Problem
Solution
Ampli
fi
er will not turn
on - Power LED off or
Red
- Using a digital multi-meter, check for 12V at the +12V and
REM Connection relative to the ground connection.
- Fuse at the battery or ampli
fi
er is blown. Inspect and replace
as required.
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 2 Ohms per channel (4 Ohms
bridged mono on the XC1420). 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’s
electrical system. Ensure that during operation, the voltage at
the ampli
fi
er does not drop below 10V. Clarion recommends at
least 8 AWG power wire for both +12V and GND connections.
Distorted Audio
- Input gain is not set properly. Adjust as per instructions.
- Source signal is distorted. Reduce source output level.
- Speaker is damaged. Replace as required.
Less bass than
expected
- One speaker or subwoofer may be wired in reverse polarity.
Switch the + and - leads.
- Crossover may be set too low. Adjust to higher frequency.
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 speakers
connectioned, send the ampli
fi
er to Clarion for repair.
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.
- The speaker wire or a passive crossover network may be
picking up electrical noise. Reroute wiring as required.
