It is intended for listeners whose factory or full-range speakers do not provide the depth and impact they want from bass-heavy music. As a component subwoofer, it requires a separate enclosure and external amplifier.\u003c\/p\u003e\u003cp\u003eThis Brutus-series model uses dual 4-ohm voice coils, giving system builders wiring flexibility when selecting a compatible mono or multi-subwoofer amplifier setup. Its listed maximum output is 2,000 watts. The dual-coil configuration should be matched carefully to the amplifier's supported final impedance.\u003c\/p\u003e\u003cp\u003eThe BRW12D4 uses a vented aluminum former around its 3-inch voice coil. This arrangement is designed to promote heat exchange around the coil during operation. Managing heat is important in a subwoofer system because it supports more consistent operation when the driver is used at higher output levels.\u003c\/p\u003e\u003cp\u003eA dual poly-cotton spider with double centering works with the pressure-treated, double-stitched ribbed foam surround to support controlled cone movement. These suspension components are designed to help keep the woofer's piston motion linear. The result is a construction approach focused on stable excursion and reduced mechanical stress.\u003c\/p\u003e\u003cp\u003eFor an upgrade path, the BRW12D4 fits custom systems built around a dedicated subwoofer enclosure and properly matched external amplification. Its heavy-gauge, powder-coated aluminum die-cast basket and vented motor assembly are intended for the demands of a purpose-built bass system. Confirm enclosure dimensions, amplifier capability, wiring configuration, and vehicle space before installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch Component Subwoofer:\u003c\/strong\u003e Adds dedicated bass reproduction to a custom car-audio system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Provides wiring options for compatible amplifier configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2,000-Watt Maximum Output:\u003c\/strong\u003e Supports use in higher-output bass system designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Inch Vented Aluminum Former:\u003c\/strong\u003e Helps exchange heat around the voice-coil assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 70-Ounce Magnets:\u003c\/strong\u003e Forms part of the vented high-energy motor assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Poly-Cotton Spiders:\u003c\/strong\u003e Supports controlled cone movement with double centering.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe BRW12D4 is built on a heavy-gauge, powder-coated aluminum die-cast basket with back venting.

These materials and ventilation features support the driver structure and thermal management.\u003c\/p\u003e\u003cp\u003eInstall this component subwoofer in a suitable subwoofer enclosure and power it with an external amplifier. Wire both 4-ohm voice coils according to the amplifier's approved load range, and use an enclosure that physically accommodates the woofer and motor structure. Professional installation or careful verification of polarity, final impedance, enclosure fit, and amplifier settings is recommended.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631910838342,"sku":"BRW12D4","price":264.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/818HF4DutDL_c5aab577-a304-433d-8473-f40eb9e7e660.jpg?v=1784387140","url":"https:\/\/audiowatt.store\/products\/hifonics-brw12d4-12-dual-4-ohm-car-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
