It can power four speakers in stereo or support bridged configurations for systems that need fewer, higher-output channels. Its compact dimensions make it a practical choice when installation space is limited.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for listeners building or upgrading an aftermarket system with component speakers, coaxial speakers, or a mixed speaker-and-subwoofer arrangement. It provides rated output of 250 watts per channel at 4 ohms or 500 watts per channel at 2 ohms. For bridged use, it is rated for 1,000 watts x 2 channels at 4 ohms.\u003c\/p\u003e\u003cp\u003eA switch-mode power supply supports stable amplifier operation as vehicle voltage changes. Crunch SPEED-FET MOSFET output devices are used in the amplifier design, while the low-noise preamplifier circuit is intended to keep the incoming signal path controlled. The stated frequency response is 10 Hz to 30 kHz.\u003c\/p\u003e\u003cp\u003eFully adjustable 12 dB-per-octave high-pass and low-pass crossovers help tailor the amplifier to the speakers connected to it. Both filters adjust from 40 Hz to 400 Hz, allowing channels to be configured for full-range speakers or filtered for a particular role in the system. RCA and high-level inputs provide connection options for aftermarket and factory-style audio systems.\u003c\/p\u003e\u003cp\u003eThe CRA-2000.4 supports four-channel stereo, dual stereo bridged, stereo plus bridged mono, and dual bridged mono operation modes. Signal-sensing remote turn-on can simplify integration with a source unit, while overload and speaker-short protection are monitored through an LED diagnostic system. It is a universal amplifier rather than a vehicle-specific fitment part.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Class D Design:\u003c\/strong\u003e Delivers efficient multi-channel amplification in a compact chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible Power Ratings:\u003c\/strong\u003e Supports 4-ohm, 2-ohm, and 4-ohm bridged speaker configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Crossovers:\u003c\/strong\u003e High-pass and low-pass filters adjust from 40 Hz to 400 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA And High-Level Inputs:\u003c\/strong\u003e Accommodates aftermarket radios and compatible factory audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSMPS Power Supply:\u003c\/strong\u003e Helps maintain stable operation as vehicle voltage varies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Diagnostics:\u003c\/strong\u003e LED indication monitors overload and speaker-short protection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe amplifier uses an aluminum heat sink with Crunch Quick Thermal Dispersion Technology to help manage operating heat. Nickel-plated brass connection terminals are intended to resist corrosion, and the screw-down terminal design provides accessible connection points. The black amplifier chassis measures 8.5 inches long, 4.25 inches wide, and 2.1 inches high.\u003c\/p\u003e\u003cp\u003eUse 4 AWG power and ground wiring at the amplifier terminals, and use up to 8 AWG speaker wire at the speaker terminals. The amplifier requires external 75A fusing, and it supports a minimum 2-ohm load per unbridged channel or a minimum 4-ohm bridged load. Set gains and crossover points to suit the connected speakers and the source unit's output level.\u003c\/p\u003e","brand":"Crunch","offers":[{"title":"Default Title","offer_id":45621485600838,"sku":"CRA-2000-4","price":218.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61T1IXySyHL.jpg?v=1784371586","url":"https:\/\/audiowatt.store\/products\/crunch-cra-2000-4-2000w-four-channel-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
