Description
GME GS520W 110W White Marine Flush Mount Speakers Pair IP54 163mm ASTM Salt Spray and UV Compliant 4 Ohm
The GME GS520W is a pair of 110W IP54 flush mount marine speakers in white, 163mm in diameter and 4 Ohm impedance. Compatible with standard marine amplifiers and head units and sized for standard round panel cutouts on vessels. ASTM B117-03 salt spray and ASTM G154 UV compliance confirm suitability for saltwater and sun-exposed marine environments. Flush mount design provides a clean, built-in finish on helm panels, cabin bulkheads, and cockpit surfaces. Supplied as a pair.
Product overview
The GS520W installs flush to the panel surface for a professional built-in appearance. IP54 covers dust and water spray from any direction splash, rain, wave spray, and wash-down conditions typical at the helm and cockpit. ASTM B117-03 salt spray testing confirms resistance to corrosion from saltwater air and spray. ASTM G154 UV exposure testing confirms resistance to material and finish degradation from direct sunlight.
The 163mm diameter fits standard round marine panel cutouts. The actual panel cutout required will be smaller than the 163mm outer speaker diameter confirm the exact cutout dimension before cutting the panel. At 4 Ohm impedance, the GS520W is compatible with standard marine amplifiers and head units. For best performance, use an amplifier rated at 75 to 110W RMS per channel at 4 Ohm. A head unit operating at lower power will drive the GS520W functionally but will not reach the speakers' rated 110W output capability.
For a larger, higher-power option, the GS620W (188mm, 140W per speaker) is the larger GME marine flush mount alternative.

Frequently asked questions
How are flush mount speakers installed and what panel cutout is required? Flush mount speakers install in a round hole cut into the panel the speaker basket sits within the panel thickness and the grille finishes flush with the surface. The panel cutout will be smaller than the 163mm outer speaker diameter. Contact us to confirm the exact cutout dimension required before cutting.
What power amplifier is recommended for 110W speakers? For best performance, use an amplifier rated at 75 to 110W RMS per channel at 4 Ohm. A lower-power head unit will drive the GS520W functionally, but a dedicated marine amplifier provides fuller performance at the speakers' rated capability.
What do the ASTM B117-03 and ASTM G154 standards mean? ASTM B117-03 is the salt spray (fog) corrosion resistance test confirming the speaker materials and coatings withstand prolonged exposure to saltwater air and spray. ASTM G154 is the UV exposure test confirming resistance to material and finish degradation from direct sunlight. Both are key reliability indicators for marine equipment installed in exposed locations.
What does IP54 protect against? IP54 means the speakers are protected against dust ingress and water spray from any direction, covering splash, rain, wave spray, and wash-down conditions at the helm and cockpit. IP54 is not a submersion rating.
How does the GS520W compare to the GS620W? The GS520W is 163mm in diameter and rated at 110W per speaker. The GS620W is 188mm in diameter and rated at 140W per speaker. The GS620W is the larger, higher-power option suited to open decks, larger cockpits, and applications requiring greater volume and bass response.
