INSTALLATION
This section lists mounting and wiring precautions for installing a Clarion
APA4203 (or APA4162) 4-channel car audio amplifier. 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 APA4203 (or APA4162) 4-channel car audio
amplifier incorporates large heat sinks and protection circuits, mounting it in
a tight space without any air movement can still damage internal circuits
over time. Choose a site that provides adequate ventilation around the
amplifier. For easy system set up, mount the amplifier so the controls on the
front panel will be accessible after installation.
In addition, observe these precautions:
♦ For the most efficient cooling, mount the amplifier so cool air runs
along the length of the heatsink, rather than across it. Remember, any
moving air across the heatsink surface will dissipate heat.
♦ Mount the amplifier on a rigid surface inside the vehicle. Do not install
the amplifier on plastic or other combustible materials.
♦ 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.
♦ Before installation, make sure the source unit power switch is in the
OFF position.
♦ Disconnect the negative (-) lead at the battery before making any
power connections.
