It provides a dedicated mono output for drivers who want to add low-frequency reinforcement without using a multi-channel amplifier. RMS output is rated at 425 watts at 2 ohms or 285 watts at 4 ohms.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for vehicle audio systems using a compatible 2-ohm or 4-ohm subwoofer load. Its mono-only configuration keeps setup focused on bass reproduction, while the built-in bass control provides an accessible way to adjust output from the listening position. A wired bass remote is included.\u003c\/p\u003e\u003cp\u003eThe SA-2100.1 uses a variable electronic crossover with a 12 dB-per-octave slope to help tailor the amplifier for a subwoofer application. A variable subsonic filter from 10 to 40 Hz helps limit very low-frequency content. Switchable bass boost and phase adjustment add further tuning flexibility.\u003c\/p\u003e\u003cp\u003eFor signal integration, the amplifier provides RCA inputs as well as high-level speaker inputs for systems that do not have RCA preamp outputs. Its 0.2 to 9V variable input-voltage range supports matching the amplifier to different source-unit signal levels. The frequency response is specified from 10 Hz to 500 Hz.\u003c\/p\u003e\u003cp\u003eCrunch equips the SA-2100.1 with SPEED-FET MOSFET output components, a pulse-width-modulated power supply, and QTD aluminum heat-sink technology. Nickel-plated brass terminals are used for the power and speaker connections. LED protection diagnostics monitor overload and speaker-short conditions.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono Class AB Output:\u003c\/strong\u003e Delivers dedicated amplification for a compatible subwoofer system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e425W RMS at 2 Ohms:\u003c\/strong\u003e Provides its highest listed continuous output into a 2-ohm load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Electronic Crossover:\u003c\/strong\u003e Lets you tailor the amplifier's frequency filtering for bass duty.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubsonic Filter:\u003c\/strong\u003e Adjustable 10-40 Hz filtering helps manage ultra-low-frequency content.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass Remote Included:\u003c\/strong\u003e Gives you convenient wired adjustment of bass level.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA and High-Level Inputs:\u003c\/strong\u003e Supports aftermarket radios and factory-radio integration.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe SA-2100.1 combines a Class AB amplifier platform with a QTD aluminum heat sink intended to disperse heat during operation. SPEED-FET MOSFET components and a pulse-width-modulated power supply are part of its power-stage design. Nickel-plated brass connection terminals are specified for corrosion resistance and secure cable attachment.\u003c\/p\u003e\u003cp\u003eMount the amplifier on a secure surface with adequate ventilation and do not mount it upside down. Installation requires 4-gauge power and ground wiring, while the speaker terminal accepts 12-gauge wire. Match the connected subwoofer system to a supported 2-ohm or 4-ohm load, then set gain, crossover, subsonic filter, bass boost, and phase appropriately for the system.\u003c\/p\u003e","brand":"Crunch","offers":[{"title":"Default Title","offer_id":45624996102214,"sku":"SA-2100-1","price":174.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/619a1t_z62L.jpg?v=1784373740","url":"https:\/\/audiowatt.store\/products\/crunch-sa-2100-1-smash-series-monoblock-class-ab-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
