ACCESSORIES

• Self-Tapping Screw ………………………………………………….4
• Hexagon Wrench ………………………………………………1 SET

INSTALLATION

Due to the high power output of the R2-A150M 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 R2-A150M over the screw holes, and secure with four self-tapping screws.

REMOVING THE TOP COVER

To use the top inner panel, remove the top cover.

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” (page 13), 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 ( 9 )” (page 5).

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. Speaker Output Terminals
   Connect the Speaker Output Lead (+) / (–) using the Hexagon hole screw of the Speaker Output Terminals ( 1 ).
   • For details on how to connect, see “Cautions on wire lead connections” (page 6).
   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
   • 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
   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.

2. 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 replaceappropriate gain level setting between the amplifier and head unit.

3. Pre-Out Jacks
   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.

4. 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.

5. Fuse
   25 A × 6
   USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES.
   Failure to do so may result in fire or electric shock.

6. Power Supply Terminal
   Connect the Ground Lead (7 ), Remote Turn-on Lead ( 8), and Battery Lead ( 9) using the Hexagon hole screw of the Power Supply Terminal ( 6).
   • For details on how to connect, see “Cautions on wire lead connections” (page 6).

7. 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” (page 13), 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 on page 7 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. 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: 140 A
   • 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” (page 13), 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 tmake 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” (page 13), 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.

Power Supply Terminal

Speaker Output Terminals

NOTES:

• Be sure to use the Hexagon hole screw attached to the Power Supply Terminal (6) or Speaker Output Terminals (1).
• 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
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 (+) 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 R2-A150M 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 R2-A150M 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 R2-A150M turn-on lead. This switch will then be used to turn on (and off) the R2-A150M.
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.
• To use the top inner panel, remove the top cover. See “REMOVING THE TOP COVER” (page 3).

1. Auto Turn-on Switch
   a) For the “DC” Input setting, connecting the Remote Turn-On Lead is not required due to the “REMOTE SENSING” function of this product.
   b) However, the “REMOTE SENSING” function may not work correctly 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 and switch to the “REM” Input setting.
   • The DC offset auto turn-on circuit was designed to work with ONLY high level signals (i.e., speaker level signals). These high level signals usually come from the amplified output of radios, head units, and amplifiers. Because LO signal input (i.e., low level signals) cannot turn on the amplifier, the REMOTE trigger signal must be supplied and the REM setting needs to be used for LO signal input.*

• For details on turning on the unit with the ACC trigger signal, see the Remote Turn-On Lead ( ) section (page 5). 2. Input Level Switch
  a) If input is via the head unit pre-out line using an RCA extension cable (sold separately), set to “LO”.
  b) If input is via the head unit speaker line using a speaker-RCA conversion cable (sold separately), set to “HI”.

  3. Subsonic Filter Adjustment Knob
     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.

  4. Crossover Fr equency Adjustment Knob(LP FILTER)
     Use this control to adjust the crossover frequency between 50 Hz to 400 Hz.

  5. Bass EQ Adjustment Knob
     Add a 50 Hz bass boost up to +12 dB to tune your bass response.

  6. Input Gain Adjustment Knob
     Set the R2-A150M 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.
