Its single-channel configuration is intended for subwoofer duty rather than full-range multi-speaker amplification. It provides rated output of 195 watts RMS x 1 at 2 ohms or 120 watts RMS x 1 at 4 ohms.\u003c\/p\u003e\u003cp\u003eThis amplifier suits listeners building a straightforward bass upgrade with one subwoofer or a properly wired subwoofer group. It operates in mono only and is rated stable down to a 2-ohm load. High-level inputs also allow it to work with many factory or aftermarket radios that do not provide RCA preamp outputs.\u003c\/p\u003e\u003cp\u003eThe SA-1100.1 uses a Class A\/B circuit topology with Crunch SPEED-FET MOSFET output components and a pulse-width-modulated power supply. Its low-noise preamplifier circuit is designed to accept the source signal before amplification. A variable input sensitivity range of 0.2 to 9 volts helps match the amplifier to different source-unit output levels.\u003c\/p\u003e\u003cp\u003eSystem tuning tools include a variable electronic crossover with a 12 dB-per-octave slope, a 40 to 300 Hz low-pass filter, and a 10 to 40 Hz subsonic filter. Switchable bass boost offers 0, +6, or +12 dB settings, while selectable phase adjustment provides 0 or 180 degrees. A wired bass remote is included for adjusting bass level from the cabin.\u003c\/p\u003e\u003cp\u003eFor an upgrade path, the SA-1100.1 can be used as the dedicated bass amplifier alongside a separate amplifier for door speakers. Its 10 to 500 Hz frequency response and low-pass filtering support integration with higher-frequency speakers. RCA and speaker-level input options provide flexibility when planning either an aftermarket-radio or factory-radio installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono Subwoofer Output:\u003c\/strong\u003e Single-channel design focuses amplification on a bass speaker system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm RMS Rating:\u003c\/strong\u003e Delivers 195 watts RMS x 1 at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e Adjusts the upper bass cutoff from 40 to 300 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubsonic Filter:\u003c\/strong\u003e Adjustable 10 to 40 Hz filtering helps manage very low frequencies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Input Options:\u003c\/strong\u003e RCA and high-level inputs support varied source units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Lets you adjust bass level from the listening position.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe SA-1100.1 has a QTD aluminum heat sink intended to disperse heat, along with nickel-plated brass connection terminals. Screw-down connectors provide tool-accessible cable attachment points. LED diagnostic circuitry monitors overload and speaker-short protection conditions.\u003c\/p\u003e\u003cp\u003eMount the amplifier securely in a dry, ventilated location and avoid mounting it upside down. The 12-volt and ground terminals accept up to 4 AWG cable, while the speaker terminals accept up to 12 AWG wire. Use either RCA or supplied-harness high-level signal wiring, match the connected subwoofer load to the amplifier's 2- or 4-ohm ratings, and set gain and filters during final system tuning.\u003c\/p\u003e","brand":"Crunch","offers":[{"title":"Default Title","offer_id":45624832786502,"sku":"SA-1100-1","price":110.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61o-dw7DiqL.jpg?v=1784373644","url":"https:\/\/audiowatt.store\/products\/crunch-sa-1100-1-smash-series-monoblock-class-ab-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
