Buying Guide to Choose the Best RCA Cable for Car Audio

RCA audio cables/connectors are used to transmit the audio signals from the car head unit to the speaker or amplifier. To make your purchase worthwhile, you need to consider some key factors that help you to differentiate and pick the correct RCA cable from numerous car audio RCA cable options on the market.

Before getting into the topic, here is a clear explanation of RCA cables and how it impacts car audio.

The RCA is referred to as the Radio Corporation of America. This RCA connector is also known as a Phono Connector, in which the company has designed to carry audio/video (A/V) signals, and this technology is developed in the 1940s. This audio cable has a distinctive red, yellow, and white color that is widely used in car audio systems.

RCA cables transfer the audio signals from the source unit (like a CD player or head unit) to speakers or amplifiers. It comes with two connectors – one for the right and one for the left channel and has to plug the connectors properly into the corresponding inputs on the amplifier and source unit, especially used in the car audio system.

Then the amplifier boosts the signal sent to the speaker and allows it to be amplified and play at a higher volume with improved clarity in the sound. So, the RCA cables are an essential part of the car audio system that impacts the overall sound quality by transferring the audio signal from the source unit to the speaker or amplifier.

If you choose a car audio system with a high-quality RCA cable, then it has a clean and accurate audio signal, resulting in better sound quality and enhanced performance. Whereas, an audio system with poor-quality RCA cables will result in certain issues like signal loss, interference, and noise that negatively impact the sound quality.

Let’s get into the details of what factors to consider while shopping for RCA audio cables.

1. Type

There are two different types of RCA audio cables – composite and component. Composite RCA audio cables transmit a single audio signal (mostly stereo), whereas component RCA audio cables transmit multiple audio signals (mostly surround sound systems). So, it is crucial to choose the type of RCA audio cable based on your car’s audio system.

2. Connector Materials

The connector material of an RCA audio cable will determine the reliability and the audio quality. Usually, the connector is made of various materials like gold-plated, silver-plated, or nickel-plated. The gold-plated connectors offer better connectivity and resist corrosion. The nickel-plated connectors will offer connectivity (less than gold-plated), yet they are budget-friendly. Whereas, the silver-plated connectors improve conductivity and enhance the overall audio quality, making it mostly used/found in high-end RCA audio cables.

So, choose the connector material of the RCA audio cable based on your audio requirements, budget, and the car’s environment.

3. Length of the Cable

The RCA cable length you choose should be apt for the installation location but not be too long or too short. It should be sufficient to connect the source (car’s audio head unit) to the speaker or amplifier. A long cable won’t always be the best option because it results in signal loss and thereby reduced sound quality, while a short cable won’t allow for proper connection. So, choose a cable whose length is quite sufficient enough to connect the unit yet not excessive.

4. Proper Shielding

Shielding in RCA audio cables will minimize interference from other electrical devices in the car and ensure clear audio quality. Spiral, braid, and tape shields are common shielding types used in RCA audio cables. The cable with spiral shielding will reduce electromagnet interference (EMI), and braid shielding provide good protection from interference. While tape shielding offers sturdy & consistent protection against interference, making them quite useful for high-frequency applications.

Based on your required level of protection, and the interference type encountered in the car audio system, you need to select the best shielding for the RCA audio cable.

5. Conductor Material

The conductor material in the RCA audio cables will impact the signal strength and audio quality. It can be made of copper, silver, and oxygen-free copper (OFC). Among them, copper is the most preferred and common material used in the construction of conductors that offers good conductivity and affordability.

Silver metal provides enhanced conductivity, while oxygen-free copper (OFC) offers improved signal clarity. Thus, both these options are used widely in high-end RCA audio cables. So, choose and check the signal strength and the type of audio quality when choosing the conductor material for the RCA audio cable.

6. Durability & Compatibility

The RCA audio cables you choose should be compatible and durable with the existing car audio system. For this, you need to consider the car’s environmental conditions and select the cable that easily withstands high temperatures and vibrations.

7. Cost

Usually, RCA audio cables are available at different price ranges from $5 to $100, and you need to choose a good-quality cable that comes within your budget. Though high-end RCA cable offers improved audio performance yet they are expensive to purchase. So, check the RCA audio cables that fulfill your requirement and come in your budget range as well.

To conclude, it is essential to consider all these key factors for selecting the best RCA audio cable for your car audio system. Thus, the cable you purchase is compatible with the system and allows you to experience exceptional audio performance in your vehicle to enjoy the ride.

So, the RCA cable is not at all same as the Aux cable.

4. How do high-quality RCA cables make a difference in car audio?

Ans: A high-quality analog RCA cable will make even a slight difference in the car audio because this high-quality cable has better shielding, enhanced connections, and decent cable length making it reduce the effect of external interference. So, it enhances the overall connection and sound quality in the car audio compared to the low-quality RCA cables.

5. How to hook up a subwoofer with RCA cables?

Ans: You can easily hook up a subwoofer with an RCA cable by plugging it into the subwoofer output on the back of the receiver. Usually, RCA cables are used for audio and video transmission, while subwoofer cables are a type of RCA cable with some tweaks and upgrades. Thus, you can use 2 sets of RCA cables to connect the subwoofer and amplifier.
