Introducing the “Sundown Full Bridge” line of amplifiers, “SFB” for short. These amps pack a huge punch in a fairly small footprint. Due to the full bridge technology, these amplifiers are not strappable however you can line up multiple amps together to create a massive powerhouse in the same, if not smaller, footprint of your standard half bridge predecessors for a fraction of the cost.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eAll of the SFB 4ch amp’s power ratings are listed at the 1ohm rating. For instance, the SFB-500.4 is 500Wrms at 1ohm per channel. This allows you to run many more speakers together in a multitude of different wiring configurations than using a standard Class A\/B\/D half bridge design. These are the perfect amplifiers for large systems where you have a plethora of pro drivers in multiple doors or line arrays.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eAll SFB mono amplifiers are full range. This not only allows you to run subwoofers as you would most mono amps, but you can also run a large arrays of mids\/highs on these amps as well. The crossovers on the mono SFB amps can attenuate from 15hz all the way up to 20khz. This allows you to set bandpass crossover points and dial in whatever frequency you desire for your setup no matter the type of speaker you are using.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eThe SFB series amps are considered to be a “Brazilian Style” of amplifier. This technology is not new and has been around for quite a while however, the use of them has surged dramatically in the past few years. These little amplifiers are known to be the best bang for your buck. If you are looking for raw power on a budget, look no further than the SFB Series from Sundown Audio.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/files\/SFB-Amp-Manual.pdf?v=1688793255\"\u003eProduct Manual\u003c\/a\u003e \u003cmeta charset=\"UTF-8\"\u003e\u003c\/p\u003e\n\u003cdiv class=\"cus-flex\"\u003e\n\u003cdiv class=\"box-1\"\u003e\n\u003ch3 class=\"el-title uk-text-danger uk-margin-top uk-margin-remove-bottom\" data-mce-fragment=\"1\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv class=\"el-content uk-panel uk-margin-top\" data-mce-fragment=\"1\"\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003eDigital Class-D Mono Block Amplifier\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eDual MOS-FET PWM Power Supply\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e1 Ohm Stable Load\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e12 dB\/Octave – Variable Low Pass Filter\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e12 dB\/Octave – Variable High Pass Filter\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e9 dB\/Octave – Variable Bass Boost\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e4 Way Protection Ciruit (Thermal, Voltage, Speaker Short, DC Offset)\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"box-2\"\u003e\n\u003ch3 class=\"el-title uk-text-danger uk-margin-top uk-margin-remove-bottom\" data-mce-fragment=\"1\"\u003eSpecifications for the SFB8000:\u003c\/h3\u003e\n\u003cdiv class=\"el-content uk-panel uk-margin-top\" data-mce-fragment=\"1\"\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003e1 ohm Mono RMS 8000W\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e2 ohm Mono RMS 5000W\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003e4 ohm Mono RMS 3250W\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eRecommended Fuse Rating 350A x 2\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eLow Pass Filter (Variable) 80Hz-20kHz\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eHigh Pass Filter (Variable) 15Hz-80Hz\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eBass Boost @ 50Hz 0-12dB\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eInput Sensitivity 5V Max\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eS\/N Ratio 100dB\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eWorking Voltage 10.5v-15.5v\u003c\/li\u003e\n\u003cli data-mce-fragment=\"1\"\u003eDimensions 9.00\" x 16.50\" x 2.75\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sundown Audio","offers":[{"title":"Default Title","offer_id":45386393682230,"sku":"RA-SFB8000D","price":419.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/6669\/9062\/products\/sundown-audio-sfb-8000d-8000w-full-range-car-audio-amplifieramp-423679.png?v=1689636972"},{"product_id":"sundown-audio-sdx-1200-1-1200w-marine-grade-powersports-audio-amplifier-amp","title":"SDX-1200.1 Weatherproof Mono Amplifier","description":"\u003cul\u003e\n\u003cli class=\"MsoNormal\"\u003e1,200 x 1 @ 1 ohm RMS\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e825 x 1 @ 2 ohms RMS\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003e450 x 1 @ 4 ohms RMS\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eVariable 12dB low-pass filter: 50Hz - 250Hz\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eVariable 12dB bass boost \u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eDC auto-sensing turn on\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eThermal, voltage, speaker short, and dc-offset protection circuitry\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eWater resistant\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eHeavy cast aluminum heat sink\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eRemovable audio control cover\u003c\/li\u003e\n\u003cli class=\"MsoNormal\"\u003eWired remote control\u003cspan style=\"mso-spacerun: yes;\"\u003e \u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eGet ready to experience the power and versatility with the water-resistant SDX amp!

Introducing the “Sundown Full Bridge” line of amplifiers, “SFB” for short. These amps pack a huge punch in a fairly small footprint. Due to the full bridge technology, these amplifiers are not strappable however you can line up multiple amps together to create a massive powerhouse in the same, if not smaller, footprint of your standard half bridge predecessors for a fraction of the cost.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eAll of the SFB 4ch amp’s power ratings are listed at the 1ohm rating. For instance, the SFB-500.4 is 500Wrms at 1ohm per channel. This allows you to run many more speakers together in a multitude of different wiring configurations than using a standard Class A\/B\/D half bridge design. These are the perfect amplifiers for large systems where you have a plethora of pro drivers in multiple doors or line arrays.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eAll SFB mono amplifiers are full range. This not only allows you to run subwoofers as you would most mono amps, but you can also run a large arrays of mids\/highs on these amps as well. The crossovers on the mono SFB amps can attenuate from 15hz all the way up to 20khz. This allows you to set bandpass crossover points and dial in whatever frequency you desire for your setup no matter the type of speaker you are using.\u003c\/p\u003e\n\u003cp style=\"font-weight: 400;\"\u003eThe SFB series amps are considered to be a “Brazilian Style” of amplifier. This technology is not new and has been around for quite a while however, the use of them has surged dramatically in the past few years. These little amplifiers are known to be the best bang for your buck. If you are looking for raw power on a budget, look no further than the SFB Series from Sundown Audio.\u003c\/p\u003e\n\u003cp\u003e\u003ca
