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.
5. Position the R-A90S over the screw holes, and secure with four self-tapping screws.

CONNECTIONS Before making connections, be sure to turn the power off to all audio components. *1 External Fuse*2 *3, 4 Vehicle’s chassis Vehicle’s battery *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 19), and then use the wire of the specified size. *2 Be sure to add an External Fuse (e.g.
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” (page 6). Fuse 30 A × 3 USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES. Failure to do so may result in fire or electric shock.
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. Speaker Output Terminals 1. Check the wire size.
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.
SWITCH SETTINGS • Before switching each Selector Switch, turn off the power and insert a small screwdriver, etc., perpendicularly to the Switch. (Front Side) (Rear Side) Input Gain Adjustment Control Set the R-A90S 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.
Crossover Frequency Adjustment Knob (HP FREQ.) Use this control to adjust the crossover frequency between 50 Hz to 400 Hz. Crossover Frequency Adjustment Knob (HP-H FREQ.) Use this control to adjust the crossover frequency between 400 Hz to 6 kHz. Input Channel Selector Switch (CHANNEL-3/4) 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.
Crossover Frequency Adjustment Knob (LP FILTER) Use this control to adjust the crossover frequency between 50 Hz to 400 Hz. Remote Bass Control 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. Speaker Input Level Switch Switch according to the Speaker input mode. a) When making a speaker input connection with RCA Extension Cables (sold separately), set to “LO”.
About Power Indicator Power Indicator Lights up when power is on. Is off when power is off. Indication color Blue Red (blinking) Status Amplifier circuit is normal. Operating temperature is high. Red Amplifier circuit is abnormal. An electrical short has occurred, or supply current is too high. Operating temperature is too high. Power supply voltage is too high. Solution Turn down the volume of the head unit (input signal). Decrease the vehicle’s interior temperature to a normal level.
