It is at the cutting edge of technology and performance. \u003c\/h4\u003e\n\u003ch4\u003eWith more than 4000W RMS in class-D (very high efficiency), it pushes the limits of amplification. To achieve this, we spent three years in development to bring together the best in high-fidelity and in high-output. \u003cspan\u003eWe also used the best components available. \u003c\/span\u003e\n\u003c\/h4\u003e\n\u003cp\u003e\u003cspan\u003eThe power supply is cut by the most efficient MOSFETs available from the best manufacturer, International Rectifier (USA). They support 640A each, 175°C and there are 12 of them. We used 6 transformers to distribute the load and the temperature. \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe energy storage at the power supply output is provided by 23 Elna capacitors, with low resistance and ultra fast. They withstand 105°C, but never exceed 60°C even after 5 days at full output! On the power stage, we used MOSFETs from International Rectifier which support 280A each.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003e\u003cspan\u003eTo verify the correct operating balance of the RFL4001D, we monitored it with a $35,000 thermal racing camera. This allowed us to monitor the temperature of each component and the width \/ thickness of each track on the PCB. It's been a painstaking job, but the MTX RFL4001D performs much better than our wildest dreams. The RFL4001D is the highest performing amp ever built by MTX.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cspan\u003e\u003cspan\u003eCheck out this video by MTX dealer AV-DC:\u003c\/span\u003e\u003c\/span\u003e\u003c\/h4\u003e\n\u003cp\u003e\u003ciframe src=\"https:\/\/www.youtube-nocookie.com\/embed\/9i6zyLujFJg\" height=\"315\" width=\"560\" allowfullscreen=\"\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003c\/h4\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cp\u003e• High End amplifier ; high-end clean output power, high-end sound quality, high-end components and high-end construction. \u003cbr\u003e• 1Ω to 8Ω compatible.\u003cbr\u003e• Flexible active crossover with subsonic filter.\u003cbr\u003e• \u003cstrong\u003eBridge 2 amps together to create extreme output power of 8000W RMS\u003c\/strong\u003e\u003cbr\u003e• EBC included (External Bass Control)\u003cbr\u003e• 4 x 50mm2 power connections\u003c\/p\u003e\n\u003ch2\u003eSpecifications RFL4001D\u003c\/h2\u003e\n\u003cp\u003e• Class D Mono Block amplifier (1 channel)\u003c\/p\u003e\n\u003cp\u003e• CEA2006 certified output power :\u003cbr\u003e-\u003cstrong\u003e 1x 4000 watts RMS @ 1Ω THD+N ≤1%\u003c\/strong\u003e\u003cbr\u003e- 1x 2400 watts RMS @ 2Ω THD+N ≤1%\u003cbr\u003e- 1x 1500 watts RMS @ 4Ω THD+N ≤1%\u003cbr\u003e• Damping factor : \u0026gt;500\u003cbr\u003e• Bridge mode function (2 amps)\u003cbr\u003e• Active crossover :\u003cbr\u003e- Low Pass (LPF) 24dB\/Oct variable from 40Hz to 150Hz\u003cbr\u003e- Subsonic filter 24dB\/Oct at 20Hz\u003cbr\u003e• Phase selection 0° or 180°\u003cbr\u003e• Signal\/noise ratio (1 watt) : \u0026gt;95dB\u003cbr\u003e• THD+Noise (Distortion) (1 watt) : ≤0,08%\u003cbr\u003e• Frequency response (±1dB) : 10Hz-150Hz\u003cbr\u003e• RCA input sensitivity : 200mV - 6V\u003cbr\u003e• EBC (External Bass Control) included\u003cbr\u003e• Dimensions : 626mm x 204mm x 59mm\u003c\/p\u003e\n\u003cp\u003ePlease note: This high powered competition amplifier should be installed by a professional car audio store, with supporting power upgrades completed on your vehicle such as the ‘big three’, 2-3 matching\/new batteries, high quality dual 0 gauge wiring and earthing.
