Problem
Amplifi er will not turn
on - Power LED off
Audio stops playing
Amp shuts off at high
volumes
Distorted Audio
Less bass than
expected
Fuse Blows
Whining or ticking
noise
Solution
- Using a digital multi-meter, check for 12V at the +12V and
REM Connection
- If the Auto Sensing circuit is being used, try reversing the +
and - connections to the High Level RCA Adapters
- Thermal protection circuit has shut down amp to protect
the circuitry. Ensure there is adequate ventilation around the
amplifi er.
- Fuse at the battery or amplifi er is blown. Inspect and replace
as required.
- Amplifi er is loaded below 2 Ohms Stereo or 4 Ohms mono.
Check wiring and reconfi gure as required.
- Amplifi er may not be getting enough power from your vehicle
electrical system. Ensure that during operation, the voltage at
the amplifi er does not drop below 10V. Clarion recommends at
least 4 AWG power wire for both +12V and GND connections.
- Input gain is not set properly. Adjust as per instructions.
- Source signal is distortion. Reduce source output level.
- Speaker is damaged. Replace as necessary.
- One speaker may be wired in reverse polarity. Switch the +
and - leads on one channel.
- Crossover may be set to high. Adjust lower.
- Amplifi er output may be shorted. Check all wiring
- Amplifi er may be damaged. Remove all speaker wires
and check functionality. If the fuse blows with no speakers
connection, send the amplifi er to Clarion for repair.
- The amplifi er may 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
amplifi er.
2. Run a ground wire from the amplifi 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 needed.
