INSTALLATION

Due to the high power output of the R-A75M/R-A60F 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. Attach the Mounting Brackets to the bottom of the amplifier with eight screws.
   
2. Using the amplifier as a template, mark the four screw locations.
3. Make sure there are no objects behind the surface that may become damaged during drilling.
4. Drill the screw holes.
5. Position the R-A75M/R-A60F over the screw holes, and secure with four self-tapping screws.
   

ATTACHING THE LOGO PLATE

The Logo Plate is temporarily affixed to the top cover.

1. Peel the Logo Plate along with the backing sheet from the top cover.
2. Peel the backing sheet from the Logo Plate, then attach it to this unit in your desired direction.

CONNECTIONS

Before making connections, be sure to turn the power off to all audio components.

*1 For details on the wires size to be used, refer to the supplied "Cautions on Power Supply Wires Connection" and "Cautions on Power Supply Wires", and then use the wire of the specified size.
*2 Be sure to add an External Fuse (e.g. Fuse Block, Circuit Breaker) with the battery lead as close as possible to the battery's positive (+) terminal. Add an external fuse with the same capacity, or a slightly larger capacity, as the sum total of the fuse capacities of the amplifier.
For details on the fuse capacity of this machine, see "Battery Lead ( )".
*3 Connect all equipment to the same ground point while keeping wire length as short as possible.
*4 To securely connect the ground lead, use an already installed screw.

To prevent external noise from entering the audio system

• Locate the unit and route the leads at least 10 cm (4") away from the vehicle's 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 or grease if necessary) of the vehicle's 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.

1. Power Supply Terminal
   Connect the Battery Lead ( ), Remote Turn-on Lead ( ), and Ground Lead ( ) using the Hexagon hole screw of the Power Supply Terminal ( ).
   • For details on how to connect, see "Cautions on wire lead connections".
2. Fuse

R-A75M		40 A × 2
R-A60F		30 A × 2

USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES.
Failure to do so may result in fire or electric shock.

3. RCA Input Jacks
   Connect these jacks to the line out leads on your head unit using RCA extension cables or Speaker-RCA Conversion cable (sold separately). Be sure to observe correct channel connections; Left to Left and Right to Right.
4. Pre-Out Jacks (R-A75M only)
   These jacks provide a line level output. This is an ideal output for driving a second subwoofer amp. This output is full-range, and is not affected by the crossover.
5. Remote Bass Control (optional)
   Connect the Remote Bass Control Unit RUX-KNOB.2 (sold separately) to adjust the output level remotely. This is not to replace appropriate gain level setting between the amplifier and head unit.
6. Speaker Output Terminals
   Connect the Speaker Output Lead (+) / (–) using the Hexagon hole screw of the Speaker Output Terminals ( ).
   • For details on how to connect, see "Cautions on wire lead connections".

Be sure to observe correct speaker output connections and polarity in relation to the other speakers in the system. Connect the positive output to the positive speaker terminal and the negative to negative.

About Subwoofer Input/Output (R-A75M only)

• The input is stereo but the output is monaural.
• Reversing subwoofer polarity (swapping positive and negative connections to the subwoofer) may be desirable in some installations for optimum bass performance.

About Bridged Connections (R-A60F only)
In the bridged mode, connect the left positive to the positive terminal of 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.

NOTE:

• Do not connect the speaker (–) terminal to the vehicle's chassis.

7. Battery Lead (sold separately)
   Be sure to add an External Fuse (e.g. Fuse Block, Circuit Breaker) with the battery lead 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. See below for appropriate fuse value requirement:

R-A75M		80 amp fuse
R-A60F		60 amp fuse

• For details on the wires size to be used, refer to the supplied "Cautions on Power Supply Wires Connection" and "Cautions on Power Supply Wires", and then use the wire of the specified size.

8. Remote Turn-On Lead (sold separately)
   Connect this lead to the remote turn-on (positive trigger, (+) 12 V only) lead of your head unit. If a remote turn-on lead is not available, see "CONNECTION CHECK LIST" section for alternative method.
   • When connecting the speaker output leads of the head unit to this unit with a Speaker-RCA Conversion cable (sold separately), you do not need to connect the remote turn-on lead, owing to the "REMOTE SENSING" function of this unit. However, the "REMOTE SENSING" function may not work depending on the signal source connected. In such a case, connect the remote turn-on lead to an incoming power supply cord (accessory power) in the ACC position.
9. Ground Lead (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 while keeping wire length as short as possible.
   • For details on the wires size to be used, refer to the supplied "Cautions on Power Supply Wires Connection" and "Cautions on Power Supply Wires", and then use the wire of the specified size.

Cautions on wire lead connections

When using third-party wire cables (power supply wire), use the supplied screws to simplify the connection. 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.
   • For details on the wires size to be used, refer to the supplied "Cautions on Power Supply Wires Connection" and "Cautions on Power Supply Wires", and then use the wire of the specified size.
   • If the wire gauge used is unknown, ask your dealer.
2. Remove the insulation from the ends of the wire leads by about 7 – 10 mm (9/32" – 13/32").
   

