5 Best RCA Cables For An Outstanding Car Audio Setup

When it comes to your in-car audio system, there are so many different components involved when setting up a complete system; it’s hard to keep track. Of course, you don’t want to spend all your money, just to realize in the end that you’re experiencing the quality sound that you were expecting.

The most important thing to remember is that every part of your system is just as important as the next. That ranges from your car audio radio and audio inputs stations, the amps you’re using, the speakers you’ve chosen, and, perhaps most importantly, the cables that are connecting it all together.

That’s right; while many of us are happy to fork out for a premium range of speakers and in-car radios, failing to pay attention to what cables you’re usingcan hold you back when it comes to your soundsystem performing to its best.

The cables you choose will determine the overall quality of sound between each piece of equipment. In short, if you’re using a low-grade cable, you’re going to achieve a low-grade result. While many speakers, radios, and amps will come with a set of cables for you to use, purchasing premium quality cables can make dramatic changes to your sound.

Today, we’re going to explore the world of RCA cables, seeking out the best of the best with the aim to make it easy for you to pick the one that’s right for you. We’ve taken all aspects of RCA cables into account, narrowing the market down to just five fantastic options which guarantee to bring your in-car soundsystem to life.

To start with, we’ve opted for a great all-around RCA cable that ticks the boxes for being both affordable and providing you with a high-quality sound experience. This male to male RCA cable measures in at 15-foot long, which is more than enough to ensure that it will reach around each area of your vehicle.

However, this particular brand does offer a range of sizes to suit you from 3-foot to a whopping 25-foot. What helps this cable to provide such a great signal is the fact that the connectors are plated with 24-karat gold.

Not only does this help you cables to resist forms of corrosion and damage from everyday wear and tear, but also to maximize the effectiveness of the connection. This level of quality continues thanks to the copper braided, aluminum foil shielding that coats the interior of each cable.

This ensures that the cable is super flexible and resistant to breaking when you bend it, but it also helps to block out unwanted noise and EMI/RFI interference which is common with cheap cables.

With a tin-plated copper core to stop oxygen disrupting your signal and polyethylene foam for dielectric insulation, this cable is surely everything you’ve been looking for.

  • 24-karat gold plated connectors for optimal sound quality
  • Copper-braided, aluminum foil interior shielding
  • Tin-plated copper core for minimal oxidization and longer cable lifespan
