source unit.
Blown amplifier fuse: replace with a new fast-blow fuse (same rating).
Power wires not connected: check battery and ground wiring at the amplifier and
check the battery connections.

common ground.

amplifier; measure coil impedance.

Thermal protection circuits are shutting the amplifier off.
Check the location for adequate ventilation. Consult an authorized Clarion audio
dealer.

Review the instructions for setting the gain. Inspect each speaker cone for signs
of damage, such as a frozen cone, burning smell, etc.

Review the installation precautions and diagram in this manual and check all
wiring connections.

Whining or ticking noise when engine on

The amplifier is picking up alternator or radiated noise.
Turn down input gain.
Move the audio cables away from the power wires.
Check the power and ground connections on the amplifier and install an in-line
noise filter on the source unit's power wire.
Check the alternator and/or voltage regulator. Test for a weak battery or add
