What to Consider When Buying the Best RCA Cables for Car Audio

RCA cable’s looks and application are straightforward. You take the cable and plugin it in a suitable color female port of the TV, DVD, Playstation, Xbox, etc. However, consider a few factors before buying an RCA cable for car audio.


The RCA cables you will install will not be visible once you are done fitting the music system in your car. An RCA cable passes an audio signal, which can be affected by electromagnetic interference, resulting in a distorted audio output.

It is advisable not to purchase RCA cable with thin wires; instead, go for a braided or spiral shielded wire. The type of mentioned shielding not just prevents frequency interference but also provides good durability and reliability.

Length of Wire

It is important. Long RCA cables will result in poor signal transmission. Only pick long wires if required. Otherwise, pick RCA cables according to the requirement to get the best audio output experience.

Connector Material

Gold, silver, and copper are used to manufacture the male connector pins.

The gold connectors look excellent, demand less maintenance, and are corrosion-resistant; however, they are not the best at conducting electricity.

Silver is the best connector. It requires nominal caring and is the finest material for conducting electricity, respecting the types of material from which RCA cable pin connectors are manufactured.

If you want long-lasting cable, RCA cable with gold material connectors is best, and if you seek a balance of quality audio and good build quality, silver is the value for money.
