It is intended for listeners who want more bass depth and impact than typical full-range car speakers can provide. Because it is a component subwoofer, it requires a separate enclosure and an external amplifier.\u003c\/p\u003e\u003cp\u003eThis Brutus-series model uses a dual 4-ohm voice-coil configuration for system-design flexibility. Its listed 1600-watt power handling supports use in higher-output bass systems when paired with an appropriately matched amplifier. The dual-coil layout lets an installer select a final wiring load that is compatible with the amplifier being used.\u003c\/p\u003e\u003cp\u003eThe BRW10D4 is engineered around a vented aluminum voice-coil former and a 3-inch voice coil. The vented former is designed to exchange heat during operation, helping manage heat buildup at the voice coil. This construction supports sustained bass playback while prioritizing controlled piston movement.\u003c\/p\u003e\u003cp\u003eA pressure-treated, double-stitched ribbed foam surround works with a dual poly-cotton spider assembly. The double-centered spider design is intended to help keep cone travel linear under power. Together, these parts support the subwoofer's moving assembly during bass-heavy listening.\u003c\/p\u003e\u003cp\u003eFor a complete upgrade, install the BRW10D4 in a correctly built subwoofer enclosure and power it with a compatible external amplifier. Its heavy-duty basket and vented motor structure make it suited to custom trunk, hatch, or cargo-area bass systems. Select the enclosure, amplifier output, and wiring configuration as a matched system rather than treating the subwoofer as a direct replacement for a full-range speaker.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-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 flexibility for compatible amplifier loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1600-Watt Listed Power Handling:\u003c\/strong\u003e Supports use in higher-output amplified bass systems.\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 high-energy motor assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual Poly-Cotton Spider:\u003c\/strong\u003e Helps support centered, controlled cone movement.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe BRW10D4 uses a heavy-gauge, powder-coated aluminum die-cast basket with back venting. Its moving assembly includes a pressure-treated double-stitched ribbed foam surround, dual poly-cotton spider, vented aluminum former, and dual 70-ounce magnets. These components are designed for a durable installation in a car-audio subwoofer enclosure.\u003c\/p\u003e\u003cp\u003eThis is a passive component subwoofer, so an enclosure and external amplifier are required for operation. Wire its dual 4-ohm coils according to the amplifier's approved impedance capability, and use an enclosure designed for the selected system goals. Confirm mounting clearance, enclosure volume, and amplifier compatibility before installation.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631908511814,"sku":"BRW10D4","price":202.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/818HF4DutDL.jpg?v=1784386751","url":"https:\/\/audiowatt.store\/products\/hifonics-brw10d4-10-dual-4-ohm-car-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
