Batteries And High Output Alternators - Diamond D9 & TDX TECHNOLOGY Owner's Manual

Batteries and High Output Alternators...

The battery in your car is a chemical storage device for electrical energy generated by the
alternator. It is capable of briefly supplying high currents for cold starting the vehicle as
well as powering other important electrical loads either partially or entirely for a limited
period when the engine is off.
In order to supply the power required for ignition, lighting, large audio systems etc. a car
needs its own efficient, reliable, and constantly available source of energy. When the
engine is stopped, the battery is the vehicle's energy source. When the engine is running,
the alternator is the on-board "electricity generating plant." It is the job of the alternator
to supply power to all current-consuming loads (including the audio system).
Alternator output, battery capacity, and power demand of all electrical loads and systems
must be matched as ideally as possible so the entire system is reliable and trouble-free
in operation.
In the most basic of terms, this means that car audio is gasoline powered. Extra batteries
are primarily for the extended operation of your audio system when the engine is off, or
for SPL competitions where high sound pressure levels are generated for short periods of
time. In which large battery racks are needed to provide the necessary current demanded
by the many amps used.
D9 Series Amplifiers are capable of reproducing "concert level" volumes with incredible
accuracy. Care must be taken to ensure that your vehicle is capable of supplying the
voltage and current required by such a system.
D9 amplifiers are designed to accept up to 0Êgauge power and ground cable, in some
systems this may be overkill, but bigger is always better when it comes to power and
ground connections.
