It is a passive 4-ohm subwoofer, so it requires a compatible external amplifier. The gray finish coordinates with marine installations while providing dedicated bass support for open-air listening.\u003c\/p\u003e\u003cp\u003eBuilt for marine environments, this Stage Marine subwoofer uses an IPX5-rated design with marine-grade materials and components. Its polypropylene cone, rubber surround, one-piece polymer basket, stainless-steel mounting hardware, and UV-resistant grille are intended for exposure to spray, sunlight, and washdowns. These construction details make it suited to boats where conventional car-audio components may not be appropriate.\u003c\/p\u003e\u003cp\u003eThe driver handles 200 watts RMS and 600 watts peak, with a 30 Hz to 250 Hz frequency response. JBL rates sensitivity at 88 dB measured at 2.83V. This combination is intended to reinforce bass frequencies that can be harder to hear in an open-air marine setting.\u003c\/p\u003e\u003cp\u003eInstallation flexibility is a central part of the design. The JBLMARSUBST10GRYAM can be used in an infinite-baffle\/free-air location, a sealed enclosure, or a vented enclosure. That gives installers options based on available boat space and the desired enclosure approach.\u003c\/p\u003e\u003cp\u003eUse this subwoofer as the low-frequency section of a marine system with full-range marine speakers and an amplifier matched for a 4-ohm load. Its 10-inch format offers a practical size for many helm, cockpit, cabin, and storage-compartment installations. JBL includes the primary mounting and connection accessories needed to prepare the driver for installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Inch Marine Subwoofer:\u003c\/strong\u003e Adds dedicated bass reproduction to a compatible boat audio system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e200W RMS Power Handling:\u003c\/strong\u003e Supports amplifier matching up to its continuous power rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIPX5 Marine Rating:\u003c\/strong\u003e Helps suit the subwoofer to wet outdoor marine environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolypropylene Cone:\u003c\/strong\u003e Provides a marine-ready cone material for bass reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Enclosure Use:\u003c\/strong\u003e Supports free-air, sealed, or vented installation approaches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGray UV-Resistant Grille:\u003c\/strong\u003e Provides a finished appearance with protection from sunlight exposure.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe JBLMARSUBST10GRYAM combines a polypropylene cone and rubber surround with a one-piece polymer basket.
