It carries all the hallmark iconic SFB features — dual MOS-FET PWM power supply, variable low and high pass filters, 0–12dB bass boost, and four-way protection circuitry — while adding a 250A fuse rating to match its serious power demands. The smart three-speed temperature-activated cooling fan keeps it running cool under heavy loads, making it a top pick for enthusiasts looking to push high-power subwoofer setups without stepping into multi-amp territory.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial;\"\u003e\u003cstrong\u003e\u003cfont size=\"5\"\u003eFeatures:\u003c\/font\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eDigtal Class-D Mono Block Amplifer\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eDual MOS-FET PWM Power Supply\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003e1 Ohm Stable Load\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003e12 dB\/Octave - Variable Low Pass Filter\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003e0 to 12dB - Variable Bass Boost\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003e4 Way Protection Circuit (Thermal, Voltage Speaker Short and DC Offset)\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eWired Remote Control with Clipping Indicator\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial;\"\u003e\u003cstrong\u003e\u003cfont size=\"5\"\u003eSpecifications:\u003c\/font\u003e\u003cbr\u003e\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003e1Ω Mono RMS: 3000W\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003e2Ω Mono RMS: 2000W\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003e4Ω Mono RMS: 1100W\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eRecommended Fuse Rating: 250A\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eSignal Noise Ratio: 86dB\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eWorking Voltage: 10.5V - 15.5V DC\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eWidth: 229mm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eLength: 210mm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eHeight: 64mm\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eWidth: 9.00\"\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eLength: 8.25\"\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-family: Arial;\"\u003eHeight: 2.50\"\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"ql-block\" data-block-id=\"block-nVKJLid67e\"\u003e\u003c\/div\u003e","brand":"SUNDOWN AUDIO","offers":[{"title":"Default Title","offer_id":52223387533613,"sku":"SFB-3000D","price":269.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/0805\/3037\/files\/3007906.jpg?v=1784079112","url":"https:\/\/audiosavings.com\/products\/lowersubstitute-e5422","provider":"Audio Savings","version":"1.0","type":"link"}