NOTES:

• If length of the exposed wire is too short, a poor connection may occur causing operation failure or sound interruption.
• On the other hand, if the length is too long, an electrical short-circuit may occur.

3. Tighten the hexagon hole screw with the hexagon wrench (Large or Small) (included) to secure the lead.
   Before making this connection, use insulated shrink tubing to cover any exposed wire extending beyond the terminal.

Speaker Output Terminals

(e.g. R-A60F)

NOTES:

• Be sure to use the Hexagon hole screw attached to the Power Supply Terminal ( ) or Speaker Output Terminals ( ).
• For safety reasons, connect the battery leads last.
• To prevent disconnection of the leads or dropping of the unit, do not use the cabling to carry the unit.

CONNECTION CHECK LIST

Please check your head unit for the conditions listed below:

Remote Turn-On Lead

1. The head unit does not have a remote turn-on or power antenna lead.
2. The head unit's power antenna lead is activated only when the radio is on (turns off in the tape or CD Mode).
3. The head unit's power antenna lead is logic level output (+) 5 V, negative trigger (grounding type), or cannot sustain (+) 12 V 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 R-A75M/R-A60F must be connected to a switched power source (ignition) in the vehicle. Be sure to use a 3 A fuse as close as possible to this ignition tap. Using this connection method, the R-A75M/R-A60F 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 3 A fuse mentioned above, may be installed in-line on the R-A75M/R-A60F turn-on lead. This switch will then be used to turn on (and off) the R-A75M/RA60F. 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.

SWITCH SETTINGS

• Before switching each Selector Switch, turn off the power and insert a small screwdriver, etc., perpendicularly to the Switch.

1. Input Gain Adjustment Control
   Set the R-A75M/R-A60F input gain to the minimum position. Using a dynamic CD as a source, increase the head unit volume until the output distorts. Then, reduce the volume 1 step (or until the output is no longer distorted). Now, increase the amplifier gain until the sound from the speakers becomes distorted. Reduce the gain slightly so the sound is no longer distorted to achieve the optimum gain setting.
2. Crossover Frequency Adjustment Knob (LP FILTER) (R-A75M only)
   Use this control to adjust the crossover frequency between 50 Hz to 400 Hz.
3. Bass EQ Adjustment Knob (R-A75M only)
   Add a 50 Hz bass boost up to +12 dB to tune your bass response.
4. Subsonic Filter (R-A75M only)
   The subsonic filter is for cutting ultra low frequencies from the input signal before being amplified. Frequencies lower than the specified frequency are attenuated at 24 dB/octave.
   This is desirable for several reasons:
   • To protect speakers too small or not capable of reproducing ultra low frequencies.
   • To minimize power wasted from reproducing inaudible sound.
   • To protect subwoofers in vented enclosures from over excursion below the tuning frequency.
5. Speaker Input Level Switch
   Switch according to the Speaker input mode.
   1. When making a speaker input connection with RCA Extension Cables (sold separately), set to "LO".
      
   2. When making a speaker input connection with Speaker-RCA Conversion Cables (sold separately), set to "HI".
      
6. Crossover Mode Selector Switch (CHANNEL-1/2) (R-A60F only)
   1. Set to the "OFF" position when the amplifier will be used for driving full range speakers or when using an external electronic crossover. The full frequency bandwidth will be output to the speakers with no high or low frequency attenuation.
      
   2. Set to the "HP" position when the amplifier is used to drive a tweeter/ midrange system.
      At this setting, Crossover Frequency Adjustment Knob ( ) provides adjustment between 50 Hz to 400 Hz. The frequencies below the crossover point will be attenuated at 12 dB/octave.
      

NOTE:

• In this case the maximum Bass EQ boost level is reduced.

3. Set to the "LP" position when the amplifier is used to drive a subwoofer.
   At this setting, Crossover Frequency Adjustment Knob ( ) provides adjustment between 50 Hz to 400 Hz. The frequencies above the crossover point will be attenuated at 12 dB/octave.
   
4. Set to the "HP-H" position when the amplifier is used to drive a tweeter system.
   At this setting, Crossover Frequency Adjustment Knob ( ) provides adjustment between 400 Hz to 6 kHz. The frequencies below the crossover point will be attenuated at 12 dB/octave.
   

7. Crossover Frequency Adjustment Knob (HP/LP FREQ.) (R-A60F only)
   Use this control to adjust the crossover frequency between 50 Hz to 400 Hz.
8. Crossover Frequency Adjustment Knob (HP-HFREQ.) (R-A60F only)
   Use this control to adjust the crossover frequency between 400 Hz to 6 kHz.
9. Input Channel Selector Switch (CHANNEL-3/4) (R-A60F only)
   1. This switch setting is for selecting either 2-channel or 4-channel input mode. When set to "1/2", signal will be copied from CH-1/2 and sent to CH-3/4, eliminating the need for Y-adapters.
      
