MOUNTING THE AMPLIFIER
When planning where to install your amplifier, you
must first think in terms of keeping the amplifier cool
enough to function properly. Amplifiers are heat-
sensitive. This means that the operating parameters
may change with fluctuations in temperature and an
amplifier can literally be destroyed by excessive heat
during operation.
All audio amplifiers are only about 60% efficient.
They work in a linear mode so 40% of the power de¬
livered to the load is eaten up in inefficiencies of the
amplifier and lost in heat. The more you push an
amplifier, the more heat you must get rid of.
The finned outer surface of the amplifier is diheat
sink which helps to carry heat away by means of
thermal conduction. Therefore, you must allow the
amplifier to breathe so that the heat sink can best
do its job.
• Don't put a glass or metal cover over the top of
the amplifier unless you have a cooling fan at one
end.
• Keep In mind that any moving air dissipates heat.
• If possible, duct the car air conditioning system
so that cooling air is directed along the fins of the
amplifier heat sink.
• Cooling air should be directed along the fins rather
than across them for the most efficient cooling.
• Don't mount the amplifier on plastic or use a
plastic cover. The plastic will melt.
Once you have selected the mounting location,
mount the amplifier using the four self-tapping screws
provided. Tighten the screws securely.
CAUTION
Be very careful not to drill into the fuel tank, fuel
lines, or through electrical wiring.
It is always best to mount the amplifier flat on
the floor under the front seat or in the front of the
car trunk. Remember heat travels up,
