JL Audio Parallel Conductor Speaker Cable, For Marine Speaker Systems, Tinned Copper Conductors, White PVC Jacket

Overview

The JL Audio White Parallel Conductor Speaker Cable is a two-conductor marine speaker wire offered in 12 AWG or 16 AWG, with lengths from 25 ft (7.6 m) up to 500 ft (152.4 m). It uses tinned oxygen-free copper conductors inside a soft white PVC jacket, so the cable stays easy to route while helping slow corrosion in damp compartments and salty air.

This is the cable you run between a marine amplifier or head unit and your speakers. The parallel conductor layout keeps the two runs together and makes it easier to maintain correct speaker polarity when you are pulling wire through chases, under gunwales, or behind helm panels.

Key features

• Parallel two-conductor layout helps keep speaker polarity consistent during installation and troubleshooting
• Tinned oxygen-free copper conductors help reduce corrosion issues common in saltwater environments
• Soft, flexible white PVC jacket is easier to pull through conduits, lockers, and tight rigging runs
• True 12 AWG and true 16 AWG options to match different run lengths and system power demands
• Available as 25 ft cut lengths for targeted jobs and bulk spools for full boat rewires

Variants

This cable is available in multiple gauge and length combinations for everything from a single speaker run to a complete multi-zone install.

The variants differ by American Wire Gauge (AWG) and total length. The white PVC jacket, parallel-conductor format, and tinned copper construction remain consistent across the range.

• 010-13424-00: 16 AWG, 25 ft (7.6 m). A practical length for a focused install such as a helm-to-cabin run or a single pair of speakers.
• 010-13425-00: 16 AWG, 500 ft (152.4 m). Bulk spool suited to multi-speaker systems where you are pulling many shorter runs throughout the boat.
• 010-13449-00: 12 AWG, 25 ft (7.6 m). Heavier gauge in a manageable length when you are keeping resistance low on a short, higher-demand run.
• 010-13450-00: 12 AWG, 380 ft (115.8 m). Bulk spool for longer pulls, larger boats, and higher-power audio zones that benefit from thicker conductors.

Installation and setup

Route speaker cable away from sharp edges and moving gear, then secure it so it cannot chafe under vibration. In wet lockers and bilge-adjacent runs, sealed terminations and adhesive-lined heat shrink help keep connections stable over time.

When running near high-current DC wiring, keep separation where possible to reduce the chance of noise pickup. Label both ends during the pull so final speaker hookup at the amplifier and at each speaker stays straightforward.

Compatibility and fit

This is standard two-conductor speaker cable for marine audio systems, so it pairs with typical speaker terminals, marine amplifiers, and head units. Confirm your speaker and amplifier terminals can accept the selected gauge, especially with 12 AWG in tighter terminal blocks.

On-board use notes

This cable is a good match for boaters who want clean, consistent wiring for cockpit, cabin, or tower speaker runs and who need a jacket that stays flexible during routing. Bulk spools make sense for new builds, refits, or multi-zone audio layouts where you want one cable type throughout the boat.
