It delivers up to 4,000 watts RMS into a 1-ohm load, with lower rated output options at 2 and 4 ohms. It is intended for installations that need a dedicated amplifier for low-frequency reproduction rather than full-range speakers.\u003c\/p\u003e\u003cp\u003eThis amplifier suits builders matching one or more subwoofers to a high-output mono channel. Its variable low-pass crossover and subsonic filter allow the bass range to be tailored to the subwoofers and enclosure. An adjustable bass boost and phase control provide further system-tuning options.\u003c\/p\u003e\u003cp\u003eThe BXX4000.1D uses Super D\/Class D amplification and an Ultra-Fi MOSFET output circuit. Hifonics also specifies an NGSD digital chip design as part of its power-amplification platform. The design is paired with an aluminum alloy heat sink for heat dissipation during operation.\u003c\/p\u003e\u003cp\u003eFor signal integration, the amplifier uses RCA audio inputs and provides RCA connections for master\/slave linking. It is strappable with a second compatible amplifier, allowing a linked pair to be used in a larger bass system. A wired remote bass-level control is included for convenient adjustment from the listening position.\u003c\/p\u003e\u003cp\u003eThe amplifier is 1-ohm stable and requires subwoofers to be wired to a supported final impedance. It includes power and protect status indicators, built-in diagnostics, and protection circuitry for thermal, overload, and speaker-short conditions. Its high-current installation requirements make careful power, ground, fuse, and ventilation planning important.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4,000W RMS at 1 Ohm:\u003c\/strong\u003e Supplies substantial mono power for a properly matched subwoofer load.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuper D\/Class D Topology:\u003c\/strong\u003e Provides an efficient amplifier platform for dedicated bass systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e Adjusts the subwoofer passband from 35 to 250 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubsonic Filter:\u003c\/strong\u003e Filters frequencies from 15 to 35 Hz for enclosure-aware tuning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrappable Operation:\u003c\/strong\u003e Supports master\/slave linking with another compatible amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Lets the user adjust bass level from the front seat.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe BXX4000.1D is a single-channel amplifier with an aluminum alloy heat sink, Ultra-Fi MOSFET circuitry, and LED power\/protect indicators. Its control panel includes adjustments for input level, low-pass crossover, subsonic filtering, bass boost, and phase. RCA input and linking connections support use in dedicated subwoofer systems and paired-amplifier configurations.\u003c\/p\u003e\u003cp\u003eInstall the amplifier in a secure, dry, well-ventilated location with space around the heat sink. Use appropriately sized power and ground wiring, an external 275A fuse, and a solid chassis ground; the listed power and ground terminal capacity is 0 AWG. Match the connected subwoofer wiring to a final load no lower than 1 ohm, then set gain and filters carefully to suit the enclosure and system.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631919325254,"sku":"BXX4000-1D","price":658.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71dC86EjckL.jpg?v=1784388191","url":"https:\/\/audiowatt.store\/products\/hifonics-bxx4000-1d-brutus-4000w-mono-subwoofer-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
