Its mono configuration concentrates amplification on low-frequency reproduction, making it suited to systems that need dedicated subwoofer power. The amplifier is stable to a 1-ohm load and provides onboard controls for setting it up to match the connected subwoofer and source unit.\u003c\/p\u003e\u003cp\u003eHifonics lists output of 1 x 2,000 watts at 1 ohm, 1 x 1,000 watts at 2 ohms, and 1 x 500 watts at 4 ohms. This gives installers flexibility when selecting a compatible subwoofer or wiring multiple subwoofers to a final impedance the amplifier supports. A variable input level control helps match the amplifier to the voltage of the source unit.\u003c\/p\u003e\u003cp\u003eThe A2000.1D uses Hifonics Super D-Class circuitry and Ultra-Fi MOSFET output devices. Its Twin Turbo Coil pulse-width-modulated power supply is designed to maintain voltage through the output stage. A heavy-duty aluminum-alloy heat sink helps move heat away from the amplifier components during use.\u003c\/p\u003e\u003cp\u003eFor bass tuning, the amplifier includes a variable low-pass crossover, subsonic filter, bass EQ, bass boost, and variable phase adjustment. These controls allow the installer to limit upper-frequency output, set low-frequency protection, and tailor bass response to the system. The included HFR-31 wired bass remote provides a convenient in-vehicle adjustment point.\u003c\/p\u003e\u003cp\u003eThis amplifier fits into an aftermarket subwoofer upgrade that uses a compatible source signal, correctly wired power connections, and a subwoofer load no lower than 1 ohm. It accepts speaker-level audio inputs as well as RCA signal connections. Nickel-plated terminals and angled connection access support an organized installation when adequate ventilation is provided.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono Subwoofer Design:\u003c\/strong\u003e One-channel architecture dedicated to subwoofer amplification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-Ohm Stability:\u003c\/strong\u003e Supports compatible subwoofer loads down to 1 ohm.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuper D-Class Circuitry:\u003c\/strong\u003e Efficient amplifier topology for dedicated bass systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Bass Tuning:\u003c\/strong\u003e Low-pass, subsonic, bass boost, and phase controls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHFR-31 Bass Remote:\u003c\/strong\u003e Wired remote provides accessible bass-level adjustment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Level Inputs:\u003c\/strong\u003e Allows integration with compatible speaker-level source signals.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe A2000.1D has a black finish, nickel-plated RCA connectors, nickel-plated high-temperature impact-resistant hex-screw terminals, and a heavy-duty aluminum-alloy heat sink. Hifonics also specifies surface-mount technology within the amplifier and LED diagnostics for overload and speaker-short protection. The listed amplifier weight is 8.8 lb, while the listed overall dimensions are 18.75 x 7.0 x 3.38 inches.\u003c\/p\u003e\u003cp\u003eMount the amplifier securely on a surface with ventilation and keep it protected from moisture and excessive heat. Use 4 AWG power and ground connections, 14 AWG speaker wire at the amplifier terminals, and an external 100A fuse as specified by Hifonics. Match the final subwoofer load to the amplifier, connect the source through RCA or speaker-level inputs, and set gain and crossover controls carefully during system setup.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631903236166,"sku":"A2000-1D","price":386.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71yiUFnm1TL.jpg?v=1784385859","url":"https:\/\/audiowatt.store\/products\/hifonics-a2000-1d-2000w-monoblock-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
