Pros & Cons
👍 Pros
- UV protection and water resistance built for prolonged marine exposure
- 350 watts peak power provides strong output for open-air listening
- 88 dB sensitivity means they produce reasonable volume without a high-powered amp
- Anti-resonant stamped basket reduces unwanted vibration and distortion
- White finish blends with standard boat and dock aesthetics
👎 Cons
- 60mm mounting depth may not fit thinner boat panels without modification
- Peak power rating of 350 watts does not reflect continuous RMS handling, which is not specified
- Spade terminals may require adapters for some marine stereo head units
- 88 dB sensitivity is moderate and may need amplifier support in noisy open-water conditions
Frequently Asked Questions
Are these speakers waterproof?
They are water-resistant and UV-protected for marine environments, but they are not rated as fully waterproof — they should not be submerged.
What mounting depth is required for installation?
The MG680-LW requires a mounting depth of 60mm, so verify that your boat's panels or enclosures can accommodate that measurement before purchasing.
Do these speakers come in pairs?
Product listings should be checked for quantity, as marine speakers are sometimes sold individually and sometimes as a pair.
What type of terminals do these speakers use?
They use spade speaker terminals, which are common in marine and car audio installations and compatible with most aftermarket wiring harnesses.
What amplifier power is recommended for these speakers?
With 350 watts peak power and 4-ohm impedance, a moderate marine amplifier in the 50–100 watt RMS per channel range would be a suitable match for clean, undistorted sound.
