Clarion APA4320 User Manual

3 . NOTE
1) Keep in mind that it will become the cause
of battery stage fright if engine is cut and
you use it for a long time.
2) When as follows, a protection circuit
operates. Please use correctly after
removing a cause.
• The leather film of a speaker code was torn
and the code contacted the body.
• The speaker terminal short-circuited.
“ 4 . INSTALLATION
• The main part of amplifier carried out
unusual generation of heat.
• When a large output which the main part of
a speaker damages is performed
continuously. Sound stops in this case.
• When sound does not come out after
removing the above-mentioned cause,
please consult with Clarion dealer.
Electrical Connections
This Clarion Amplifier Designed for On-road Vehicle (DC 12V) Purpose.
This section lists mounting and wiring precautions for installing the Clarion APA4320 car audio
amplifier. Combined with the experience of a professional installer, these safeguards are sufficiently
detailed to successfully complete 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 Precaution
■ Although this Clarion amplifier incorporates a large heat sink and protection circuits, mounting
any amplifier in a confined 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 and fuse will be accessible after installation.
■ When you attach this product, please choose the place distant as much as possible from the
Antenna of vehicles. When it attaches near the antenna of vehicles, a noise may occur.

In Addition, Observe These Precautions:
■ For the most efficient cooling, mount the amplifier so cool air runs along the length of the
heatsink. Remember, any moving air will dissipate heat.
■ Mount the amplifier on a rigid surface. Do not install the amplifier on plastic or other combustible
material.
■ 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 main unit power switch is turned OFF.
■ Disconnect the negative (-) lead at the battery before making any power connections.
■ 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.
■ A secure, clean ground connection is critical to the performance of your Clarion car audio
amplifier. Use the shortest ground wire possible to minimize resistance and avoid noise
problems.
■ Add an external fuse (50A) on the positive (+) power lead and connect it as close as possible to
the vehicle's (+) battery terminal. Adding an external fuse will protect the electrical system from
short-circuits that can cause fire.
■ Refer to Figure — ''Electrical connections" when making electrical connections. Connect the
amplifier's positive (+) power lead via a fuse directly to the positive (+) terminal on the car battery.
Do not connect this wire to the car's fuse panel. Use red-insulated 8-gauge wire for the
amplifier's positive (+) power lead and the same gauge black-insulated wire for the ground.
■ Since the speaker output terminal and power supply terminal of this product are block-type
terminals, the tip of each connection code should make connection after about 1cm strip
processing of the wire. To avoid short circuit, please tightly lock the terminal when doing the
wiring. Also regular inspection is recommended on terminal for loosen connection.
■ When replacing the amplifier's fuse, always use one having the same current rating (50A).
Substituting with a higher-rated fuse can reduce protection and may result in serious damage to
the amplifier.
■ Never ground the speakers to the vehicle chassis or body.
■ Make sure that your vehicle's electrical system (i.e., alternator, battery, etc.) is capable of
handling the additional load.
■ To avoid possible noise problems, run the amplifier's positive (+) power lead along one side of
the vehicle to the battery. Run the remote turn-on wire and RCA audio cable down the center,
and route the speaker wires along the remaining side. If wires must cross, run them
perpendicular to each other.
■ When creating passage holes for the power wire, use grommets to eliminate any sharp edges
created during drilling. This will protect the wire from bring nicked and causing a short-circuit.
■ Extra cable cause signal loss and act as an "antenna" for noise. Use only high-quality RCA
cables that are no longer than necessary to make a direct connection with the main unit or
equalizer.
