The \u003cstrong\u003eDiamond Audio MICRO84U\u003c\/strong\u003e is a \u003cstrong\u003e4-channel full range Class D amplifier\u003c\/strong\u003e built for speaker-focused builds — run all four channels full-range, or bridge pairs for a serious 2-channel setup with \u003cstrong\u003e300W x 2 at 4 ohms\u003c\/strong\u003e. Either way, you're getting MICRO-series efficiency in a package that doesn't demand a dedicated amp rack.\u003c\/p\u003e\n\n\u003cp\u003ePower output scales with your load: \u003cstrong\u003e80W x 4 at 4 ohms\u003c\/strong\u003e, \u003cstrong\u003e150W x 4 at 2 ohms\u003c\/strong\u003e, and \u003cstrong\u003e300W x 2 bridged at 4 ohms\u003c\/strong\u003e. The \u003cstrong\u003eClass D design\u003c\/strong\u003e keeps draw low and output clean — no wasted heat, no bloated current demand, just usable power where it counts.\u003c\/p\u003e\n\n\u003cp\u003eLike every amp in the MICRO-U series, the MICRO84U is built for environments that would kill a standard amplifier. The \u003cstrong\u003econformal-coated circuit board\u003c\/strong\u003e seals out moisture, salt air, and dust — making this a legitimate choice for \u003cstrong\u003emarine audio, motorcycle builds, ATVs, UTVs, and any outdoor install\u003c\/strong\u003e where weather exposure is a real concern. This isn't a \"splash-resistant\" marketing claim; it's the same all-weather construction used across the MICRO-U lineup.\u003c\/p\u003e\n\n\u003cp\u003eIntegration is straightforward. \u003cstrong\u003eSelectable REM, VOX, and DC turn-on modes\u003c\/strong\u003e handle compatibility with factory and aftermarket head units, while \u003cstrong\u003eselectable 2CH or 4CH input modes\u003c\/strong\u003e give you flexibility depending on your source configuration. The \u003cstrong\u003evariable 40–400Hz crossover (12dB\/oct)\u003c\/strong\u003e and \u003cstrong\u003eadjustable input sensitivity (0.2–10V)\u003c\/strong\u003e let you tune the amp to your speakers rather than the other way around.\u003c\/p\u003e\n\n\u003cp\u003eAt \u003cstrong\u003e9.1\" x 4.1\" x 1.46\"\u003c\/strong\u003e, the MICRO84U fits under seats, inside fairings, and in console compartments where a conventional 4-channel simply won't go.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cp\u003e• \u003cstrong\u003e4-channel full range Class D amplifier\u003c\/strong\u003e\u003cbr\u003e\n• \u003cstrong\u003e80W x 4 @ 4Ω \/ 150W x 4 @ 2Ω \/ 300W x 2 bridged @ 4Ω\u003c\/strong\u003e\u003cbr\u003e\n• \u003cstrong\u003eConformal-coated PCB\u003c\/strong\u003e — all-weather rated for marine \u0026amp; powersports\u003cbr\u003e\n• \u003cstrong\u003eSelectable REM \/ VOX \/ DC turn-on modes\u003c\/strong\u003e\u003cbr\u003e\n• \u003cstrong\u003eSelectable 2CH \/ 4CH input modes\u003c\/strong\u003e\u003cbr\u003e\n• \u003cstrong\u003eVariable 40–400Hz crossover (12dB\/oct)\u003c\/strong\u003e\u003cbr\u003e\n• \u003cstrong\u003eAdjustable input sensitivity: 0.2–10V\u003c\/strong\u003e\u003cbr\u003e\n• \u003cstrong\u003eCompact chassis: 9.1\" x 4.1\" x 1.46\"\u003c\/strong\u003e\u003cbr\u003e\n• \u003cstrong\u003eRCA input \u0026amp; speaker output harness kits included\u003c\/strong\u003e\u003c\/p\u003e","brand":"Diamond Audio","offers":[{"title":"Default Title","offer_id":43634992611395,"sku":null,"price":499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0637\/9575\/7123\/files\/micro84u_2-3.webp?v=1785959649","url":"https:\/\/www.trinitycaraudio.com\/products\/diamond-audio-4-channel-micro84u-series-full-range-class-d-amplifier","provider":"Trinity Car Audio","version":"1.0","type":"link"}
