Improving a car’s audio quality can make drives around town or longer road trips much more enjoyable. Many people find success in older cars by installing a car antenna extension cable to pick up higher quality radio signals.
Another, more effective, way to improve car audio is to connect a high-quality RCA cable to your speakers.

It’s flexible as well, like its sister models. There’s a cable strap attached to the cord so you can store it away when you’re not using it.
Due to the 25-foot length of this cable, you might experience some hum. Sometimes the plug can be a little tight. If you’re not pleased with the sound, never fear! Mediabridge’s ULTRA series comes with a limited 1-year warranty.

Skar Audio 17 Ft. 2-channel features twisted pair technology that makes for a more stable signal. It also utilizes the 99.99% oxygen-free multi-strand copper wire construction another thing that helps the signal transfer. The cable is flexible and the shielding is high quality. You get a 2-year limited warranty with the cable.
This cable doesn’t have the cleanest sound it is also a bit loud, some times it can whine. The sound issue might be connected to weak isolation. Also, the plugs look like they are on the weaker side.
Best Premium RCA Cable
Better Cables uses a high-quality silver coating to conduct a better sound signal than gold or copper. The ends are not soldered but cold-welded to the cable. The company offers a 30-day money-back guarantee on all products.
Sound depends mostly on your setup, these cables work with some devices better than others. If you have revealing speakers or a high-grade amp, you might find that the cords produce high frequencies that cause headaches in some people.

Honorable mention
Blue Jeans Cable has 3-foot, 6-foot, 10-foot, or 15-foot composite cables to choose from. The low capacitance feature of 12 pF for each foot of cable helps to lessen the chances of high-frequency roll-off. The double bare copper braid shielding lessens the chances of EMI rejection (negates interference from other cables).
Even after grounding, there can still be a humming sound. So if you notice any interference like that, there is a 30-day money-back guarantee that comes with your Blue Jeans Cable purchase. Additionally, these cables are a bit stiff. If you are not happy with your cable, send it back for a full refund.
