The GME GS500 is a pair of 110W IP54 flush mount marine speakers in white, 163mm in diameter and 4 Ohm impedance. Suited to standard round speaker cutouts on helm panels, cabin bulkheads, and cockpit surfaces. ASTM B117-03 salt spray and ASTM G154 UV compliance confirm suitability for saltwater and sun-exposed marine environments. Optional S5BG black grilles available separately for vessels with dark colour schemes.
The GS500 installs flush to the panel surface for a clean, professional built-in appearance the speaker basket sits within the panel thickness and the grille finishes flush to the surface. IP54 covers dust and water spray from any direction including splash, rain, wave spray, and wash-down conditions typical at the helm and cockpit. ASTM B117-03 salt spray compliance confirms corrosion resistance in saltwater environments. ASTM G154 UV compliance confirms material and finish resistance to direct sunlight.
At 163mm outer diameter, the GS500 fits most standard round marine panel cutout templates. The actual panel cutout required will be smaller than 163mm confirm the exact cutout dimension before cutting the panel. At 4 Ohm impedance and 110W per speaker, a dedicated marine amplifier rated at 75 to 110W RMS per channel at 4 Ohm is recommended for full-power performance. A lower-power head unit will drive the GS500 functionally, but a dedicated amplifier allows the speakers to perform at their rated capability. Significant underpowering can cause distortion at high volume.
The optional S5BG black grilles replace the included white grilles for a contrasting or all-dark appearance suited to vessels with dark colour schemes. The GS500 is a larger, higher-power flush mount alternative to the GS320W box speaker (109 x 96mm, 60W per speaker), suited to applications where a round panel cutout is available and more output is required.
2x110W flush mount speakers supplied as a pair: 110W per speaker for powerful marine audio at the helm and cockpit.
IP54 water ingress protection: Protected against dust and water spray from any direction splash, rain, wave spray, and wash-down conditions.

What is a flush mount speaker and how is it installed? A flush mount speaker installs in a round hole cut into a panel the basket sits inside the panel thickness and the grille sits flush with the surface for a clean, built-in appearance. Installation requires cutting a round hole to the correct cutout diameter (smaller than the 163mm outer diameter) and sufficient depth for the speaker basket. Contact us to confirm the exact cutout dimension before cutting.
What does the 163mm diameter mean for installation? 163mm is the outer diameter of the speaker. The actual panel cutout will be smaller confirm the exact cutout dimension before cutting the panel. The 163mm outer diameter suits most standard round marine panel cutout templates.
What amplifier power 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 GS500 functionally, but a dedicated marine amplifier provides full performance at the speakers' rated 110W capability. Significant underpowering can cause distortion at high volume.
Are the optional S5BG black grilles interchangeable with the white grilles? The S5BG is listed as optional black grilles for the GS500, designed to replace the included white grilles for a contrasting or all-dark appearance. Contact us to confirm whether the S5BG is a direct swap for the standard white grilles.
How does the GS500 compare to the GS320W box speakers? The GS320W is a compact marine box speaker at 109 x 96mm with 60W per speaker, suited to tighter spaces where a round panel cutout is not available. The GS500 is a larger flush mount speaker at 163mm with 110W per speaker, providing more power and a clean built-in installation. Select based on available panel space and preferred installation method.
