Problem
Solution
Ampli
fi
er will not turn
on - Power LED off
- Using a digital multi-meter, check for 12V at the +12V
and REM Connections when referenced to the amp ground
connection.
- If the Auto Sensing circuit is being used, try reversing the +
and - connections to the High Level RCA Adapters
Audio stops playing
- Thermal protection circuit has shut down amp to protect
the circuitry. Ensure there is adequate ventilation around the
ampli
fi
er.
- Fuse at the battery or ampli
fi
er is blown. Inspect and replace
as required.
- Ampli
fi
er is loaded below the rated impedance limit. Check
wiring and recon
fi
gure as required.
Amp shuts off at high
volumes
- Ampli
fi
er may not be getting enough power from your vehicle
electrical system. Ensure that during operation, the voltage at
the ampli
fi
er does not drop below 10.6V. Clarion recommends
at least 4 AWG Pure Copper power wire for both +12V and
GND connections.
Distorted Audio
- Input gain is not set properly. Adjust as per instructions.
- Source signal is distorting. Reduce source output level.
- Speaker is damaged. Replace as necessary.
Fuse Blows
- Ampli
fi
er output may be shorted. Check all wiring.
- Ampli
fi
er may be damaged. Remove all speaker wires
and check functionality. If the fuse blows with no speaker
connection, contact the Clarion Service Department.
Whining or ticking
noise
- The ampli
fi
er may be picking up electrical noise that is
traveling on the ground shield of the interconnect.
1. Check for solid ground connections at the source unit and
ampli
fi
er.
2. Run a ground wire from the ampli
fi
er to the source unit.
3. Re-route the interconnect cables away from sources
of electrical noise. Ensure you are using good quality
shielded interconnects.
- A speaker wire or a passive crossover network may be
picking up electrical noise. Reroute wiring as needed.
