It is intended for installations where factory or full-range speakers alone cannot reproduce the depth and impact of bass-heavy music. Because it is a component subwoofer, it requires a separate enclosure and external amplifier.\u003c\/p\u003e\u003cp\u003eThis model uses dual 4-ohm voice coils, giving installers wiring flexibility when matching the subwoofer to a compatible amplifier. Its published power handling is 1,500 watts RMS and 3,000 watts maximum. The large 15-inch format is suited to systems built around substantial bass output rather than compact-space installation.\u003c\/p\u003e\u003cp\u003eThe BRW15D4 is built around a 3-inch voice coil on a vented aluminum former. The vented former is designed to help exchange heat during operation, supporting more consistent performance when the subwoofer is driven for extended listening sessions. A vented high-energy motor assembly uses dual 70-ounce magnets.\u003c\/p\u003e\u003cp\u003eIts suspension system combines a pressure-treated, double-stitched ribbed foam surround with a dual poly-cotton spider. This arrangement is intended to help keep cone travel controlled and linear. Double centering in the spider assembly supports stable piston motion under power.\u003c\/p\u003e\u003cp\u003eA heavy-gauge aluminum die-cast basket provides the structural foundation for the woofer and includes rear venting. The powder-coated frame is designed for the demands of mobile-audio installation while helping airflow reach the motor area. Pair the BRW15D4 with a properly sized enclosure and an amplifier that is stable at the final impedance created by its dual voice coils.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e15-Inch Component Subwoofer:\u003c\/strong\u003e Provides dedicated low-frequency reproduction for a custom car-audio system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Offers wiring options for matching a compatible amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1,500-Watt RMS Handling:\u003c\/strong\u003e Supports sustained amplified bass output within its rated capability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-Inch Vented Aluminum Former:\u003c\/strong\u003e Helps manage 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\u003eDie-Cast Aluminum Basket:\u003c\/strong\u003e Provides a rigid, powder-coated mounting structure with rear venting.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe BRW15D4 uses a heavy-gauge, powder-coated aluminum die-cast basket, a vented motor structure, and a pressure-treated double-stitched ribbed foam surround.

Use an external amplifier and wire both dual 4-ohm voice coils according to the amplifier's supported load and the desired final impedance. Confirm enclosure dimensions, available mounting clearance, amplifier capability, and vehicle electrical capacity before installation.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631911460934,"sku":"BRW15D4","price":302.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/81tC4b4i3LL.jpg?v=1784387241","url":"https:\/\/audiowatt.store\/products\/hifonics-brw15d4-15-dual-4-ohm-car-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