   2. Setting this switch to "3/4" will keep both inputs, CH-1/2 and CH-3/4 independent.
      A 4-channel source is required for this mode.
      
10. Crossover Mode Selector Switch (CHANNEL-3/4) (R-A60F only)
    1. Set to the "OFF" position when the amplifier will be used for driving full range speakers or when using an external electronic crossover. The full frequency bandwidth will be output to the speakers with no high or low frequency attenuation.
       
    2. Set to the "HP" position when the amplifier is used to drive a tweeter/ midrange system.
       At this setting, Crossover Frequency Adjustment Knob ( ) provides adjustment between 50 Hz to 400 Hz. The frequencies below the crossover point will be attenuated at 12 dB/octave.
       
    3. Set to the "LP" position when the amplifier is used to drive a subwoofer.
       At this setting, Crossover Frequency Adjustment Knob ( ) provides adjustment between 50 Hz to 400 Hz. The frequencies above the crossover point will be attenuated at 12 dB/octave.
       
    4. Set to "BP" if the amplifier is used to drive a midbass or midrange speaker.
       Frequencies lower than the specified frequency set by Crossover Frequency Adjustment Knob ( ), and higher than the frequency specified set by Crossover Frequency Adjustment Knob ( ), are attenuated at 12 dB/ octave.
       
11. Crossover Frequency Adjustment Knob (HP/ LP/BP-L FREQ.) (R-A60F only)
    Use this control to adjust the crossover frequency between 50 Hz to 400 Hz.

NOTE:

• When the Crossover Mode Selector Switch ( ) is set to [BP], adjust the Crossover Frequency Adjustment Knob ( ) and ( ).

12. Crossover Frequency Adjustment Knob (BP-H FREQ.) (R-A60F only)
    Use this control to adjust the crossover frequency between 400 Hz to 6 kHz.

NOTES:

• When the Crossover Mode Selector Switch ( ) is set to [BP], adjust the Crossover Frequency Adjustment Knob ( ) and ( ).

Failure to make the proper connections may result in fire or product damage.

USE ONLY IN CARS WITH A 12 VOLT NEGATIVE GROUND.
(Check with your dealer if you are not sure.) Failure to do so may result in fire, etc.

BEFORE WIRING, DISCONNECT THE CABLE FROM THE NEGATIVE BATTERY TERMINAL.
Failure to do so may result in electric shock or injury due to electrical shorts.

DO NOT ALLOW CABLES TO BECOME ENTANGLED IN SURROUNDING OBJECTS.
Arrange wiring and cables in compliance with the manual to prevent obstructions when driving. Cables or wiring that obstruct or hang up on places such as the steering wheel, gear lever, brake pedals, etc. can be extremely hazardous.

DO NOT SPLICE INTO ELECTRICAL CABLES.
Never cut away cable insulation to supply power to other equipment. Doing so will exceed the current carrying capacity of the wire and result in fire or electric shock.

DO NOT DAMAGE PIPE OR WIRING WHEN DRILLING HOLES.
When drilling holes in the chassis for installation, take precautions so as not to contact, damage or obstruct pipes, fuel lines, tanks or electrical wiring. Failure to take such precautions may result in fire.

DO NOT USE BOLTS OR NUTS IN THE BRAKE OR STEERING SYSTEMS TO MAKE GROUND CONNECTIONS.
Bolts or nuts used for the brake or steering systems (or any other safety-related system), or tanks should NEVER be used for installations or ground connections. Using such parts could disable control of the vehicle and cause fire etc.

KEEP SMALL OBJECTS SUCH AS BATTERIES OUT OF THE REACH OF CHILDREN.
Swallowing them may result in serious injury. If swallowed, consult a physician immediately.

This symbol means important instructions. Failure to heed them can result in injury or property damages.

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. To ensure safety, always contact the dealer where you purchased this product to have the work done.

USE SPECIFIED ACCESSORY PARTS AND INSTALL THEM SECURELY.
Be sure to use only the specified accessory parts. Use of other than designated parts may damage this unit internally or may not securely install the unit in place. This may cause parts to become loose resulting in hazards or product failure.

ARRANGE THE WIRING SO IT IS NOT CRIMPED OR PINCHED BY A SHARP METAL EDGE.
Route the cables and wiring away from moving parts (like the seat rails) or sharp or pointed edges. This will prevent crimping and damage to the wiring. If wiring passes through a hole in metal, use a rubber grommet to prevent the wire's insulation from being cut by the metal edge of the hole.

DO NOT INSTALL IN LOCATIONS WITH HIGH MOISTURE OR DUST.
Avoid installing the unit in locations with high incidence of moisture or dust. Moisture or dust that penetrates into this unit may result in product failure.

Please record the serial number of your unit in the space provided here and keep it as a permanent record. The serial number plate is located on the rear of the unit
