In case of problems when installing your MRV-F302, please contact your authorized ALPINE dealer. CAUTION: These controls are for tuning your system. Please consult your authorized Dealer for adjustment. PRECAUTIONS Perform the installation at a location that is level. Make sure the parking brake is on and the ignition is OFF. Always disconnect the cable from the () negative pole of the battery before connecting or disconnecting the MRV-F302. This will prevent the possibility of short circuits. When replacing a blown fuse make sure to replace it with one of the same value.
Be sure to connect the color coded leads according to the diagram. Incorrect connections may cause the unit to malfunction or damage to the vehicle's electrical system. Be sure to connect the speaker () leads to the speaker () terminal. Never connect left and right channel speaker cables to each other or to the vehicle body. This unit is designed for 12 VDC, negative ground systems. Make sure that your vehicle has this type of electrical system before connecting the power cable. When making connections to the car's electrical system, be aware of the factory installed components (e.g. on-board computer). Do not tap into these leads to provide power for this unit. When connecting the MRV-F302 to the fuse box, make sure the fuse for the intended circuit of the MRV-F302 has the appropriate amperage. Failure to do so may result in damage to the unit and/or the vehicle. When in doubt, consult your ALPINE dealer. The MRV-F302 uses female RCA-type jacks for connection to other units (e.g. amplifier) having RCA connectors. You may need an adaptor to connect other units. If so, please contact your authorized ALPINE dealer for assistance. Due to the high power output of the MRV-F302, it is important that all connections are clean and well secured, or damage could result.

Esto ayudar a eliminar el ruido. Tornillos autorroscantes (M4 x 14) Cable de tierra Chasis Agujeros
Due to the high power output of the MRV-F302, 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. Drill the screw holes. 4. Position the MRV-F302 over the screw holes, and secure with four self-tapping screws.
CONNECTIONS (Fig. 2 Fig. 8)
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. c 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. d Speaker Input Leads These leads are input leads for use with head units not equipped with preamp outputs.

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. Secure the ground lead to a location connected to the cars chassis. Make sure this spot is free from dirt, grease or paint to insure a good connection. 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 , 2 RCA Input Jacks (CH3/4), (CH1/2) 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, Right to Right, Front to Front and Rear to Rear. 3 , 4 RCA Pre-out Jacks (CH1+3), (CH2+4) 5 , 6 Speaker Output Terminals (CH1/2), (CH3/4) The MRV-F302 has two sets of speaker outputs. Be sure to observe correct speaker output connections and phasing. In the stereo mode, connect the right speaker outputs to the right speaker and the left to left. Connect the positive output to the positive speaker terminal and the negative to negative. In the bridged mode, connect the left positive to the positive terminal on the speaker and the right negative to the negative terminal of the speaker. 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 ground. NOTE: Do not connect speaker leads together or to chassis ground. 9 Battery Lead Terminal Remote Turn-on Lead Terminal Ground Lead Terminal Insulation Tube

a Battery Lead (Yellow) (Sold Separately) Be sure to add a 30 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, the wire gauge should be 8 AWG or larger. b 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.
Cautions on wire lead connections In case of using the lead (power supply cord) purchased at the market, use the hexagon screws and the hexagon wrench included as the accessory to make connection easier. Improper handling may cause troubles, so make the connections correctly by referring to the description shown below. A special care will be necessary for the connections using the hexagon screws, so we recommend you to ask the connection for your dealer. 1. Check the wire size. Notes: Recommendable wire size used for the unit is AWG7 AWG18. If the wire size used is unknown, ask to the shop you get the unit, service shop, Alpine Service Center, etc. 2. Remove the insulation cover (insulation material such as vinyl, etc.) of the wire leads by about 7 10mm (9/32" 3/ 8") from the lead end to exposure the conduction leads. (Fig. 3) Notes: If length of the conduction leads with the cover removed is too short, incorrect connection may occur and this may cause operation failure or sound interruption. On the other hand, if the length is too long, an electrical short-circuit may occur. 3. Remove the screw attached on the unit. Insert the lead end into the lead terminal. Tighten the hexagon screw with the hexagon wrench, and the lead will be fixed. (Fig. 4) Before making this connection, dress a short-circuit prevention rubber tube to the leads. Notes: Use only the hexagon screws supplied. For the safety, always connect the battery leads last. To prevent disconnection of the leads or drop of the unit, do not grasp the leads when carrying the unit.

