®MS-RA55 Installation InstructionsImportant Safety Information WARNINGFailure to follow these warnings and cautions could result in personal injury,damage to the vessel, or poor product performance.See the Important Safety and Product Information guide in the product box forproduct warnings and other important information.This device must be installed according to these instructions.Disconnect the vessel's power supply before beginning to install this product.Before applying power to this product, make sure it has been correctlygrounded, following the instructions in the guide. CAUTIONAlways wear safety goggles, ear protection, and a dust mask when drilling,cutting, or sanding.NOTICEWhen drilling or cutting, always check what is on the opposite side of thesurface.You must read all installation instructions before beginning the installation. Ifyou experience difficulty during the installation, contact FUSION ProductSupport.What's In the Box• Mounting gasket• Four 6-gauge, self-tapping screws• Power and speaker wiring harness• Two screw coversTools Needed• Phillips screwdriver• Electric drill• Drill bit (size varies based on surface material and screws used)• Rotary cutting tool or jigsaw• Marine sealant (optional)Mounting Considerations• The stereo must be mounted on a flat surface.• The stereo must be mounted in a location that allows open airflow aroundthe rear of the stereo for heat ventilation.• If you are installing the stereo in a location that may be exposed to water, itmust be mounted within 45 degrees of the horizontal plane.• If you are installing the stereo in a location that may be exposed to water,the cable should have a drip loop to allow water to drip down off the cableand avoid damage to the stereo.• If you need to mount the stereo outside a boat, it must be mounted in alocation far above the waterline, where it is not submerged.• If you need to mount the stereo outside a boat, it should be mounted in alocation where it cannot be damaged by docks, pilings, or other pieces ofequipment.• To avoid interference with a magnetic compass, the stereo should beinstalled at least 15 cm (5.9 in.) away from a compass.Mounting the StereoNOTICEBe careful when cutting the hole to mount the stereo. There is only a smallamount of clearance between the case and the mounting holes, and cuttingthe hole too large could compromise the stability of the stereo after it ismounted.Be careful when installing the stereo in an aluminum boat or a boat with aconductive hull, if you require the electrical system to be isolated from the boathull.Before you can mount the stereo in a new location on the mounting surface,you must select a location in accordance with the mounting considerations.1Trim the template and make sure it fits at the mounting location.2Adhere the template to the mounting surface.3Using a drill bit appropriate for the mounting surface, drill a hole inside thecorner of the dashed line on the template to prepare the mounting surfacefor cutting.4Using a rotary-cutting tool, cut the mounting surface along the inside of thedashed line on the template.5Place the stereo in the cutout to test the fit.6If necessary, use a file and sandpaper to refine the size of the cutout.7After the stereo fits correctly in the cutout, ensure the mounting holes onthe stereo line up with the pilot holes on the template.8If the mounting holes on the stereo do not line up, mark the new pilot-holelocations.9Using an appropriately sized drill bit for the mounting surface and screwtype, drill the pilot holes.10 Remove the template from the mounting surface.11 Make the necessary wiring connections (Connections, page 1).12 Place the mounting gasket on the back of the stereo À.13 Place the stereo in the cutout.14 Secure the stereo to the mounting surface using the included screws Á.15 Snap the screw covers in place Â.ConnectionsThe stereo must be connected to power, to speakers, and to media inputsources to function correctly. You should carefully plan the layout of thestereo, speakers, and your input sources before making any connections.November 2016 Printed in Thailand 190-01934-02_01

Wiring Harness Wire and Connector IdentificationWire Function Wire Color/NumberNotesAntenna ÀConnects the stereo to a typical AM/FM antennausing an RF coaxial connector.If you are installing the stereo on a boat with ametal hull, you must use a ground-dependentantenna, and if you are installing the stereo on aboat with a non-metal hull, you must use aground-independent antenna. See theinstallation instructions provided with yourantenna for more information.Auxiliary in leftAuxiliary in rightÁProvides a red and white RCA stereo line inputfor audio sources, such as a CD or MP3 player.Zone 1 line out (left)Zone 1 line out (right)ÂProvides a full-range output to an externalamplifier, and is associated with the volume andtone for zone 1.Power (+) Yellow Connects to the positive terminal of a 12 Vdcpower source capable of supplying 15 A.Ground (-) Black Connects to the negative terminal of a 12 Vdcpower source. This wire should be connectedbefore connecting the yellow wire. Allaccessories connected to the stereo must sharea common ground location.Amplifier on Blue Connects to an optional external amplifier to turnit on when the stereo turns on.Dim Orange Connects to the boat's illumination wire to dimthe stereo screen when the lights are on.The gauge of the illumination wire must besuitable for the fuse supplying the circuit it isconnected to.Speaker zone 1 left(+)WhiteSpeaker zone 1 left(-)White/blackSpeaker zone 1 right(+)GraySpeaker zone 1 right(-)Gray/blackSpeaker zone 2 left(+)GreenSpeaker zone 2 left(-)Green/blackSpeaker zone 2 right(+)PurpleSpeaker zone 2 right(-)Purple/blackFuse ÃContains the 15 A fuse.Connecting to PowerWhen connecting the stereo to power, you should connect it through theignition or another manual switch.If it is necessary to extend the power and ground wires, use 14 AWG(2.08 mm2) wire. For extensions longer than 1 m (3 ft.), use 12 AWG(3.31 mm2) wire.1Route the power wire À to the ignition or another manual switch Á, androute the black ground wire Â to the battery.2If necessary, route a wire Ã between the switch and the battery .3Route the wiring-harness plug to the stereo.Do not connect the wiring harness to the stereo until after all of the barewire connections have been made.4Connect the black wire to the negative (-) battery terminal.5Connect the power wire to the ignition or another manual switch, andconnect the switch to the positive (+) battery terminal if necessary.6Connect the wiring harness plug to the stereo.Single-Zone System Wiring DiagramÀSpeakersÁWater-tight connectionComplete System WiringItem DescriptionÀZone 2 speakersÁWater-tight connectionÂZone 1 speakersÃAmplifier-on signal wire2 FUSION® MS-RA55 Installation Instructions
