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 Hertz amplifiers.
Speaker cable recommendations
The table refers to continuous power into 4 Ω
load. If load decreases, cable size will have to
increase proportionally.
Power and Ground cable recommendations
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.
How to calculate your system
current consumption
TP x 2
I =
Vbatt
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 is 50% efficiency, as most
amplifiers today.
• Your electrical system is 12 Volt.

associated with poor system grounding.
3 FUSE HOLDERS:
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:
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 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.
