Installation Notes

The NXL-6M/BK fits most standard 6.5-inch marine speaker openings and is designed for boats and outdoor vehicles. For maximum durability, use marine-grade wiring, waterproof connectors, and stainless-steel mounting hardware. The integrated RGB lighting requires the optional DS18 LC-RGB controller for full color and lighting effect customization.

Pro Audio Center Tip

Black marine speakers are a popular choice for boats, Jeeps, and powersports vehicles with darker interiors or trim because they create a clean, factory-inspired appearance while hiding dirt and wear better than lighter-colored speaker grilles. For the best long-term performance, pair them with marine-grade wiring and sealed electrical connections.
