It can be used to drive a pair of speakers in stereo or a compatible speaker load in bridged mono. Its high-level and RCA input options support use with many aftermarket and factory-style source-unit installations.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for listeners building a system around upgraded full-range speakers, component speakers, or a bridged subwoofer application. It provides 250 watts per channel at 4 ohms, 500 watts per channel at 2 ohms, or 1,000 watts bridged at 4 ohms. Adjustable high-pass and low-pass crossovers help direct the appropriate frequency range to the connected speakers.\u003c\/p\u003e\u003cp\u003eThe CRA-1000.2 uses a Class D amplifier topology designed for efficient operation in a compact chassis. Crunch specifies a switch-mode power supply and SPEED-FET MOSFET output-device technology. A low-noise preamplifier circuit is used to help keep the incoming source signal clean through amplification.\u003c\/p\u003e\u003cp\u003eSystem tuning is handled through fully adjustable 12 dB-per-octave crossover controls. Both the high-pass and low-pass ranges are adjustable from 40 Hz to 400 Hz, allowing the amplifier to be configured for full-range speakers or a low-frequency application. The input sensitivity range is specified at 0.2 to 6 volts.\u003c\/p\u003e\u003cp\u003eFor an upgrade path, the amplifier offers RCA inputs for aftermarket signal sources and high-level inputs for systems without RCA outputs. Signal-sensing remote turn-on can simplify integration with compatible factory audio systems. An output connection can also provide signal to a second amplifier in a larger multi-amplifier setup.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo-Channel Class D Design:\u003c\/strong\u003e Provides efficient power in a compact car-audio amplifier format.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Power Configuration:\u003c\/strong\u003e Runs stereo at 2 or 4 ohms, or bridged at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable 12 dB Crossovers:\u003c\/strong\u003e Helps match output frequency range to speakers or subwoofers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA And High-Level Inputs:\u003c\/strong\u003e Supports aftermarket radios and compatible factory-audio integration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch-Mode Power Supply:\u003c\/strong\u003e Designed to provide stable amplifier power delivery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Status Indicator:\u003c\/strong\u003e LED diagnostics monitor overload and speaker-short protection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe CRA-1000.2 has a black compact chassis with an aluminum heat sink using Crunch Quick Thermal Dispersion Technology. Nickel-plated brass connection terminals are designed to resist corrosion, while screw-down connectors provide secure cable attachment. The amplifier is specified with 4 AWG power and ground terminals and 8 AWG speaker terminals.\u003c\/p\u003e\u003cp\u003eMount the amplifier securely in a location with adequate ventilation and do not mount it upside down. Crunch specifies an external 50A fuse and recommends 4-gauge copper power and ground cable for this model. Use RCA inputs when available, or connect the high-level input for source units without RCA outputs; set crossover and level controls to suit the connected speakers and system design.\u003c\/p\u003e","brand":"Crunch","offers":[{"title":"Default Title","offer_id":45621156675654,"sku":"CRA-1000-2","price":146.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/51IUYIQAGYL.jpg?v=1784371401","url":"https:\/\/audiowatt.store\/products\/crunch-cra-1000-2-2-channel-class-d-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
