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 a high incidence of moisture or dust. Moisture or dust that penetrates this unit may result in product failure.

INSTALLATION

Due to the high power output of the MRX-V60/MRX-F30, considerable heat is produced when the amplifier is in operation. For this reason, the amplifier should be mounted in a location that 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 MRX-V60/MRX-F30 over the screw holes, and secure them with four self-tapping screws.

NOTE: To securely connect the ground lead, use an already installed screw on a metal part of the vehicle (marked (★)) or a clean, bare metal spot on the vehicle’s chassis. Be sure this is a good ground by checking the continuity to the battery (–) terminal. Connect all equipment to the same ground point while keeping the wire length as short as possible. These procedures will help eliminate noise.

    • NOTE: The Remote Bass Control function is available only for the mono channel (Subwoofer).

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.
• If the length of the power and ground cables exceeds 1m, or if you connect more than one amplifier, a distribution block should be used. See below for wire gauge recommendations for distribution block connection to battery and ground (depends upon the wire length necessary):
  • MRX-V60 …………………………. 2AWG (33mm2) or 1/0AWG (53mm2)
  • MRX-F30 …………………………. 4AWG (21mm2) or 2AWG (33mm2)
• Ensure that you install a correctly-rated in-line fuse on the power cable near the battery-positive post.

1. Check the wire size.
   • NOTES: Required Wire Size (Battery Lead, Ground Lead):
   • MRX-V60 ……………………….. 4AWG/21mm2
   • MRX-F30 ……………………….. 8AWG/8mm2
   • If the wire gauge used is unknown, ask your dealer.
2. Remove the insulation from the ends of the wire leads by about 7 – 10mm (9/32” – 3/8”). (Fig. 4)
   • NOTES: If the 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 set screw with the hexagon wrench (included) to secure the lead. (Fig. 5) Before making this connection, use insulated shrink tubing to cover any exposed wire extending beyond the terminal.
   • NOTES:
   • Use only the screws included.
   • 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: (Fig. 6)

Remote Turn-On Lead

• 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 MRX-V60/MRX-F30 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 MRX-V60/MRX-F30 will turn on and stay on as long as the ignition switch is on.

If this is objectionable, an SPST (Single Pole, Single Throw) switch, in addition to the 3A fuse mentioned above, may be installed in-line on the MRX-V60/MRX-F30 turn-on lead. This switch will then be used to turn on (and off) the MRX-V60/ MRX-F30. 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

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

• 19. Input Channel Selector Switch (MRX-V60 only)
  • a) This switch setting is for selecting either 2-channel or 4-channel input mode. When set to “1/2”, the signal will be copied from CH-1/2 and sent to CH-3/4, eliminating the need for y-adapters.
  • b) 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.
• 20. Input Gain Adjustment Control
  • Set the MRX-V60/MRX-F30 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.
• 21. Crossover Frequency Adjustment Knob
  • Use this control to adjust the crossover frequency between 50 Hz to 400 Hz.
• 22. Crossover Mode Selector Switch (HP FILTER) (MRX-V60
  • a) 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.
  • b) Set to the “ON” position when the amplifier is used to drive a speaker system not capable of handling lower frequencies or for increased power handling. The frequencies below the crossover point will be attenuated at 12 dB/octave.
• 23. Input Channel Selector Switch (SUB.W) (MRX-V60 Only)
  • a) When this switch is placed in the “1+3+2+4” position, all the signals are mixed and come out from the SUB.W. This setting provides a signal to the subwoofer channel when only 4 channel input is available.
  • b) Setting this switch to “SUB.W” will send the signal at the inputs of SUB.W(L/R) to SUB.W of the MRX-V60.
• 24. Subsonic Filter (MRX-V60 only)
  • The subsonic filter is for cutting ultra-low frequencies from the input signal before being amplified. 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.
• 25. Crossover Frequency Adjustment Knob (LP FILTER) (MRXV60 Only)
  • Add a 50 Hz bass boost up to +12 dB to tune your bass response.
• 26. Bass EQ Adjustment Knob
  • Add a 50 Hz bass boost up to +12 dB to appease your bass needs.
• 27. Crossover Mode Selector Switch (MRX-F30 only)
  • a) Set to the “OFF” position when the amplifier is used to drive a speaker system capable of handling lower frequencies or when using an external electric crossover.
  • b) Set to the “HP” position when the amplifier is used to drive a tweeter/midrange system. 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.
  • c) Set to the “LP” position when the amplifier is used to drive a subwoofer. The frequencies above the crossover point will be attenuated at 12 dB/octave.
• 28. Power Indicator
  • Lights up when power is on.
  • Is off when the power is off.
