Engineered to deliver robust and efficient power in extremely tight spaces, this amplifier pushes 50 watts RMS to four channels at 4 ohms, or up to 75 watts RMS at 2 ohms, making it an excellent choice for powering a complete set of coaxial or component speakers. Thanks to its highly efficient Class-D topology, the KS-DR2004D provides crystal-clear, high-output audio without placing excessive strain on your vehicle's charging system, all while maintaining a remarkably small physical footprint that easily tucks away behind a dashboard, under a seat, or inside a motorcycle fairing.\u003cbr\u003e\u003cbr\u003e\n\nBuilt for the great outdoors, the KS-DR2004D features a rugged, weather-resistant design that makes it perfect for marine and powersports applications. The internal circuitry is protected by a conformal-coated printed circuit board (PCB) that resists moisture, salt, and dampness, while the wiring utilizes sealed pigtail connections for maximum reliability in harsh environments. To ensure your speakers sound their absolute best, the amplifier includes built-in variable High-Pass and Low-Pass filters, allowing you to precisely tune your system's frequencies for optimal clarity and performance. Whether you're hitting the trails, cruising the waves, or commuting on the highway, this JVC amplifier delivers dependable, high-fidelity sound.\u003cbr\u003e\u003cbr\u003e\n\n\u003cb\u003eKey Features\u003c\/b\u003e\u003cbr\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eCompact Class-D Technology\u003c\/b\u003e: Highly efficient digital amplifier design delivers big power from an ultra-small chassis that fits almost anywhere.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eMarine \u0026amp; Powersports Ready\u003c\/b\u003e: Features a conformal-coated PCB to protect vital circuitry from moisture, salt spray, and extreme environments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eSealed Pigtail Wiring\u003c\/b\u003e: Utilizes hardwired pigtail connections for the power, ground, and speaker leads to prevent water intrusion at the terminals.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eBridgeable Operation\u003c\/b\u003e: Can be bridged to provide a powerful 150 watts RMS to two channels for subwoofers or high-power component sets.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eBuilt-In Crossovers\u003c\/b\u003e: Variable High-Pass and Low-Pass filters let you fine-tune your audio signal for maximum speaker efficiency and sound quality.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eComprehensive Protection\u003c\/b\u003e: Includes built-in circuitry to protect against short circuits, thermal overload, and voltage fluctuations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cb\u003eSpecifications\u003c\/b\u003e\u003cbr\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cb\u003eAmplifier Class\u003c\/b\u003e: Class-D Digital\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eChannel Configuration\u003c\/b\u003e: 4 \/ 3 \/ 2 Channels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eRMS Power @ 4 Ohms\u003c\/b\u003e: 50 Watts x 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eRMS Power @ 2 Ohms\u003c\/b\u003e: 75 Watts x 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eBridged RMS Power @ 4 Ohms\u003c\/b\u003e: 150 Watts x 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eFrequency Response\u003c\/b\u003e: 10 Hz – 20 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eCrossovers\u003c\/b\u003e: Variable HPF \/ LPF (50Hz - 200Hz)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eSignal-to-Noise Ratio\u003c\/b\u003e: \u0026gt;89 dB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cb\u003eApplication\u003c\/b\u003e: Car, Marine, Motorcycle, and ATV\/UTV\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JVC","offers":[{"title":"Default Title","offer_id":67677828284565,"sku":"KS-DR2004D","price":299.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0482\/2174\/9397\/files\/KSDR2004D_2.jpg?v=1791622999","url":"https:\/\/lifeafterbass.shop\/products\/jvc-ks-dr2004d-400w-max-4-channel-class-d-compact-marine-powersports-amplifier","provider":"LifeAfterBass","version":"1.0","type":"link"}
