It can be used to drive front and rear full-range speakers, or configured in bridged pairs for higher-output applications. Its four-channel layout gives installers flexibility when planning a speaker-focused system upgrade.\u003c\/p\u003e\u003cp\u003eRated for 115 watts RMS per channel at 4 ohms and 235 watts RMS per channel at 2 ohms, the CRA-950.4 is suited to compatible aftermarket speakers that need more power than a head unit can supply. It also supports two-channel bridged operation at 4 ohms, rated at 475 watts RMS per bridged channel. This makes it practical for systems that combine full-range speakers with a bridged subwoofer channel arrangement.\u003c\/p\u003e\u003cp\u003eThe amplifier uses an efficient Class D topology designed to reduce current draw and heat compared with less-efficient amplifier designs. Its switch-mode power supply is intended to maintain stable amplifier operation as vehicle voltage changes. Crunch SPEED-FET MOSFET output devices and a low-noise preamplifier circuit support controlled amplification with minimal distortion.\u003c\/p\u003e\u003cp\u003eBuilt-in electronic crossover controls help tailor the signal sent to each speaker group. Adjustable high-pass and low-pass filters cover a 40 Hz to 400 Hz range, allowing installers to limit bass sent to smaller speakers or direct bass-focused channels toward compatible subwoofers. Separate crossover sections for the channel pairs allow system tuning around the speakers being used.\u003c\/p\u003e\u003cp\u003eThe CRA-950.4 accepts both RCA low-level and speaker-level input signals, supporting integration with many aftermarket and factory audio systems. DC signal-sensing turn-on can simplify installation when using high-level inputs. It is a compact amplifier platform for a properly matched four-speaker system, a mixed mono setup, or a bridged two-channel configuration.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Class D Design:\u003c\/strong\u003e Provides efficient amplification for multi-speaker vehicle audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e950W Total RMS Output:\u003c\/strong\u003e Delivers up to 235 watts RMS across four 2-ohm channels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridged Channel Capability:\u003c\/strong\u003e Supports two 475-watt RMS channels at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Electronic Crossovers:\u003c\/strong\u003e Helps match frequency output to speakers or subwoofers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA And High-Level Inputs:\u003c\/strong\u003e Supports aftermarket and many factory-system signal connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Circuitry:\u003c\/strong\u003e Includes overload and speaker-short protection for system safeguarding.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe CRA-950.4 uses a compact amplifier chassis with an aluminum heat sink designed to disperse heat. Nickel-plated brass connection terminals and screw-down connectors are provided for secure cable connections.

The amplifier should be mounted to a secure, ventilated surface and not upside down. Match each channel to the correct speaker impedance: 2 ohms minimum per unbridged channel or 4 ohms minimum per bridged channel.\u003c\/p\u003e","brand":"Crunch","offers":[{"title":"Default Title","offer_id":45621682536518,"sku":"CRA-950-4","price":164.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61wU4fgna6L.jpg?v=1784371679","url":"https:\/\/audiowatt.store\/products\/crunch-cra-950-4-four-channel-class-d-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
