RECOMMENDATION
A power amplifier’s performance is only as good as its installation. Proper installation will
maximize the system’s overall performance. It is recommended that you have our product
installed by an authorized QUANTUM AUDIO retailer. However, if you decide to install it
yourself, please carefully read through this manual and take your time to do a quality instal-
lation.
Due to continuing product improvements and possible manual revisions, we recommend
checking our website for latest product information at www.quantumaudio.net.
IMPORTANT! Before making any connections, disconnect the car’s battery until the
installation is completed to avoid possible damage to the electrical system.
WARNING!
Exposure to high power sound system can cause hearing loss or damage.
Listening to your system at loud levels while driving will impair your ability
to hear traffic sounds and emergency vehicles. Use common sense when
listening to your system.

SAFETY PRECAUTIONS
Fuse amplifiers power wire at the battery
Be sure to fuse the power wire within 12” of the car’s battery. This will protect the car’s
battery in case of a short circuit between the power amplifier and battery. THIS IS A MUST,
the amplifier’s built-in fuse will only protect the power amplifier not the car’s battery!
Use high grade wire connectors
To ensure maximum power transfer and secure safe connections, it is recommended to use
high grade barrier spades (for connection at amplifier) and terminal rings (for connection at
battery).
Do not run any wires underneath vehicle
Exposed wires have a chance of being cut or damaged. It is best to run all wires through the
vehicle under the carpet and/or side panels. This leads to a cleaner installation and less risk
of damage.
Use caution when mounting amplifier
Remember there are many electrical wires, gas lines, vacuum lines, brake lines as well as
a gas tank in the automobile. Make sure you now where they are when mounting the ampli-
fier to avoid puncturing lines, shorting wires or drilling holes in the gas tank.
Run signal wires away from electrical wires
To avoid possibility of induced noise from the car’s electrical system (i.e. popping noises or
engine noise), run wires away from the car’s electrical wiring.
Make all ground wires as short as possible and at the same point
In order to reduce the chance of ground loops (i.e. engine noise), make the grounding wire
as short as possible to reduce the wire’s resistance. Also, when using multiple components,
make sure all units are grounded at the same point.
Avoid sharp edges when running the wires
To avoid the possibility of power, signal or speaker shorts, be careful not to allow the amplifi-
ers wires to come in contact with sharp edges. Use a grommet to protect the wire when
running through the fire wall.