The switch modes shown are for CH1/2. Same explanations apply to mode selection for CH3/4. o , s Input Mode Selector Switch a) Set to the "ST" position (center) when the two channels are used in stereo. The CH-1 (or CH2) input will output at the Speaker Output Ter1 ST 1+2 minal CH-1 (or CH-2). b) Set to the "1" position when the two channels are used for one channel of a stereo bridged system. 1 ST 1+2 c) Set to the "1 + 2" position when the two channels are used for a subwoofer system which uses the right channel and left channel signals summed. q, u Crossover Frequency Adjustment Knob Permits adjustment of the crossover frequency, by rotating the knob to select any frequency between 50 to 200 Hz as the crossover point. r, v Input Gain Adjustment Control Set the MRV-F302 input gain knobs to the minimum (4V) position. Using a loud cassette or preferably a CD as a source, slowly turn up the head unit volume until you just hear the sound distort. At that point, reduce the volume one step so the distortion is no longer audible. Keep head unit output at this level and begin increasing the amplifier gain until the maximum output level you desire is reached. To prevent damage to the speakers or amplifier, the maximum output level should not cause bottoming of the speakers or excessive distortion of the amp. w Input Channel Selector Switch a) Setting this switch to 1/2 will send the signal at the inputs of CH1/2 to CH3/4 of the MRV-F302. 3/4 1+3/2+4 This eliminates the need for "Y-adaptors when using a head unit with a single pair of pre-amp output. b) Set this switch to 3/4 to have the inputs of CH3/ 4 accept independent input signals. An ex3/4 1+3/2+4 ample of this application would be the use of a head unit with dual pre-amp outputs. c) Setting this switch to 1 + 3/ 2 + 4 will sum the CH1 and CH3 input and send it to CH3 while 3/4 1+3/2+4 the CH2 and CH4 inputs are summed and sent to CH4.

p , t Crossover Mode Selector Switch a) Set to the "LP" position when the amplifier is used to drive a subwoofer. The frequencies above the crossover point will be attenuated OFF HP LP at 12 dB/octave. b) Set to the "HP" position when the amplifier is used to drive a tweeter/midrange system. The OFF HP LP 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 OFF HP LP speakers with no high or low frequency attenuation.
Please check your head unit for the conditions listed below: (Fig. 5) a. The head unit does not have a remote turn-on or power antenna lead. b. The head unit's power antenna lead is activated only when the radio is on (turns off in the tape or CD Mode). c. The head unit's power antenna lead is logic level output (+) 5V, negative trigger (grounding type), or cannot sustain (+) 12V when connected to other equipment in addition to the vehicle's power antenna. If any of the above conditions exist, the remote turn-on lead of your MRV-F302 must be connected to a switched power source (ignition) in the vehicle. Be sure to use a 3A fuse as close as possible to this ignition tap. Using this connection method, the MRVF302 will turn on and stay on as long as the ignition switch is on.
If this is objectionable, a SPST (Single Pole, Single Throw) switch, in addition to the 3A fuse mentioned above, may be installed in-line on the MRV-F302 turn-on lead. This switch will then be used to turn on (and off) the MRV-F302. Therefore, the switch should be mounted so that is accessible by the driver. Make sure the switch is turned off when the vehicle is not running. Otherwise, the amplifier will remain on and drain the battery. 1 Remote Turn-On Lead 2 Power Antenna 3 Blue/White Wire 4 To other Alpine components' Remote Turn-On Leads 5 SPST Switch (optional) 6 Fuse (3A) 7 As close as possible to the vehicle's ignition tap 8 Ignition Source
