The SA-525M01W marine speakers deliver reliable sound for boats, jet skis, ATVs, and outdoor recreational vehicles that need waterproof audio. This pair of white 5.25-inch speakers handles both fresh and saltwater environments with UV-resistant construction designed for year-round marine use.

Each speaker delivers 50 watts RMS and 100 watts peak power with 90 dB sensitivity, providing clear audio that cuts through wind and engine noise on the water. The 2-way design combines a polypropylene cone woofer with a dedicated tweeter for balanced sound across the 80Hz-20kHz frequency range.

The 4-ohm impedance works with most marine stereos and amplifiers, while the 8-ounce magnet and 1-inch voice coil deliver consistent performance in marine conditions. High-strength molded ABS plastic construction resists corrosion, and the rubber cone surround maintains flexibility in temperature extremes. The 2.2-inch mounting depth fits most standard marine speaker locations.

Install these speakers in boats up to 30 feet, personal watercraft, or outdoor recreational vehicles where you need dependable audio that won't fail when exposed to spray, rain, or saltwater. The white finish matches most marine interiors and won't show water spots like darker colors.

Each speaker includes a mounting cutout template for precise installation. Standard speaker wire connects to your marine stereo or amplifier - no special cables required. Seismic Audio backs these marine speakers with a one-year warranty and fast shipping to get your watercraft audio system running quickly.

Technical Specifications

Frequently Asked Questions

Will these speakers work with my boat stereo?

Yes, these 4-ohm marine speakers work with virtually all boat stereos and marine amplifiers. Connect them using standard marine-grade speaker wire - the same type you'd use for any boat audio installation. Most boat stereos provide adequate power to drive these speakers effectively.

How big of a boat can these speakers handle?

These speakers work well for boats up to 30 feet and personal watercraft like jet skis or wave runners. For larger vessels or boats with significant engine noise, consider adding a marine amplifier to boost the power and ensure the audio remains clear over ambient noise.

Are these truly waterproof for saltwater use?

Yes, these speakers feature waterproof construction with UV-resistant materials designed specifically for marine environments. The ABS plastic housing and rubber surrounds resist corrosion from both fresh and saltwater exposure, making them suitable for ocean boating and freshwater lakes alike.

What's the mounting depth and will they fit my existing cutouts?

These speakers require 2.2 inches of mounting depth behind the installation surface and have a 4.8-inch mounting diameter. They'll fit most standard 5.25-inch marine speaker cutouts. Each speaker includes a mounting template to ensure precise cutting if you're installing in a new location.

Do I need an amplifier with these speakers?

While not required, an amplifier will significantly improve performance, especially on larger boats or in noisy environments. Most marine stereos provide 15-25 watts RMS per channel, which will drive these speakers but won't reach their full 50-watt RMS potential for maximum volume and clarity.
