INSTALLATION

This section lists Mounting and Wiring Precautions for installing the Clarion APX400.4M. Combined with the experience of a professional installer, these safeguards provide enough detail to successfully complete an installation. If you do not have the necessary skills, do not install the amplifier yourself.

Instead, see your authorized Clarion dealer for installation recommendations.

MOUNTING PRECAUTIONS

Although the Clarion APX400.4M incorporates heat sinks and protection circuits, mounting the amplifier in a tight space without any air movement can still damage internal circuitry over time. Choose a site that provides adequate ventilation and is isolated from the marine environment. For easy system set- up, mount the amplifier so the front panel controls will be accessible after installation.

In addition, observe the following precautions:

1.For the most efficient cooling, mount the amplifier so cool air runs along the length of the fins rather than across them. Remember, any moving air will dissipate heat.

2.Mount the amplifier on a rigid surface. Avoid mounting to subwoofer enclosures or areas prone to vibration.

3.Prior to drilling, make sure proposed mounting holes will not cut into the fuel tank, fuel lines, brake lines (under chassis), or electrical wiring.

WIRING PRECAUTIONS

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

1.Before installation, make sure the source unit Power switch is in the OFF position.

2.Disconnect the negative (-) lead of the battery before making any power connections.

3.When making connections, be sure that each connection is clean and secure. Insulate final connections with electrical tape or shrink tubing. Failure to do so may damage your equipment.

4.A secure clean ground connection is critical to the performance of your Clarion amplifier. Use the shortest ground wire possible and securely connect to the vessel battery to minimize resistance and avoid noise problems.

5.Add an external fuse on the amplifier’s positive (+) power lead and connect it as close as possible to the vessel’s (+) battery terminal. Use a rating that equals the total current consumption at full output of all amplifiers in the system. Adding an external fuse will protect the electrical system from short circuits that can cause a fire.
