Speaker Wire

Speaker wire is the backbone of clear, reliable audio, linking amplifiers and receivers to bookshelf speakers, towers, and subwoofers in home theater, studio, and car audio systems. The right cable preserves detail, reduces signal loss over distance, and withstands bends, heat, and frequent moves.

Choose gauge by run length and power. Use 12 AWG for long runs or high‑power and subwoofer feeds, 14 AWG for most rooms up to roughly 50–75 feet, and 16 AWG for short runs or satellites. Oxygen‑Free Copper (OFC) offers low resistance and longevity; Copper‑Clad Aluminum (CCA) is lighter and budget‑friendly but higher in resistance. High‑strand counts improve flexibility and contact area. Look for clear polarity markings or color coding to avoid phase errors.

Match construction to the job. CL2/CL3 and UL‑rated options are designed for in‑wall or in‑ceiling installs; plenum‑rated (CMP) jackets are for air‑handling spaces. Outdoor and direct‑burial cable features UV‑resistant, moisture‑blocking jackets. Two‑conductor wire covers most speakers, while four‑conductor simplifies bi‑amping, bi‑wiring, or multi‑room runs. Twisted‑pair designs help minimize hum in electrically noisy spaces.

Plan the install: measure the path, add slack for service loops, and avoid running parallel to AC lines—cross power at right angles. Use wall plates and banana plugs, spade lugs, or pin connectors for neat, secure terminations. Bulk speaker cable on spools supports custom lengths; pre‑terminated leads speed quick setups.

Before you buy, confirm total length, gauge, jacket rating, and connector style. Consider color, labeling, and heat‑shrink for easy identification. Properly chosen and installed speaker wire delivers tighter bass, cleaner highs, and consistent volume across channels.
