This section lists Mounting and Wiring
Precautions for installing Cerwin-Vega! XL Series
amplifiers. 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 Cerwin-Vega! dealer
for installation recommendations.

MOUNTING PRECAUTIONS

Although Cerwin-Vega! XL Series amplifiers
incorporate 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
set-up, mount the amplifier so the front panel
controls will be accessible after installation. 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 enclosures 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 Cerwin­Vega! dealer.

1. Before installation, make sure the source

unit Power switch is in the OFF position.

2. Disconnect the negative (-) lead of the battery

before making any power connections.

3. When making connections, be sure that

each connection is clean and secure.
Insulate final connections with electrical

INTRODUCTION

Thank you for purchasing a Cerwin-Vega! car
audio amplifier. This power amplifier has been
designed to provide high quality performance
with a minimum of maintenance. However, it’s
performance will only be as good as the care
and quality of components with which it is
installed. We therefore advise that you read
these instructions very carefully to familiarize
yourself with the product and it’s features.

Before installing the power amplifier please read
this instruction manual carefully. The instructions
for mounting and connecting the unit have to be
followed precisely. If necessary, a service center
should be consulted.

All connections for DC power, signal input and
speaker outputs can be carried out easily and
safely by way of RCA, screw terminals and plug­in connectors.

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 Cerwin-Vega!
amplifier. Use the shortest ground wire
possible and securely connect to the car
chassis to minimize resistance and avoid
noise problems.

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 rating that equals the total
current consumption at full output of all
amplifiers in the system. This external fuse
will protect the vehicle from short circuits
that can cause a fire.

If the fuse blows, check the power connection and
replace the fuse. If the fuse blows again after
replacement, there may be an internal malfunction.
In this case, consult your dealer.

Warning

Use the specified amperage fuse. Use of a higher
amperage fuse may cause serious damage to the
amplifier.

Protection Circuit

This amplifier is provided with a protection circuit
which operates when:

- the unit is overheated or when the speaker
terminals are short circuited.

•This unit is designed for negative ground 12V
DC operation only.

•Total system impedance must not be less than 2
ohms.

• Avoid installing the unit where:

- It would be subject to high temperatures, such as

from direct sunlight or hot air from the heater.

- It would be exposed to rain or moisture.

- It would be subject to dust or dirt.

• Do not cover the unit with carpet or wires.

•This power amplifier employs a protection
circuit to protect the transistors and speakers if
the amplifier malfunctions. Do not attempt to
test the protection circuits by covering the
heatsink or connecting improper loads.

• Do not use the unit with a weak auto battery as

its optimum performance depends on a normal
battery supply voltage.

•For safety reasons, keep the volume of your car
audio system moderate so that you can still
hear normal traffic sounds outside your car.
