The Reference sub-woofer amplifiers are single-channel amplifiers. There are two sets of terminals to make it easy to connect multiple woofers. Either set of (+/–) terminals may be used when connecting woofers. To the right are four application diagrams to help plan your sub-woofer system installation. NOTE: For simplicity, Figures 3 and 4 do not show power, remote and input connections.
SETTING THE CROSSOVER(S)
Determine your system plans and set the crossover-mode switch accordingly. If your system design does not include a subwoofer, set the crossover mode to FULL and skip to “Setting Input Sensitivity.”
If your system includes a subwoofer, set the crossover mode to HP (high-pass) for your full-range speakers. Adjust the crossover frequency to limit bass, and provide increased system volume with less distortion.

Circuit diagram
No audio (POWER LED is
off).
CAUSE and SOLUTION: No voltage at BATT+ and/or REM terminals, or bad or no ground connection. Check voltages at amplifier terminals with VOM.
No audio (PROTECT LED glows red).
CAUSE and SOLUTION: DC voltage on amplifier output. Amplifier may need service; see enclosed warranty card for service information.
No audio (PROTECT LED glows red).
CAUSE and SOLUTION: Amplifier is overheated. Make sure amplifier cooling is not blocked at mounting location; verify that speaker-system impedance is within specified limits.
No audio (PROTECT LED glows red).
CAUSE and SOLUTION: Voltage less than 9V on BATT+ connection. Check vehicle charging system.
No audio (PROTECT LED glows red).
CAUSE and SOLUTION: Voltage greater than 16V or less than 8.5V on BATT+ connection. Check vehicle charging system.
PROBLEM: Distorted audio.
CAUSE and SOLUTION: Input sensitivity is not set properly, or amplifier or source unit is defective. Check INPUT LEVEL setting, or check speaker wires for shorts or grounds.
Distorted audio (PROTECT LED glows intermittently).
CAUSE and SOLUTION: Short circuit in speaker or wire. Remove speaker leads one at a time to locate shorted speaker or wire, then repair.
Music lacks “punch.”
CAUSE and SOLUTION: Speakers are not connected properly. Check speaker connections for proper polarity.
