The FA1-900.5 is a 900 watt 1 ohm stable (channel 5 only) car audio amplifier. Formula amplifiers feature DC Sensing to allow any amplifier to be easy integrated into an OEM system by simply adapting a RCA cable from the source unit. Bass remote is included.\u003cbr data-mce-fragment=\"1\"\u003eLow Noise Preamplifier Circuit. Q-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion.\u003cbr data-mce-fragment=\"1\"\u003eRCA Inputs. Nickel Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.\u003cbr data-mce-fragment=\"1\"\u003eHigh Level Inputs. DC SIGNAL SENSE: The DC SIGNAL SENSE switch will allow the amp to turn on when a signal is received on the RCA inputs, so an amplifier remote turn on wire is not needed to turn on the amplifier. This feature can also be turned off.\u003cbr data-mce-fragment=\"1\"\u003eCrossover Type. Variable electronic crossovers allow for complete control of the sound.\u003cbr data-mce-fragment=\"1\"\u003eElectronic Equalizer. Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers. Check specifications for specific frequencies for this amplifier.\u003cbr data-mce-fragment=\"1\"\u003eClass \/ Topology. Innovative use of Class SQ (Class A\/B) for full range and a Class Q1 (Class-D) amplifier to drive the subwoofer frequencies.\u003cbr data-mce-fragment=\"1\"\u003eOutput Device Technology. FLUID-FETS: MB Quart output devices, FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers.\u003cbr data-mce-fragment=\"1\"\u003eHeavy duty heat-sink efficiently moves heat from the MOSFET where it can be cooled.\u003cbr data-mce-fragment=\"1\"\u003ePower Supply. Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to product efficient power without taxing the vehicle electrical system.\u003cbr data-mce-fragment=\"1\"\u003eOutput Connections. Heavy duty connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier.\u003cbr data-mce-fragment=\"1\"\u003eConnection Type. Secure connection for all power, ground and speaker connections.\u003cbr data-mce-fragment=\"1\"\u003eLED System Protection Circuitry Diagnostics. Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel.\u003cbr data-mce-fragment=\"1\"\u003eBass Remote Included. Included on mono and 5 channel amplifiers. This allows the driver to make subtle changes to the bass response of the audio system from the seated listening position.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0081\/3472\/1600\/files\/61tK0nJo1ZL._AC_SL1500_grande_0a9807c6-e334-4e73-ab14-f6dd3e14a0a8_480x480.webp?v=1708507391\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0081\/3472\/1600\/files\/61cbtAwzKEL._AC_SL1500_1024x1024_54316703-d8ee-47eb-9442-24cd43607aa4_480x480.webp?v=1708507402\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\u003cspan style=\"color: #c40505;\"\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003eWeight 10.3 lbs\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Class: Class SQ + Class Q1 Mono (Class A\/B + Class D)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Total Channels: 5\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Max Power (watts) : 900\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Power @ 1 Ohm (ch x watts): 1 x 500 (Channel 5 only)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Power @ 2 Ohms (ch x watts): 4 x 100 + 1 x 350\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Power @ 4 Ohms (ch x watts): 4 x 60 + 1 x 250\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Crossover: Electronic\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Variable High Pass Crossover 12dB per Octave: CH1 \u0026amp; CH2: Switched Full\/HPF 50Hz-500Hz, CH3 \u0026amp; CH4: Switched Full\/HPF 50Hz-250Hz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Variable Low Pass Crossover 12dB per Octave: CH5 (Sub): 50Hz-250Hz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Bass Boost : 0-12dB\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Subsonic Filter: 10Hz-40Hz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Variable Voltage: 0.02-9V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Signal to Noise: \u0026gt;93dB\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Frequency Response: 10Hz-45KHz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Total Harmonic Distortion (THD): \u0026lt; 0.5%\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Speaker Level Audio Inputs: RCA Jack\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Power Terminal 12v\/GND: 4 AWG\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Speaker Terminal Wire Gauge: 12 AWG\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"color: #000000;\"\u003e Amp Fusing: 40A x 2\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MB QUART","offers":[{"title":"Default Title","offer_id":42680689885232,"sku":"MB FA1-900.5","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0629\/7033\/1184\/files\/51ZIHQJkmKL._AC_SL1500_grande_e15f5671-2889-428d-8e84-0b5232604b31.webp?v=1767221029","url":"https:\/\/fuegobassshop.com\/products\/mb-quart-fa1-900-5-formula-900-watt-5-channel-car-audio-amplifier","provider":"Fuego Bass Shop","version":"1.0","type":"link"}
