Mount the amplifier on a rigid 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 front panel controls are accessible after installation.

Always use great care when attaching anything to a vehicle! Check clearances on all sides of the planned installation before drilling any holes or installing any screws.

Make sure the holes you drill will not cut into the fuel tank, fuel lines, brake lines (under the chassis) or electrical wiring.

Wiring precautions

Read all wiring precautions. If you are not sure of the connections, contact your authorized Clarion dealer.

• Before you start, make sure the source unit’s power switch is off.

WARNING!

To prevent short circuits during installation, disconnect the vehicle’s negative (-) battery lead before making any power connections.

Extra cable can cause signal loss and act as an antenna for noise. Use only highquality RCA cables that are no longer than necessary to make a direct connection with the source unit and amplifiers.

Make sure each connection is clean and secure. Insulate final connections with electrical tape or shrink tubing.

CAUTION!

Improper connections may damage the equipment.

When routing RCA cables, keep the cables away from the power cables and out put speaker wires.

A good chassis ground connection is critical to minimize resistance and avoid noise problems. Use the shortest wire possible. Clean off any paint prior to making connections. Securely connect the ground wire to the car chassis and the source unit ground.

Add an external fuse to the amp’s positive (+) power lead and connect it as close as possible to the vehicle’s plus (+) battery terminal. Use a fuse rated to the total current consumption of the amplifier. Adding an external fuse protects the electrical system from short circuits that can result in a fire.

Do not open the case. There are no user-serviceable parts inside. If you require assistance, consult your Clarion dealer or an authorized Clarion service center.
