Marine audio upgrade

The Infinity 622MW 6.5" 2-Way Marine Coaxial Speakers are built for boat owners who need reliable sound in wet, sun-exposed environments. Each speaker handles 75W RMS and 225W peak power with a 92dB sensitivity rating at 2.83V/1m. The frequency response spans 50Hz to 20KHz at a 4-ohm impedance. A corrosion-proof basket and water- and UV-resistant construction protect the drivers from salt spray and sunlight.

Mounting hardware included

Stainless-steel mounting hardware is supplied in the box, so no separate bracket purchase is required. The integral grille shields the cone and tweeter from impact and debris while maintaining a clean appearance. These items are the only accessories bundled; no amplifier, wiring kit or signal processor is included. The Class D amplifier specification refers to a compatible amplifier type, not a built-in module.

Check your helm space

Verify that a 6.5" cut-out fits your console or cabin panel before ordering. Confirm your amplifier or head unit can deliver up to 75W RMS per channel into a 4-ohm load. Ensure the mounting depth behind the panel accommodates the speaker basket and that the 4.49kg total weight for the pair is acceptable for your installation location. Buyers needing a different driver size or higher power handling should look elsewhere.

Questions about this item

Will the stainless-steel mounting hardware ever need replacement?

The included stainless-steel mounting hardware resists corrosion in marine environments, so it does not require routine replacement under normal use.

What limits output first during long listening sessions — the 75W RMS thermal rating or the 4-ohm impedance?

The 75W RMS rating is the thermal limit; sustained power above this level will cause the voice coils to overheat before impedance becomes a factor.

How much heat do these 92dB sensitivity speakers produce when run all day at moderate volume?

At typical listening levels the 92dB sensitivity keeps amplifier current low, so heat buildup in the voice coils and corrosion-proof basket remains minimal.
