100% OFC COPPER CABLE
Why choose OFC cable for an amplifier?
In a Car Audio installation, the power cable must carry
the current required for the amplifier to operate. OFC copper
offers high electrical conductivity and, with a properly
sized gauge, can efficiently power audio systems
requiring a high current.
OFC cable
OFC cable uses high-purity copper. It is particularly
sought after for demanding Car Audio installations, powerful
amplifiers, and systems requiring properly
sized power supply.
OFC or CCA?
CCA cable uses copper-clad aluminum, while
OFC uses copper. With the same gauge, their electrical
characteristics differ. For high-power installations,
OFC cable is generally preferred.
CAR AUDIO INSTALLATION
Battery, amplifier, and ground cable
Amplifier power cable
The positive cable delivers power from the battery to
the amplifier or a distribution block. Its gauge must be
suited to the electrical draw of the system and the length
of the cable.
Amplifier ground cable
The ground is an integral part of the power circuit.
It must be properly sized and connected to
create an electrical installation suited to the amplifier.
OFC CABLE GUIDE
Which OFC cable gauge should I choose?
There is no universal gauge for all amplifiers.
The choice depends mainly on the required current, the length
of the cable, and the configuration of your installation.
✓ Amplifier — model used
✓ Power draw — required current
✓ Length — battery / amp distance
✓ Gauge — 10 to 70 mm²
✓ Ground — properly sized
✓ Fuse — cable protection
Unsure between 20, 35, 50, or 70 mm²?
Contact Sound Auto Concept with your amplifier model,
the power of your installation, and the approximate length of the cable.
We can help you choose a suitable gauge.
HIGH-POWER CAR AUDIO
Large-gauge OFC cable for powerful installations
For powerful monoblock amplifiers, SPL installations,
multi-amplifier systems, or configurations requiring a lot
of current, large gauges such as 35, 50, or 70 mm² can
be used when the electrical sizing of the installation
requires it.
FREQUENTLY ASKED QUESTIONS
FAQ – Car Audio OFC Cable
What is OFC cable?
OFC stands for Oxygen Free Copper. It is a high-purity
copper conductor commonly used for wiring audio and
Car Audio installations.
What is the difference between OFC and CCA cable?
OFC cable uses copper, while CCA is primarily made
of copper-clad aluminum. Since their conductivity differs,
the same gauge does not necessarily have the same
electrical characteristics.
What cable gauge is needed for a car amplifier?
The gauge must be determined by the electrical draw
of the amplifier, the length of the cable, and the type of conductor.
More powerful installations generally require
a larger gauge.
What OFC cable is needed for a 1000 W RMS amp?
RMS power alone is not enough to precisely choose
the gauge. You must also consider the efficiency,
the maximum power draw of the amplifier, and the length
of the power cable.
When should I use 35 mm² OFC cable?
35 mm² is used in various installations requiring
a significant power supply. However, its suitability depends on
the required current and the length of the wiring.
When should I use 50 mm² OFC cable?
50 mm² cable is commonly intended for Car Audio installations
requiring a high power supply capacity. Sizing
must always be done according to the actual electrical requirements.
What is 70 mm² OFC cable used for?
Very large gauges such as 70 mm² are intended for
installations requiring a particularly high current,
especially certain high-power Car Audio configurations.
Are OFC cables sold by the meter?
Yes. Cables in this collection are sold by the linear meter.
For example, a quantity of 4 corresponds to a continuous
4-meter piece of cable.
Can OFC cable be used for an amplifier ground?
Yes. A properly sized OFC cable can be used
to create the ground connection for a Car Audio amplifier.
