{"product_id":"hifonics-zg12d4","title":"Hifonics ZG12D4 12\" Dual 4-Ohm Car Subwoofer","description":"\u003cp\u003eThe Hifonics ZG12D4 is a 12-inch component car subwoofer designed to add dedicated low-frequency output to a vehicle audio system. It handles 400 watts RMS and up to 800 watts maximum power. Because it is a non-enclosed, non-powered driver, it requires a separate amplifier and subwoofer enclosure.\u003c\/p\u003e\u003cp\u003eThis model is intended for listeners building or upgrading a bass system around a single 12-inch woofer. Its dual 4-ohm voice-coil configuration provides wiring flexibility for matching a compatible mono or multi-channel amplifier. The design can be wired for a 2-ohm or 8-ohm final load when used as one subwoofer.\u003c\/p\u003e\u003cp\u003eThe ZG12D4 uses a pressure-treated blue foam surround and Hifonics cotton spider to support controlled cone movement. Its thermal-formed polypropylene cone has a molded Zeus symbol and six-spoke design. These components are paired with a vented aluminum voice-coil former to help manage heat during operation.\u003c\/p\u003e\u003cp\u003eA heavy-gauge, powder-coated stamped-steel basket forms the foundation for the motor and moving assembly. Through-the-frame venting with a mesh grille and a vented high-energy motor support airflow around the speaker structure. The rear motor cover helps protect the back of the subwoofer.\u003c\/p\u003e\u003cp\u003eThe ZG12D4 is suited to small sealed enclosures or medium-to-large vented enclosures, with ported designs identified as an ideal application. It has a 10-inch cutout requirement and 5.4-inch mounting depth, so enclosure dimensions should be checked before installation. Pair it with an amplifier selected and set appropriately for its 400-watt RMS rating and final wired impedance.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e400-Watt RMS Handling:\u003c\/strong\u003e Supports amplifier matching based on continuous power capability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 4-Ohm Voice Coils:\u003c\/strong\u003e Allows series or parallel wiring flexibility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12-Inch Woofer:\u003c\/strong\u003e Provides dedicated bass reproduction for vehicle audio systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVented Aluminum Former:\u003c\/strong\u003e Helps move heat away from the voice coil.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSteel Basket:\u003c\/strong\u003e Powder-coated stamped-steel construction supports the motor assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorted-Enclosure Ready:\u003c\/strong\u003e Designed for medium-to-large vented enclosure applications.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe subwoofer combines a thermal-formed polypropylene cone, pressure-treated blue foam surround, cotton spider, and a heavy-duty powder-coated steel basket. Its 2-inch voice coil uses a vented aluminum former, while through-frame venting and a vented motor assembly promote airflow. The motor uses 37-ounce magnets, and a rear motor cover protects the back of the assembly.\u003c\/p\u003e\u003cp\u003eMount the ZG12D4 in an enclosure with at least a 10-inch cutout and 5.4 inches of mounting depth. Use the spade-style terminals to connect both 4-ohm voice coils according to the amplifier's supported load: parallel wiring presents 2 ohms and series wiring presents 8 ohms. Select a properly configured external amplifier, secure the driver to a rigid enclosure, and ensure the enclosure type suits the intended installation.\u003c\/p\u003e","brand":"HIFONICS","offers":[{"title":"Default Title","offer_id":45776292577471,"sku":"ZG12D4","price":32.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/6252\/4351\/files\/61UrDRp9-IL.jpg?v=1782490308","url":"https:\/\/nsidistributor.com\/products\/hifonics-zg12d4","provider":"NSI Audio Distributing","version":"1.0","type":"link"}
