Description
GME GS620W 140W White Marine Flush Mount Speakers Pair IP54 188mm ASTM Salt Spray and UV Compliant 4 Ohm
The GME GS620W is a pair of 140W IP54 flush mount marine speakers in white, 188mm in diameter. GME's higher-power, larger-diameter marine flush mount option larger than the GS520W (163mm) and rated at 140W per speaker for greater acoustic output suited to open-air decks, cockpits, and vessels requiring more volume and bass response. ASTM B117-03 salt spray and ASTM G154 UV compliance confirm suitability for saltwater and sun-exposed marine environments. Supplied as a pair.
Product overview
The GS620W installs flush to the panel surface for a clean, built-in appearance on helm panels, cabin bulkheads, and cockpit surfaces. The 188mm diameter provides greater cone area than the 163mm GS520W, producing improved bass response and higher acoustic output suited to vessels and applications where more volume is needed, particularly in open-air or noisy underway conditions.
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 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. Both standards are relevant for marine-grade audio equipment installed in exposed locations.
At 4 Ohm impedance, the GS620W suits standard marine amplifiers and head units. The speakers are rated at 140W each for full-power performance, particularly in open-air or noisy vessel environments, a dedicated marine amplifier rated at approximately 100 to 140W RMS per channel at 4 Ohm is recommended. A head unit operating at lower power will drive the GS620W but will not reach the speakers' rated output capability. Confirm the exact panel cutout diameter with GME before cutting, as the required cutout is smaller than the 188mm outer speaker diameter.

Frequently asked questions
What panel cutout is required for the GS620W? The GS620W has an outer diameter of 188mm. The actual panel cutout will be smaller than this typically around 162 to 170mm for a speaker of this size, but the exact cutout diameter should be confirmed before cutting the panel. Contact us to confirm the required cutout dimension.
What power amplifier is recommended for 140W speakers? For the GS620W to operate at its rated capability, use a marine amplifier rated at approximately 100 to 140W RMS per channel at 4 Ohm. A head unit running at lower power will drive the GS620W but will not reach the speakers' full rated output a dedicated marine amplifier is recommended for open-air and noisy vessel environments.
What do the ASTM B117-03 and ASTM G154 standards mean? ASTM B117-03 is the salt spray (fog) corrosion test standard, confirming the speaker materials and coatings withstand prolonged exposure to salty marine air and spray. ASTM G154 is the UV exposure test, confirming resistance to UV degradation from direct sunlight. Both confirm suitability for exposed marine audio installations.
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 typical at the helm and cockpit. IP54 is not a submersion rating.
How does the GS620W compare to the GS520W? The GS620W is 188mm in diameter and rated at 140W per speaker. The GS520W is 163mm in diameter and rated at a lower output. The GS620W is the larger, higher-power option suited to open-air decks, larger cockpits, and applications requiring greater volume and bass response.
