5. INSTALLATION AND WIRING
Read these instructions and the following precautions carefully.
What is included in the box
In addition to this manual, the box contains:
• Amplifier
• High-level speaker input harness
Mounting precautions
If you lack the necessary skills, do not install the amplifier yourself. See your autho-
rized 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 reduce performance and damage the unit’s in-
ternal circuitry over time.
The DPX1800 does not have a fan. Install it such that air can
flow to the bottom of the amplifier.
The DPX11500 has two fans. Mounted in the ends of the unit,
they blow through the length of the amplifier. Ensure a 3-inch
clearance between the power/speaker and the control ends for
proper ventilation.
• Mount the amplifier on a firm, flat surface away from subwoofer enclosures or to
any area that is prone to vibration. Do not install the amplifier on plastic or on any
other combustible material.
• For easy system setup, mount the amplifier so that the adjustment controls are
accessible after installation.
