Introducing the Southwire 250 ft. 16/2 Stranded Audio Speaker Wire—an expert-grade cable built to power reliable, higher-fidelity speaker runs both inside the home and outdoors. With two stranded copper conductors and a robust thermoplastic insulation, this wire is designed to deliver clear, consistent audio signals across a range of setups.
-
Length and configuration: 250 feet of 16/2 stranded audio speaker wire, two conductors tuned for clean stereo or mono speaker runs.
-
Conductor material: Pure copper strands for flexible, low-resistance transmission and dependable conductivity.
-
Insulation and jacket: Thermoplastic PVC insulation paired with a durable poly jacket to resist abrasion and stand up to practical installation conditions.
-
Direct burial capability: Rated for direct burial, making it a solid choice for landscape or exterior speaker installations without the need for conduit in every run.
-
Safety and compliance: UL-listed for safety, giving you confidence in performance and compliance for residential or commercial projects.
-
Flame retardant: Flame-retardant jacket provides an extra layer of security in environments where heat or electrical arcing could be a concern.
-
Amp and voltage ratings: Amp rating up to 10 amps and voltage rating up to 30 volts, suitable for most standard low-voltage speaker applications.
-
Temperature tolerance: Designed to perform reliably up to 75°C, helping maintain signal integrity in warmer spaces and during extended runs.
-
Indoor/outdoor versatility: Built for both indoor and outdoor use, giving you flexibility to route the wire through living spaces, patios, or yards without mismatch.
Why this wire stands out
Unlike generic speaker cables, this Southwire 16/2 stranded wire is purpose-built for lasting performance in real-world environments. The stranded copper design enhances flexibility, making it easier to pull through walls, conduits, or outdoor trenches while reducing the risk of kinks and breakage over time. The combination of thermoplastic insulation and a poly jacket means the cable can withstand everyday wear, UV exposure to the extent applicable by its design, and moisture exposure when installed as directed for outdoor use.
Ideal use cases
Perfect for:
- Outdoor patio or backyard speaker systems where direct burial is permissible, reducing the need for heavy conduit runs.
- Indoor home theater or stereo setups requiring a reliable, long-running low-voltage speaker connection.
- Landscape or garden installations where a robust, flame-retardant, UL-listed cable adds peace of mind.
Practical tips for getting the most from this cable
- Plan runs to minimize voltage drop over long distances; for longer paths, consider higher gauge or multiple shorter segments with proper connectors to preserve audio quality.
- Use terminals and pluggable connectors rated for 16 AWG to ensure secure, corrosion-resistant connections.
- When burying directly, follow local codes and keep the burial depth compliant with your installation plan; use protective conduit where required by code or physical hazards.
- Keep conductor pairs neatly paired and avoid sharp bends or kinks that could damage the insulation or constrain signal transmission.
- Label each run for easy maintenance or future upgrades—clear labeling helps when expanding a system or relocating speakers.
