Connection Cables; Speaker Cable Recommendations; Power And Ground Cable Recommendations - Hertz HP 1D Advanced Manual

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
Ohm 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.
650 x 2
I = = 108,3 A Current consumption

system where you need to transfer a huge amount
of current without losses.

tremendous amount of noise radiated by
on-board computer-controlled devices in your
automobile.
