It is suited to cars, motorcycles, and UTVs that need a small-footprint amplifier for front and rear speakers or a mixed stereo-and-subwoofer setup. Its full-range Class-D design supports a broad range of speaker applications.\u003c\/p\u003e\u003cp\u003eRated at 100 watts per channel at 4 ohms and 200 watts per channel at 2 ohms, the HCM-800.4D can provide substantially more output than a typical radio's built-in amplifier. It can also be bridged into two channels at 4 ohms for applications requiring more power per channel. Variable high-pass and low-pass crossovers help tailor the signal to the speakers connected.\u003c\/p\u003e\u003cp\u003eThe amplifier uses a mass-loaded extruded aluminum heat sink to manage heat without fan cooling. Ultra-Fi MOSFET output devices and a full-range Class-D chipset support efficient operation in a compact chassis. Its published frequency response is 10Hz to 25kHz, making it suitable for full-range speaker amplification.\u003c\/p\u003e\u003cp\u003eInstallation flexibility comes from speaker-level inputs as well as nickel-plated RCA inputs. The input-level range of 0.2V to 5V accommodates many aftermarket and factory-source integration approaches. A delayed turn-on circuit is designed to reduce turn-on and turn-off noise with compatible source units.\u003c\/p\u003e\u003cp\u003eThe HCM-800.4D fits well as the speaker amplifier in a complete upgraded system, including systems that use a separate mono amplifier for subwoofers. It can run four speakers in stereo or operate in a two-channel bridged arrangement when matched to proper 4-ohm loads. A supplied bass remote provides adjustment relative to the amplifier's bass-control setting.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Class-D Design:\u003c\/strong\u003e Powers four speakers efficiently from a compact amplifier chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e800-Watt Maximum Output:\u003c\/strong\u003e Delivers up to 4 x 200 watts at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Channels:\u003c\/strong\u003e Supports two-channel bridged operation with 4-ohm speaker loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Electronic Crossovers:\u003c\/strong\u003e Helps direct appropriate frequency ranges to connected speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh- and Low-Level Inputs:\u003c\/strong\u003e Works with RCA outputs or speaker-level source signals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple Protection Circuits:\u003c\/strong\u003e Provides over\/under-voltage, short-circuit, and thermal protection.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe HCM-800.4D has a black, compact chassis with a mass-loaded extruded aluminum heat sink and CNC-machined aluminum Hifonics and Colossus badging. Its multi-layer PCB and surface-mount construction reduce component count, while molded angled power, ground, and speaker terminals support a cleaner wiring profile. The amplifier does not use fan cooling.\u003c\/p\u003e\u003cp\u003eMount the amplifier securely in a location with adequate ventilation and use the recommended cable and fuse provisions. Hifonics specifies 4 AWG power and ground terminals, 12 AWG speaker terminals, and an external 80A fuse for this model. Use RCA or speaker-level input as appropriate, configure the crossover for the connected speakers, and do not bridge the amplifier below a 4-ohm load.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631922634822,"sku":"HCM800-4D","price":292.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/615bbAFrxLL.jpg?v=1784389360","url":"https:\/\/audiowatt.store\/products\/hifonics-hcm-800-4d-800w-4-channel-class-d-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
