INSTALLATION
The section lists mounting and wiring precautions for installing the Clarion
APA2150G car audio amplifier. Combined with the experience of a professional
installer, these safeguards are sufficiently detailed to successfully complete installa¬
tion. 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 this Clarion amplifier incorporates a large heat sink and protection cir¬
cuits, 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.
In addition, observe these precautions:
• 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 dissi¬
pate 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.
Cautions on installation
1. Be sure to use the screws supplied with this amplifier to install it in your car.
Mounting the machine using screws other than those supplied may lead to mal¬
functioning of the unit.
2. When you mount the machine, be careful not to damage the wiring in your car
with tools or parts such as tapping screws.
Installation procedure
1. Open four holes (o3.5 mm) to mount the unit.
2. Use the four tapping screws (5
x
30) to secure the unit.
3. When mounting the unit on a plastic plate or carpet, use the plate nuts.
Wiring Precautions
• Read all wiring precautions. If you are not sure of the connections, contact your
authorized Clarion dealer.
• Before installation, make sure the head unit power switch is turned OFF.
• Disconnect the negative (-) lead at the battery before making any power connec¬
tions.
• 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 on the positive (+) power lead and connect it as close as
possible to the vehicle's (+) battery terminal. Use a rating that equals the total cur¬
rent 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 fire.
• Refer to Figure 9 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 yellow-insulated 10-
gauge (or larger) wire for the amplifier's positive {+) power lead and the same
gauge black insulated wire for the ground.
• A ring terminal cannot be used for the speaker output terminal and the power
source terminal. (The terminal screw has been designed not to come off.)
• When replacing the amplifies!? fuse, always use one having the same current rat¬
ing. 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. If you are planning to install a multi-ampli¬
fier system, you may need to add a second battery and possibly upgrade the
alternator with a higher-output-rated model. Consult your Clarion dealer for rec¬
ommendations.
-• To.avoidLpossihla 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 the 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 being 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 source unit or equalizer.
• Depending on the type of system being installed, refer to the examples in Figures
5 through 7 for information on wiring and setting the operation mode.
