What is included in the box
In addition to this manual, the box contains:
 Amplifier  (4) Washers
 High-level speaker input harness  (4) Lock washers
 (4) Self tapping screws  (1) Replacement fuse
Mounting precautions
If you lack the necessary skills, do not install the amplifier yourself. See your authorized
Clarion dealer for installation recommendations.
 This unit is exclusively for vehicles with a negative ground, 12V power supply.
 This unit requires additional mobile audio components for proper operation.
 Choose a location in the vehicle that provides adequate ventilation around the amplifier.
Although any moving air dissipates heat, cool air should run along the length of the fins
rather than across them.
CAUTION
Although Clarion amplifiers include heat sinks and protection
circuits, mounting an amplifier in a tight space without any air
movement will damage the unit’s internal circuitry over time.
