It uses JL Audio’s NexD™ Class D switching technology to deliver 500 watts RMS distributed across four channels. Its design is optimized for high-fidelity audio performance without overloading the vessel’s charging systems.\n\u003c\/p\u003e\n\n\u003ch3\u003eAudio performance and marine robustness\u003c\/h3\u003e\n\u003cp\u003e\n    This amplifier delivers 70 watts RMS x 4 at 4 ohms, 125 watts RMS x 4 at 2 ohms, or 250 watts RMS x 2 in bridged mode at 4 ohms. Its frequency response ranges from 20 Hz to 20 kHz (+0, -1 dB) with a signal-to-noise ratio greater than 88 dB (A-weighted). Total harmonic distortion (THD+N) is less than 1% at 2 ohms per channel. To accommodate different speaker configurations, it features adjustable high-pass and low-pass filters (35–300 Hz, 12 dB\/octave).\n\u003c\/p\u003e\n\u003cp\u003e\n    Built for durability in marine environments, the \u003cstrong\u003eMX500\/4\u003c\/strong\u003e amplifier features a compact die-cast aluminum chassis resistant to corrosion, with a powder-coated finish. It is rated IPX7 for water resistance, supporting immersion up to 1 meter for 30 minutes provided the control panel cover is properly installed. Balanced differential inputs help minimize noise induced by cables, a key advantage in marine installations. An advanced protection system (Advanced Rollback Protection System) prevents thermal shutdown under extreme conditions.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegration and installation\u003c\/h3\u003e\n\u003cp\u003e\n    The amplifier is compatible with 12-volt negative-ground electrical systems. It accepts both low-level (RCA, 250 mV – 4 V RMS) and high-level (750 mV – 15 V RMS) input signals, enabling integration with various audio sources. For power, a 4 AWG gauge cable is recommended for both positive and negative leads. A 50A external fuse (AFS, AGU, or MaxiFuse™) must be installed within 45 cm of the battery’s positive terminal. Its compact dimensions (237 mm L x 45 mm H x 115 mm D) facilitate installation in tight spaces. The unit ships with four stainless-steel mounting screws and a user manual.\n\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":56076442141012,"sku":"010-03106-00","price":364.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_c4d44e7d-a6a8-4194-921f-a34341263f1f.jpg?v=1781127733","url":"https:\/\/skysat.fr\/en-us\/products\/jl-audio-marine-amplifier-mx500-4-500w-ipx7","provider":"Skysat","version":"1.0","type":"link"}
