fuse block.

To prevent external noise from entering the audio system.

•Locate the unit and route the leads at least 10 cm away from the car harness.

•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, dirt 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.

1RCA Input Jacks

Connect these jacks to the line out leads on your head unit using RCA extension cables (sold separately).

2Speaker Output Terminals

The MRV-F900 has one set of speaker outputs. Be sure to observe correct speaker output connections and phasing. Connect the positive output to the positive speaker terminal and the negative to negative.

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.

NOTES:

•Do not connect speaker leads together or to chassis ground.

•Do not connect the speaker output terminals to the battery lead or to the ground lead. Otherwise it may result in malfunction or fire.
