Buying Guide: Speaker Wires for Cars

Speaker wire for cars isn’t something you frequently shop for, which is why you should do careful research to avoid any bad purchases. This comprehensive buying guide covers some essential information to help you choose the ideal speaker wire for your needs.

Factors To Consider When Shopping for a Speaker Wire for Cars

Material

Copper wires are the ultimate choice for car speaker wires as they deliver data transmission effectively. They can be quite expensive, however. An affordable substitute for pure copper wire is copper-clad aluminum wire, which is lighter and does the job perfectly well. Also, ensure that the speaker wire is PVC coated since this adds to its durability and safety. 

Gauge

The gauge of a speaker wire for cars refers to the thickness of the wire, with a lower gauge being thicker and a higher gauge being thinner. A lower gauge can carry more data from amplifiers to speakers, making them better for car speakers. That’s why we recommend you go with a lower gauge. 

Length

Speaker wires for cars usually come in plastic spools of different sizes. The size of your spool means the length of the wire in feet. The wires are available in different sizes ranging from 50 feet to 500 feet. Make sure to measure your required size before buying one. 

What Are the Benefits of a High-Quality Speaker Wire for Cars?

Lower distortion

High-quality speaker wires for cars can lower the distortion to an insane extent. This is because a speaker wire that easily corrodes can cause unpleasant noise and distortion while delivering poor sound quality. Rewiring the stereo is the usual solution to this problem, so investing in a durable and long-lasting speaker wire can help save you from having to do this often. 

Improve performance

If you feel like your car speakers aren’t responsive, rewiring the stereo can solve the problem. Since speaker wires for cars are made of copper, they excel in conductivity and transmit signals smoothly. This way, neither the sound quality nor volume would be affected.
