Having toured JL Audio myself, I can tell you these guys take two things very seriously — great sound and life on the water. These M3-770X-S-Gm-i 7.7″ marine speakers combine durable, marine-ready design, outstanding audio performance, and the cool look of subtle blue lighting. Supplied with plenty of power, these oversized speakers can overcome that wicked combination of wind, water, and engine noise. Plus, the built-in LED lighting brightens up any nighttime cruise.
