{"product_id":"hifonics-bxx2000-1d","title":"Hifonics BXX2000-1D 1-Ohm Mono Subwoofer Amplifier","description":"\u003cp\u003eThe Hifonics BXX2000-1D is a mono car audio amplifier designed to power a subwoofer system from a single channel. It is stable to a 1-ohm final load and provides selectable output ratings for 1-, 2-, and 4-ohm subwoofer wiring configurations. This makes it suited to systems that need dedicated low-frequency amplification rather than full-range speaker channels.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for listeners building a bass-focused upgrade around compatible passive subwoofers. Its electronic low-pass crossover, subsonic filter, bass boost, and phase adjustment allow the subwoofer output to be tailored to the rest of the vehicle audio system. RCA inputs support connection from a source unit or signal processor with compatible preamp outputs.\u003c\/p\u003e\u003cp\u003eThe BXX2000-1D uses Super D-Class circuitry with a pulse-width-modulated MOSFET power supply and Ultra-Fi MOSFET output devices. Its published frequency response is 10 Hz to 250 Hz, covering the range typically used for subwoofer reproduction. A variable low-pass filter helps keep higher frequencies out of the subwoofer channel for a cleaner blend with main speakers.\u003c\/p\u003e\u003cp\u003eFor system tuning, the amplifier provides adjustable input sensitivity, 0 to 10 dB bass boost, a 15 to 35 Hz subsonic filter, and variable phase control from 0 to 180 degrees. These controls allow an installer to match the amplifier to the source signal, enclosure design, subwoofer capabilities, and vehicle acoustics. The included wired bass-level remote provides convenient level adjustment from the cabin.\u003c\/p\u003e\u003cp\u003eThe BXX2000-1D is a practical fit for an aftermarket subwoofer stage using a compatible final impedance of 1, 2, or 4 ohms. Dual speaker terminals simplify connecting multiple subwoofer leads while maintaining the correct final load. It can also feed another amplifier through its RCA outputs when expanding a larger audio system.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono Subwoofer Channel:\u003c\/strong\u003e Dedicated single-channel design for powering a bass system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-Ohm Stable Operation:\u003c\/strong\u003e Supports a properly wired final load as low as 1 ohm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Power Ratings:\u003c\/strong\u003e Delivers rated output at 1-, 2-, or 4-ohm loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectronic Low-Pass Crossover:\u003c\/strong\u003e Adjusts the upper frequency limit sent to subwoofers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWired Bass Remote:\u003c\/strong\u003e Enables convenient subwoofer-level adjustment from the driver area.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Diagnostics:\u003c\/strong\u003e LED indicators show normal operation or protection status.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe amplifier uses a heavy-duty aluminum-alloy heat sink to help manage operating heat.

The power and ground terminals accept 0 AWG cable, while the speaker terminals accept 10 AWG wire. Use an external 200A fuse, connect a source through RCA inputs, and verify that the connected subwoofers present no less than a 1-ohm final impedance.\u003c\/p\u003e","brand":"HIFONICS","offers":[{"title":"Default Title","offer_id":47997130834083,"sku":"BXX2000-1D","price":198.31,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/5416\/9507\/files\/710Ut4PssRL.jpg?v=1786819216","url":"https:\/\/nsiexport.com\/products\/hifonics-bxx2000-1d","provider":"NSI Export","version":"1.0","type":"link"}
