Troubleshooting
No Output:
• Ensure all terminal strip connections are secure and tight.
• Check both in-line and built-in fuses. Both the +12V and the Remote terminals
must have +12V referenced to the chassis ground.
• Verify that the audio signal source (car radio, equalizer, etc.) is connected and
supplying an output signal.
• To check if the amp is supplying a signal, unplug the cables from the signal
source (but leave them plugged into the amp). Briey tap the center pin of
each disconnected RCA plug with your nger. This should produce a noise
(feedback) in your speakers.
Only One Channel Works:
• Ensure all terminal strip connections are secure and tight.
• Check the Balance control on the head unit (or other source) to ensure it is set
to the midpoint.
• If using the Low-Level RCA input, reverse the input plugs at the amplier
(i.e., switch the L with the R). If the silent channel switches to the other side,
the problem is either in the head unit/other source or the connecting cables.
Weak Output: Adjust the Input Level Control(s) to better match the input signal.
Noise in the Audio:
• Whine (Engine Speed-Dependent): Ensure that the amplier and any other
signal sources (head unit, etc.) are properly grounded.
• Clicking/Popping (Engine Speed-Dependent): This usually indicates that the
vehicle has resistor spark plugs and wires, or the ignition needs servicing.
• Check Wiring: Ensure that the speaker and input wires are not near wires that
interconnect lights and other accessories.
• If these steps don't resolve the noise interference, consult a professional
mobile audio installer.
