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" (page 7). 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 (S-A60M/S-A55V 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 (S-A32F/S-A55V 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. Fuse S-A60M/S-A55V 30 A × 2 S-A32F 40 A USE THE CORRECT AMPERE RATING WHEN REPLACING FUSES. Failure to do so may result in fire or electric shock. 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 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: S-A60M/S-A55V 60 amp fuse S-A32F 40 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" (page 19), and then use the wire of the specified size. 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 8 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. 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 19), and then use the wire of the specified size. 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. Pre-Out Jacks (S-A60M 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. 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-EN ALPINE S-A60M/S-A32F/S-A55V 68-35792Z59-A (EN/FR/ES) Cautio When us wire), use connecti proper p make thi 1.
