The SA-MS65B marine speakers deliver reliable sound for boat owners who demand durability without sacrificing audio quality. This matched pair handles the harsh marine environment while providing full-range sound from bow to stern.

Each 6.5-inch speaker produces 100 watts RMS with 400-watt peak handling, giving you clean, powerful audio that cuts through wind and engine noise on the water. The 1-inch titanium tweeter delivers crisp highs while the polypropylene cone woofer provides solid bass response down to 55Hz.

Built for marine conditions, these speakers feature waterproof construction with UV-resistant materials that protect against both fresh and salt water exposure. The molded ABS plastic housing withstands sun, spray, and weather while stainless steel terminals resist corrosion. At 4-ohm impedance with 91dB sensitivity, they work efficiently with most marine stereo systems and aftermarket amplifiers.

Perfect for deck mounting on pontoon boats, ski boats, or sailboats where you need consistent sound coverage. The compact 2.5-inch mounting depth fits most marine applications, and the included mounting hardware makes installation straightforward.

Connect directly to your marine head unit's speaker outputs using standard marine-grade speaker wire. The package includes both speakers with all necessary mounting hardware for immediate installation.

Backed by Seismic Audio's one-year warranty and fast shipping, these marine speakers provide professional-grade performance at a price that won't sink your boat budget.

Technical Specifications

Frequently Asked Questions

Will these speakers work with my existing marine stereo?

Yes, the SA-MS65B speakers work with virtually any marine head unit or amplifier. At 4-ohm impedance and 91dB sensitivity, they're efficient enough to run directly from most marine stereos. For maximum performance, consider adding a marine amplifier to drive them at their full 100-watt RMS rating.

What's the difference between waterproof and water-resistant speakers?

These SA-MS65B speakers are fully waterproof, not just water-resistant. They can handle direct water exposure, spray, and submersion without damage. The UV-resistant coating also prevents fading and cracking from sun exposure, making them suitable for both fresh and salt water environments.

How deep do I need to mount these speakers?

The mounting depth is 2.5 inches, which fits most boat installations without interference. You'll need a 5.4-inch cutout diameter for proper fitment. The included mounting hardware accommodates panel thicknesses typically found in marine applications.

Do I need a subwoofer with these marine speakers?

For most recreational boating, these 6.5-inch speakers provide sufficient bass response down to 55Hz. However, if you're looking for deep bass for wakeboarding or prefer heavy bass music, adding a marine subwoofer will enhance the low-end performance significantly.

Can I install these speakers myself?

Yes, installation is straightforward with basic tools. You'll need to cut a 5.4-inch hole, connect positive and negative speaker wires to the stainless steel terminals, and secure with the included mounting hardware. Use marine-grade speaker wire for best corrosion resistance and long-term reliability.
