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 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
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 is 50% efficiency, as most
amplifiers today.
• Your electrical system is 12 V.
