It is optimized to deliver controlled and robust bass output, even in harsh marine conditions.\n\u003c\/p\u003e\n\n\u003ch3\u003ePerformance and Marine Design\u003c\/h3\u003e\n\u003cp\u003e\n    This Class D monoblock amplifier delivers an RMS power output of 200 watts at 4 ohms or 300 watts at 2 ohms (with some sources indicating up to 350 watts at 2 ohms). Its high-efficiency design minimizes battery drain and heat dissipation. The amplifier chassis is IP67-rated for water and dust resistance (excluding cables) and is spark-proof, making it suitable for installations in engine compartments. Its frequency response ranges from 10 Hz to 500 Hz (+0, -1 dB or +0, -3 dB), with a signal-to-noise ratio exceeding 70 dB (A-weighted, 20 Hz–20 kHz, ref. 1 W).\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegrated Features and Connectivity\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eJL Audio AP300\/1\u003c\/strong\u003e includes an LCD screen for direct access to essential settings, simplifying configuration and audio optimization. It supports JL Audio’s Easy Tune function when paired with a Fusion® system compatible with DSP and the Fusion® Audio app, enabling profile-based setup for optimized sound quality and system protection. Its 10 Hz to 500 Hz bandwidth is specifically tailored for subwoofers, featuring low-pass filters (20–500 Hz, 12 dB\/octave), a variable infrasonic filter (20–50 Hz, 12 dB\/octave), and adjustable bass boost (0–18 dB at 37 Hz). It also includes high-level speaker inputs for easy integration with OEM head units lacking RCA outputs. The system is protected by four-way circuitry against under\/over-voltage, overheating, and short circuits.\n\u003c\/p\u003e\n\n\u003ch3\u003eKey Technical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003eAmplifier class: Class D\u003c\/li\u003e\n    \u003cli\u003eChannels: Monoblock (1 channel)\u003c\/li\u003e\n    \u003cli\u003eRMS power (14.4 V, \u003c1% THD): 200 W x 1 @ 4 ohms, 300 W x 1 @ 2 ohms\u003c\/li\u003e\n    \u003cli\u003eFrequency response: 10 Hz – 500 Hz (+0, -1 dB or +0, -3 dB)\u003c\/li\u003e\n    \u003cli\u003eSignal-to-noise ratio: \u003e70 dB (A-weighted, 20 Hz–20 kHz, ref. 1 W)\u003c\/li\u003e\n    \u003cli\u003eOperating voltage: 9–16 VDC (or 10–16 V)\u003c\/li\u003e\n    \u003cli\u003eProtection rating: IP67 (amplifier chassis, excluding cables)\u003c\/li\u003e\n    \u003cli\u003eOperating temperature range: -20° to 65°C (4° to 149°F)\u003c\/li\u003e\n    \u003cli\u003eInput sensitivity: Low level: 0.2–2 V RMS, High level: 0.8–8 V RMS\u003c\/li\u003e\n    \u003cli\u003eRecommended fuse: 35A (AFS, AGU, or MaxiFuse™ types)\u003c\/li\u003e\n    \u003cli\u003eDimensions (H x W x D): 47 x 265 x 125 mm (1.86\" x 10.43\" x 4.90\")\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":56082917032276,"sku":"010-03428-00","price":331.48,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_ab56e40b-3492-4dc9-9ffb-e225e21845ce.jpg?v=1781188391","url":"https:\/\/skysat.fr\/en-gb\/products\/jl-audio-marine-amplifier-ap300-1-monoblock-ip67","provider":"Skysat","version":"1.0","type":"link"}
