KeyLine Chargers 12-Gauge Speaker Wire 100ft Black

KeyLine Chargers 12-gauge speaker wire is a 100-foot, 12-2 AWG copper-clad aluminum (CCA) cable built for indoor, in-wall and outdoor direct-burial speaker and low-voltage power runs.

This 12 GA 100-foot spool combines high-strand-count construction with CL3 in-wall rating and direct-burial durability so you can run sound and low-voltage power cleanly across home theater setups, outdoor patios, marine decks and vehicle audio installations. The cable is two-conductor 12-2 AWG with 180 high-count strands of CCA for a balance of conductivity, flexibility and cost-effectiveness when compared to pure copper alternatives.

Can I bury this wire outdoors or run it in wall cavities?

Yes — the cable is designed for both underground burial and in-wall installation. It carries UL CL3/CL2-style ratings appropriate for low-voltage speaker and audio lines, and the jacket is formulated to resist moisture and soil contact for outdoor runs.

• Direct-burial rated jacket for underground speaker or landscape audio wiring
• CL3/CL2-style in-wall suitability for concealed home theater connections
• UV and weather-resistant outer jacket for long-term outdoor exposure
• 100 feet per spool to cover long runs without splicing

How does CCA (copper-clad aluminum) affect performance and cost?

Copper-clad aluminum uses an aluminum core plated with a thin copper layer to lower material costs while keeping decent electrical conductivity. For typical speaker runs, car audio and many marine applications, CCA provides acceptable signal transfer and considerable savings versus solid copper, though heavy long-distance power delivery benefits from larger copper conductors.

• 180-strand construction improves flexibility and reduces skin-effect losses at audio frequencies
• CCA offers lower price-per-foot compared with pure copper cable
• Ideal for mid-length speaker runs, amps and subwoofer wiring where budget matters
• Not recommended for high-current primary battery cables where pure copper is preferred

What installations and gear is this 12 AWG speaker wire best for?

This wire fits a wide range of audio and low-voltage projects: indoor and outdoor speakers, landscape sound systems, car and marine speakers, and powering amplifiers or powered subwoofers at moderate distances. Its two-conductor layout and larger 12 AWG cross-section make it suitable where lower resistance is needed compared with thinner gauges.

• Home theater speaker runs and multi-room audio drops up to moderate lengths
• Patio, poolside and landscape speaker installations using direct-burial cable
• Car audio and marine speaker wiring where flexibility and corrosion resistance matter
• Power and ground for amplifiers or accessories when matched to amp requirements

Who this is for: Installers, DIY home audio enthusiasts, mobile audio installers and landscapers who want a cost-effective, heavy-gauge speaker cable for runs that need durability outdoors or inside walls. Choose this 12/2 CCA cable when you need a long 100-foot spool, a flexible stranded conductor, and ratings that allow both buried and concealed routing. If you require the absolute lowest resistance for high-current battery feeds or long DC power transmission, consider upgrading to pure copper cable of equal gauge.
