1 BATTERY CLAMPS: ensure high current
transfer without the power robbing consequences
of a high resistance connection.
2 GROUND TERMINALS:
minimizing
resistance and the consequent power losses
associated with poor system grounding.
3 FUSE HOLDERS:
are the first line of
protection for your vehicle and yourself from
dangerous short circuits. The high temperature
case and waterproof construction ensure reliability
in any environmental condition.
4 POWER & GROUND CABLES: are of
fundamental importance to obtain reference
performance in your car audio/video system.
The special structure of Main Power and Power
Flow cables minimize eddy current power losses
and allow high instantaneous current transfer,
enabling you to experience the full dynamics
of your music.
5 FUSE DISTRIBUTION: their name tells you
their function: transferring energy to electronic
devices. They are available in various models,
even modular, and they can house the protection
fuse. Fuse distributions are to be used in every
system where you need to transfer a huge amount
of current without losses.
6 GROUND DISTRIBUTION BLOCKS:
are as important as the power distribution to
your systems overall performance. Solid, low
resistance ground points prevent harmful
voltage differences between components and
improve high-level current transfer without
power loss.
7 SUPERFARAD
TM
: capacitors act as a
“current reserve” storing DC energy for when
your amplifiers demand it the most.
8 AUDIO INTERCONNECTS: are the
first component in your system that audio
signals pass through. For faithful reproduction,
they must transfer these signals from the
head-unit to the amplifiers without modifying
the sound, while at the same time, reject the
tremendous amount of noise radiated by
on-board computer-controlled devices in your
automobile.
9 VIDEO INTERCONNECTS:
provide outstanding picture detail, definition
and color balance. With constant 75-ohm
impedance and outstanding shielding,
stunning picture quality is assured.
10 SPEAKER CABLES:
provide that last
step in the faithful reproduction of your music.
They ensure the transfer of music to your
speakers without the coloration or degradation
of the signal.
How to calculate your system
current consumption
I =
TP x 2
Vbatt
I = = 108,3 A Current consumption
650 x 2
12
I = Current consumption of your system in
ampere (A);
TP = Total power (RMS) of channels of all
amplifiers in your system;
Vbatt = Usually value is 12 V, the nominal
automotive electrical system voltage.
Example:
• Your total system power (RMS) of all channels
in all amplifiers is a combined 650 W.
• Your amplifier average 50% efficiency, as most
amplifiers today.
• Your electrical system is 12 Volt.

Connection cables
For maximum performance, always use new, good quality cables; their outer jacket must not be
spoiled, and the copper must not show oxidation. For proper operation, always consider the length
of the connection, the load and the current it has to handle.
CONNECTION Audison products are the most flexible and complete; they are designed and built in
order to get the best out of every installation, especially when used with Audison amplifiers.

The table refers to continuous power into 4 Ohm
load. If load decreases, cable size will have to
increase proportionally.

If you don’t know your system current consumption, find it using the mathematical formula below
and find this same value on the left hand column of the table. Then calculate the length of your
connection and find this same value on the bottom column of the table. At the point where these
two values cross is the minimum section in gauge (A.W.G.) which CONNECTION recommends for
building a high performance, reliable system.
