RCA cables used in a vehicle audio system must be shielded from the disturbance and vibrations caused by both the computerized parts and the mechanical components in contemporary cars.

Shielding prevents these exterior electrical signals from impacting on the sound. RCA cables are long lasting and affordable, which is why you need the best RCA cables for your car audio.

How Do They Work?

The RCA cables provide a connection between your Smartphone and your car’s speakers, making it possible to listen to music from your phone through the speakers.

There are several options available in the market, and a brief review will help you make an informed decision.

What To Consider When Buying RCA Cables For Car Audio

RCA cables for car audio will be exposed to a lot of stress and interference. To ensure that the RCA cables you get can withstand the rigors of use on the inside of a vehicle and work well for a long time, pay attention to the following features and specifications when making your choice.

Sound Clarity

The best RCA cables for car audio should transmit sound in a very clear way. Hissing and popping sounds should not be heard from the speakers.

Good RCA cables deliver crystal-clear sound by reducing interferences and static noise and ensuring the signals flow efficiently.

Poor quality RCA cables, on the other hand, are susceptible to interferences. They can pick up noises and ruin the sound quality.

Rigidity

While it is important that the cables are strong and rigid, they should not be so stiff that they risk breakage with repeat use.

Flexible cables also provide room for maneuverability eliminating the need for extra-long RCA cables.

Additionally, the connectors should attach well to various devices without being too loose or too tight. This will prevent the loss of signals and ensure there's no distortion of sound.

Size

It is important to consider the length of the cables when purchasing. Depending on your needs, you can select from very short to very long cables from the available brands. RCA cables come in lengths ranging from 3 to 25 feet.  

That being said, short to medium-length cables deliver the best audio quality. The cables should be just long enough to go from the source of audio to the amplifier. Keeping the cable as short as possible ensures efficient signal transfer and high-quality audio output.

Quality

Always match the quality of the cables you buy to the quality of the devices that you will be using the cables on. High-quality RCA cables provide excellent value for money in terms of both performance and durability.

Using low-quality cables on high-quality devices may be cheaper in the short run, but you will not get the best performance and value for money. Furthermore, using substandard cables may damage your devices in the long run.

Double Shielding

When used with a car audio system, the RCA cables will be under constant pressure from the vibrating engine. They will also be subjected to sudden shocks whenever you hit a bump on the road, accelerate, or brake.

Not only should the cables be strong enough to not break easily, but shielding is also essential to protect the wires inside the cables from damages and the signals from interference. For the best quality signals, go for RCA cables with dual-shielding.

Dual-shielded RCA cables use braided copper shielding to prevent radio frequency interference (RFI) and aluminum foil shielding to keep electromagnetic interference (EMI) at bay.

Materials

The materials the cables are made of determine the performance as well as the durability of the cables. Pay attention to the following parts of the cables:

  • 24k gold-plated connectors are ideal. Pure gold provides top-notch signal transfer and is resistance to corrosion and tarnishing. Silver-coated connectors also have excellent signal transfer but they are susceptible to corrosion, which makes them less than ideal.
  • Use of an insulator such as polyethylene foam in between the conductor and the shielding is essential to prevent loss of signals and ensure you enjoy crystal-clear sound output.
  • Finally, the core of the RCA cables for car audio should be plated with tin. This coating slows down oxidation and prolongs the life of the cables.
