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 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 reduce performance and damage the unit’s internal circuitry over time.

The DPX1851 does not have a fan. Install it such that air can flow to the bottom of the amplifier.

The DPX11551 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.
