JL Audio M3-770X-C-Gw 7.7" 70W RMS Marine Coaxial Speakers, White Classic Grilles, Pair (010-03065-00)

Upgrade the sound and appearance of your boat with the JL Audio M3-770X-C-Gw 7.7" M3 Series marine coaxial speakers. With white classic grilles, these speakers are built for clear, full-range listening in cockpits, cabins and exposed marine locations. Their marine-grade woofer and tweeter components are engineered to withstand moisture, UV exposure and salt-laden environments.

Each speaker handles 70 watts RMS and uses a dedicated tweeter for detailed vocals and high frequencies, while the woofer supplies the midbass needed to make music engaging on the water. This is the non-illuminated version, with no RGB lighting circuitry or additional lighting wiring required.
