Our speaker cables are made with high-quality materials and are 100% oxygen-free pure bare copper, which provides excellent conductor performance and lowers resistance in speakers for premium sound quality. They are also CMR/CL3R rated, making them safe and secure for in-wall installations in the home or office, and they are UV protected for use in outdoor direct burial applications. The cables are UL listed and RoHS compliant, and they are available in a variety of sizes and conductor counts. They are flexible and easy to use, with a PVC jacket and a ripcord for easy stripping.
16/4 speaker wire is a type of electrical cable that is commonly used to connect speakers to an audio amplifier or receiver. The "16/4" designation refers to the size of the wire, with the first number indicating the gauge (or thickness) of the wire, and the second number indicating the number of individual conductors (or "strands") within the wire. In this case, the wire has a gauge of 16 and is made up of four separate conductors that are twisted together. This type of wire is often used for applications where the distance between the amplifier and the speakers is longer, or where the speakers require more power to operate. The four conductors are typically color-coded to make it easy to identify the positive and negative leads for each speaker.

Infinity Cable Products prides itself on offering the highest quality products possible. Our 16/4 Speaker Wire is tried and tested to ensure performance and compatibility.

Q: What does 16/4 speaker wire mean?
A: 16/4 speaker wire contains four individual 16 AWG conductors within one cable jacket. The four conductors can support two speakers or one speaker installation that requires separate connections.
Q: When should I use 16/4 instead of 16/2 speaker wire?
A: 16/4 speaker wire is useful when connecting two speakers from one cable run, wiring stereo volume controls, or simplifying multi room and whole home audio installations. 16/2 cable contains only two conductors and is commonly used for a single speaker.
Q: What is the difference between CL3R and standard CL3 speaker wire?
A: CL3R speaker wire is approved for both vertical riser installations between floors and standard in wall applications, while standard CL3 cable is only rated for general in wall use. This gives CL3R greater installation flexibility for residential and commercial audio projects.
Q: Can this speaker wire be installed outdoors or underground?
A: Yes. The UV protected jacket is designed for outdoor use, and the cable is rated for direct burial applications. Always follow local installation requirements and protect connections from moisture.
Q: Why is oxygen free copper important for speaker wire?
A: Oxygen free copper provides excellent conductivity and lower electrical resistance compared with copper clad aluminum, helping deliver reliable audio performance and long term durability.
Q: Why does this cable use stranded conductors?
A: Stranded conductors make the cable more flexible and easier to route through walls, ceilings, conduit, and tight spaces while maintaining a dependable connection.
Q: Can 16/4 speaker wire be used for two speakers?
A: Yes. The four color coded conductors can be divided into two positive and negative pairs, allowing one cable run to connect two speakers when the system design supports it.
Q: What applications is this speaker wire commonly used for?
A: This cable is commonly used for home theaters, whole home audio, in wall speakers, in ceiling speakers, outdoor speakers, stereo volume controls, commercial audio systems, and distributed sound installations.
Q: Can this cable be used with banana plugs and binding posts?
A: Yes. This speaker wire is compatible with common connection methods including banana plugs, spade connectors, pin connectors, binding posts, spring clips, and direct wire terminals.
Q: What do the different conductor colors mean?
A: The four conductors are color coded to make it easier to identify each positive and negative speaker connection during installation. Use the same color assignment at both ends of the cable.
Q: Does this cable include a ripcord?
A: Yes. The integrated ripcord helps installers open the outer jacket more easily while reducing the risk of damaging the insulated conductors.
Q: Is this speaker wire suitable for professional installations?
A: Yes. This 16/4 speaker wire is trusted by audio installers, low voltage contractors, home theater professionals, and commercial integrators for residential and commercial speaker installations.
