Description
Professional 6-conductor multifunction cable engineered specifically for LED-illuminated marine speakers, combining audio and lighting power in a single marine-grade cable.
Product Overview
The JL Audio XM-WHTMFC 6-conductor multifunction cable delivers convenient integrated wiring for LED-illuminated marine speakers and subwoofers. Featuring two 16 AWG OFC copper speaker leads plus four 20 AWG OFC copper illumination leads in a single marine-grade white PVC jacket, this innovative cable eliminates the need for separate speaker wire and LED power wire runs—simplifying installations, reducing bulkhead penetrations, and maintaining clean professional appearance in marine audio systems. The 250-foot (76.2-metre) professional spool accommodates complete vessel LED speaker system installations, multi-zone projects, or professional marine audio operations requiring substantial multifunction cable inventory.
Ideal for use with JL Audio speakers and subwoofers featuring RGB LED illumination—including M3, M6, and M7 marine series with lighting capability—the stannum-plated (tin-plated) OFC copper construction provides exceptional corrosion resistance critical for Australian coastal boating environments. Fine-strand construction ensures optimum flexibility despite the 6-conductor bundle, enabling routing through tight bilge spaces, overhead panels, and crowded equipment bays. The marine-grade white PVC jacket matches common boat interior aesthetics while protecting all conductors from salt spray, moisture, and UV exposure. Professional marine audio installers appreciate the time savings: one cable pull handles both audio signal and LED power instead of coordinating separate wire runs through bulkheads and conduit.

Features & Benefits
Integrated Audio and LED Power in Single Cable
The 6-conductor design combines speaker audio (two 16 AWG conductors) and LED illumination power (four 20 AWG conductors) in one cable, eliminating the need for separate wire runs. Install LED-equipped marine speakers with a single cable pull through bulkheads, conduit, or overhead panels instead of coordinating two separate cables. Reduces installation time, minimizes bulkhead penetrations vulnerable to water ingress, and simplifies cable management in crowded equipment bays. Essential for professional installers servicing multiple LED speaker installations where efficiency directly impacts project profitability.
True 16 AWG OFC Copper for Audio Signal
The two speaker conductors feature genuine 16 AWG specification with pure oxygen-free copper (OFC) construction—not undersized or copper-clad aluminum found in budget cables. The 16 AWG gauge ensures minimal resistance signal transmission for clean audio reproduction across typical marine speaker runs up to 50 feet. The OFC copper provides superior conductivity compared to CCA (copper-clad aluminum) alternatives, maintaining bass impact, midrange clarity, and high-frequency extension that inferior conductors compromise.
Four 20 AWG Conductors for RGB LED Control
The four illumination leads provide complete RGB LED control: common positive/negative plus three colour channels (red, green, blue) for full-spectrum colour mixing and effects control. The 20 AWG gauge handles typical LED current requirements without voltage drop that causes dimming or colour inconsistency across multiple speaker zones. Compatible with JL Audio's RGB LED lighting systems in M-series marine speakers, enabling synchronized colour effects across cabin, cockpit, and tower installations from centralized LED controllers.
Stannum-Plated Copper for Marine Corrosion Resistance
Stannum plating (tin plating) on all six conductors prevents the green oxidation (verdigris) that destroys standard copper wire in marine environments. The tin coating creates a protective barrier against salt spray, bilge moisture, and corrosive conditions encountered in Australian coastal boating. Unlike bare copper that corrodes within months of saltwater exposure, stannum-plated copper maintains conductivity and connection integrity for years—critical for LED circuits where resistance increase from corrosion causes lighting failure or intermittent operation.
Fine-Strand Construction for Optimum Flexibility
Despite containing six separate conductors (totaling more copper than single 16 AWG speaker wire), the fine-strand construction maintains flexibility for routing through tight spaces. Many multifunction cables become stiff and resist bending due to multiple heavy-gauge conductors bundled together. The XM-WHTMFC's fine-strand design enables professional wire routing around corners, through bulkhead penetrations, and along existing cable bundles without kinking or creating installation challenges. The flexibility also reduces strain on speaker terminals and LED connections.
Marine-Grade White PVC Jacket
The outer white PVC jacket provides comprehensive protection for all six conductors while matching common marine interior aesthetics—white gelcoat, headliners, and cabin panels typical in boats. The marine-grade PVC resists UV degradation, salt spray, moisture ingress, and temperature extremes encountered in Australian boating from tropical Queensland to Southern Ocean conditions. The white colour maintains clean professional appearance in visible installations and simplifies wire identification against darker bilge areas or equipment bay backgrounds.
250-Foot Professional Spool
The 250-foot (76.2-metre) spool accommodates professional installations requiring multiple LED speaker runs: complete 4-6 speaker vessel installations (40-50 feet per speaker run including routing), multi-zone distributed LED audio systems, or marina service operations maintaining inventory for multiple boats. Professional installers appreciate the bulk format for job-site efficiency—one spool handles typical LED speaker projects without mid-installation cable shortages. The length balances project capacity with practical spool handling versus unwieldy 500-foot formats.
Simplified Installation Reduces Labor Costs
Every LED speaker installation requiring this multifunction cable represents 40-50% labour time savings versus running separate speaker wire and LED power wire. Single cable pulls through bulkheads, overhead panels, and conduit eliminate coordination challenges between two wire runs. Reduced bulkhead penetrations mean fewer holes to seal against water ingress. Professional installers translate time savings directly to improved project profitability or competitive pricing advantage.

Some high-power LED applications may require separate heavier-gauge LED power runs rather than the integrated 20 AWG conductors.
Frequently Asked Questions
What are the four 20 AWG conductors used for in RGB LED systems?
RGB LED systems require four connections: one common (typically positive or negative depending on LED type) and three individual colour channels (red, green, blue). The LED controller sends different current levels to each colour channel, mixing colours for full-spectrum effects. The four 20 AWG conductors provide these four connections between LED controller and speaker LED elements.
Can I use this cable for speakers without LED lighting?
Yes, but it's economically inefficient. You'd only use the two 16 AWG speaker conductors, leaving four 20 AWG illumination conductors unused. For non-LED speakers, standard 16 AWG 2-conductor speaker wire costs significantly less. This multifunction cable's value proposition is specifically for LED-equipped speakers where integrated wiring simplifies installation.
Is 250 feet enough for a complete boat LED speaker system?
Calculate your specific requirements: typical installation uses 40-60 feet per speaker location (amplifier/controller to speaker including routing). A 6-speaker LED system requires approximately 240-360 feet total. The 250-foot spool handles 4-5 speaker locations with normal routing, or 3-4 speakers with complex routing. For larger systems, order multiple spools or measure carefully to avoid shortages.
What does "stannum-plated" mean?
Stannum is the Latin name for tin (chemical symbol Sn). Stannum-plated means tin-plated—a thin tin coating applied over copper conductors. This prevents copper corrosion (green oxidation) in marine environments, maintaining conductivity and connection integrity for years in saltwater conditions. It's the same corrosion protection as "tinned copper" but using the technical Latin terminology.
Can I separate the conductors to route audio and LED power differently?
Not recommended. The cable is designed as an integrated bundle—separating conductors removes the jacket protection and exposes individual conductors to environmental damage. If you need different routing for audio versus LED power, use separate standard speaker wire and LED power wire rather than this multifunction cable. The integrated design's value is specifically for unified routing.
