Gravity MG680-LW 6.5" 2-Way Marine Speakers with Blue LEDs

The Gravity MG680-LW is a pair of 6.5-inch, 2-way marine speakers designed for wired audio systems in boats, personal watercraft, and off-road vehicles. It provides a replacement option for worn or basic factory speakers where moisture resistance and a compact mounting profile are important. The white finish is suited to marine interiors and exterior panels.

Each pair is specified with a 350-watt peak power rating, 4-ohm impedance, 88 dB sensitivity, and an 80 Hz to 20 kHz frequency response. This combination is intended for use with a compatible marine stereo or external amplifier that supports 4-ohm speakers. The 2-way design combines a 6.5-inch woofer with a 1-inch tweeter for full-range playback.

Built-in blue LED illumination adds accent lighting around the speakers for nighttime boating or powersports use. The LEDs are integrated into the speaker assembly, so they should be connected as part of a properly planned installation. This makes the pair a practical choice for systems that combine sound reproduction with visible marine-style lighting.

The MG680-LW uses a water-resistant, weather-resistant design with UV protection for outdoor installations exposed to splashes and changing conditions. Its anti-resonant stamped basket is designed to support the speaker assembly, while spade terminals simplify connection to conventional speaker wiring. The listed 60 mm mounting depth supports installations where rear-panel clearance is limited.

These speakers can be used as a pair in a new marine audio installation or as replacements in compatible 6.5-inch OEM-style locations. They are intended to connect to an external audio source or amplifier; they do not function as a standalone Bluetooth speaker system. Confirm cutout size, mounting depth, wiring access, and available clearance before installation.

Key Features

• 6.5-Inch 2-Way Design: Combines a woofer and tweeter in each speaker.
• 350-Watt Peak Rating: Provides the listed peak handling for the pair.
• 4-Ohm Impedance: Works with compatible marine stereo or amplifier channels.
• Blue LED Lighting: Adds integrated blue accent illumination around each speaker.
• Weather-Resistant Construction: Supports use in marine and outdoor vehicle environments.
• 60 mm Mounting Depth: Helps fit installations with limited rear clearance.

Design & Installation

The MG680-LW has a white, low-profile marine-speaker design with UV protection, water-resistant construction, and an anti-resonant stamped basket. It uses a 6.5-inch woofer, 1-inch tweeter, and built-in blue LED lighting. The speakers are sold as a pair for stereo installation.

Mount the speakers on a flat panel with at least 60 mm of depth behind the mounting surface, allowing additional clearance for wiring. Connect the speaker leads to a compatible 4-ohm stereo or amplifier using the spade terminals, observing polarity. Verify the vehicle's cutout size and plan separate wiring as needed for the integrated LED lighting before drilling or fastening the speakers.
