Connect the positive output to the positive speaker terminal and the negative to negative.

About Subwoofer Input/Output Terminals (X-A90M/X-A90V 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.
  • Do not connect the speaker (–) terminal to the vehicle’s chassis.
  • 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 wire gauge used is unknown, ask your dealer.
  •  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.
  • 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.
  •  Be sure to use the Hexagon hole screw attached to the Battery Connector or Speaker Connector.
  •  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 CHECKLIST

Please check your head unit for the conditions listed below:

  • Remote Turn-On Lead
  • The head unit’s power antenna lead is activated only when the radio is on (turns off in the tape or CD Mode).
  • 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 X-A90M/X-A70F/X-A90V 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, theX-A90M/X-A70F/X-A90V 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 X-A90M/X-A70F/X-A90V turn-on lead. This switch will then be used to turn on (and off) the X-A90M/X-A70F/X-A90V. Therefore, the switch should be mounted aso 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. Subsonic Filter (X-A90M/X-A90V only) The subsonic filter for cutting ultra low frequencies from the input signal before being amplified. This is desirable for several reasons
  2. Crossover Frequency Adjustment Knob (LP FILTER) (X-A90M/X-A90V only)
  3. Use this control to adjust the crossover frequency between 50 to 400 Hz. Bass EQ Adjustment Knob (X-A90M/X-A90V only)
  4. Add a 50 Hz bass boost up to +12 dB to tune your bass response.
  5. Input Gain Adjustment Control Set the X-A90M/X-A70F/X-A90V 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.
  6. Crossover Mode Selector Switch (X-A70F only)
    •  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.
    •  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.
    •  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.
  7. Crossover Frequency Adjustment Knob (X-A70F/X-A90V only)
  8. Use this control to adjust the crossover frequency between 50 and 400 Hz.
  9. Input Channel Selector Switch (CHANNEL-3/4) (X-A70F/X-A90V only)
    •  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.
    •  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 (X-A90V only)
    •  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.
    •  Set to the “ON” 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.
    •  When this switch is placed in the “1+2+3+4” position, all the signals are mixed and come out from the subwoofer. This setting provides signal to the subwoofer channel when only 4 channel input is available.
    •  Setting this switch to “SUB” will send the signal at the inputs of SUB to subwoofer of the X-A90V.
