INSTALLATION
This section lists Mounting and Wiring Precautions prior to installing the Clarion APX401.4. These safeguards provide enough detail to complete an installation successfully. If you do not have the necessary skills, do not attempt to install the amplifier yourself. Instead, see your authorized Clarion dealer for installation recommendations.
MOUNTING PRECAUTIONS
Although the Clarion APX401.4 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 around the amplifier. For easy system
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 enclo- sures or areas prone to vibration. Do not install the amplifier on plastic or other combustible materials.
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
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 car chassis to minimize resistance and avoid noise problems. Be sure to clean off any paint, prior to making this connection.
5.Add an external fuse on the amplifier’s positive (+) power lead and connect it as close as possible to the vehicle’s (+) battery terminal. Use a fuse rated to the total current consumption of the amplifier(s). Adding an external fuse will protect the electrical system from short circuits that can cause a fire.
