What is the big 3 car audio?
The Big Three wiring upgrade This upgrade replaces or augments three key cables in the electrical system with 1/0 or 4 gauge wires: the battery ground to chassis wire, the chassis to engine block wire, and the alternator plus to battery plus wire..
How can you tell if a wire is tinned copper or aluminum?
You can pretty much tell if it’s tinned copper when it’s old cloth sheathed wiring like in the photo. Majority of branch circuit aluminum wiring is from the 70’s and is plastic sheathed. When I’m not sure I turn the breaker off and pull the wire out to look at the cut end.

Why is oxygen free copper used for high conductivity?
Oxygen-free high thermal conductivity The method of producing OFHC copper ensures an extra high grade of metal with a copper content of 99.99%. With so small a content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree.
Does oxygen free speaker wire make a difference?
According to tests, oxygen-free copper also runs cooler than other conductors. It’s more resistant to shorts, more durable and long-lasting, and is far less likely to corrode, due to the reduced oxygen content—at least, that’s the common wisdom.
How can you tell the difference between OFC and CCA?
CCA or OFC Amplifier Wiring? There’s a big difference between copper-clad aluminum (CCA) and oxygen-free copper (OFC) wiring. First of all, aluminum conducts 61% of the electricity that copper conducts, meaning that you’ll need a thicker aluminum wire and it will produce more heat.
What is CCA speaker wire?
‘CCA’ is Copper Clad/Coated Aluminum wire. This is ALUMINUM wire with a very thin coating of copper. … This means to carry the same load, you’d have to use a significantly heavier gauge wire, which can eliminate much of the cost savings.
How can you tell real copper wire?
The common method of identifying fake copper wire is to scratch the wire deeply with a sharp knife. If the inside appears to have any other color other than the one seen on the outer surface of the wire then it was electroplated and hence may be a fake wire.
What gauge speaker wire should I use?
Thick wire (12 or 14 gauge) is recommended for long wire runs, high power applications, and low-impedance speakers (4 or 6 ohms). For relatively short runs (less than 50 feet) to 8 ohm speakers, 16 gauge wire will usually do just fine. It’s cost-effective and easy to work with.
Is CCA speaker wire any good?
From a conductor point of view, CCA is OK but it needs to be larger than a copper conductor. Say 12AWG CCA to 14AWG copper (and maybe more). Attaching connectors may be a real world problem. As for expensive OFC compared to wire copper the difference it trivial!
How do I know what CCA cable I have?
According to Peri, a more effective method for identifying CCA is to snip off a piece of the cable to expose the conductor, then scrape it with a knife to remove the top layer of copper. If there’s a silver color beneath, that indicates the presence of aluminum.
Can you solder CCA wire?
Its Copper Clad Aluminum. It can be soldered, crimped, and generally used the same as Copper Clad Copper except the copper wire gauge guidelines should be revised for it.
How many watts can 1 0 gauge handle?

What does OFC wire mean?
Oxygen-Free CopperTwo standard types of wire for car audio are CCA (Copper-Clad Aluminum) and OFC (Oxygen-Free Copper). … You need to see it head-on in order to see the aluminum in the center. It’s less expensive than a wire that’s made up entirely of copper such as OFC. It’s also lighter than pure copper wire.
What is CCA?
CCA is a rating used in the battery industry to define a battery’s ability to start an engine in cold temperatures. … The higher the CCA rating, the greater the starting power of the battery.
What is 4n OFC?
Silver Plated 4N OFC Copper 0.5mm² This cable is ideal for internal wiring. It incorporates very high purity OFC 4N copper conductors and silver plating to ensure excellent conductivity.
Is CCA wire bad?
Higher resistance causes radiant heat to build up faster, and this may cause damage to the device. On longer CCA cable runs near the 100-meter maximum, signal strength is reduced as compared to solid copper Category 5e. This can lead to data loss as a result of more packets of data needing to be retransmitted.
