Figure 6. An APA2103 can be configured for mixed-mode operation.
The table provides component values to create a 6 dB/octave crossover
at specified frequencies. Use components that have a ± 5% tolerance
and capacitors rated at 1 OOV.
NOTE: Choose the same frequency for both high- and low-pass
crossovers. Do not overlap frequencies, as this may cause low
impedances that may damage the amplifier.

INSTALLATION
This section lists mounting and wiring precautions for installing a Clarion
APA2103 2-cha nnel car a udio 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
s kill s, do not install the amplifier yourself. Instead, see your a uthorized
Clarion dealer for installation recommendation s.
Mounting Precautions
A lthough the Clarion APA2103 2-channel car audio amplifier incorporates
electronic protection circuits , mounting any amplifier in a confined space
without any air movement can still damage internal circuits over tim e.
Choose a site that provides adequate ventilation around the amplifier. F.or
easy system set-up, mount the amplifier so the controls and fu se will be '
accessible after installation.
In addition, observe these precautions:
• For the most efficient cooling, mount the amplifier so cool a ir runs
along the length of the heatsink, rather than across it. Remember , a ny
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 n eg ative(- ) lead at the batte ry before making any
power connections.
