{"title":"8\" Marine Subwoofers","description":"\u003cp\u003eAn \u003cstrong\u003e8\" marine subwoofer\u003c\/strong\u003e is the best compromise between bass extension and installation flexibility for space-constrained boat builds. Where a 10\" or 12\" sub requires a dedicated locker or a significant custom enclosure, an 8\" can go under a seat, in a compact fiberglass enclosure on a swim platform, or in a shallow under-gunwale mount.\u003c\/p\u003e\n\n\u003ch3\u003eWhat to Expect from an 8\" Marine Sub\u003c\/h3\u003e\n\u003cp\u003eRealistically: usable bass extension down to around 45–55 Hz, noticeably more impact than coaxials alone, and the ability to fill in the low end that no coaxial speaker can reproduce at volume. An 8\" won't move your organs the way a 12\" will, but that's not the point — the point is meaningful low-end contribution from a package that actually fits in your boat.\u003c\/p\u003e\n\n\u003ch3\u003eEnclosure Options\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSealed (ported)\u003c\/strong\u003e — tighter, more accurate bass; smaller enclosure requirement. For an 8\" sub, a 0.4–0.6 cubic foot sealed box is typical.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorted (vented)\u003c\/strong\u003e — louder at the tuning frequency, slightly softer attack; requires a larger enclosure (0.75–1.0 cubic foot typically). More efficient per watt below the tuning point.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree-air\u003c\/strong\u003e — some 8\" marine subs are rated for free-air installation (mounted in a panel with no enclosure behind them, such as a transom). Convenient but compromised bass compared to an enclosed install.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAmplifier Pairing\u003c\/h3\u003e\n\u003cp\u003eAn 8\" marine sub typically handles 150–300W RMS. A small mono marine amplifier (Kicker KXMA800.1 or JL Audio MX500\/1) is the correct pairing. Run it bridged from a 2-channel amp if you don't want a separate mono unit — just watch your impedance load.\u003c\/p\u003e\n\n\u003cp\u003eAuthorized dealer for Kicker, JL Audio, DS18, Infinity, and Boss Marine.
