You can wire both coils in parallel for a 1 ohm final load, or in series for a 4 ohm final load. Make sure your amplifier is stable at the load you choose before wiring it up.\u003cbr\u003e\u003cbr\u003e\nWith 20 mm of Xmax, a 30 Hz Fs and a Vas of 75.50 L (about 2.67 cubic feet), this sub is made to move a lot of air. Plan your build around its size, though. It needs a 16.71\" cutout and 12.13\" of mounting depth, so check your enclosure’s internal depth behind the baffle before you order.\u003cbr\u003e\u003cbr\u003e\nIf you’re building a big single 18 setup or stepping up to a multi sub wall, the Doomsday 18 D2 has the power handling and excursion to back it up.\u003c\/p\u003e\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cbr\u003e\n  \u003cli\u003eDual 2 ohm voice coils: wire to 1 ohm (parallel) or 4 ohm (series)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eCutout diameter: 16.71\" (424.5 mm), measured as the hole size cut in the baffle\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMounting depth: 12.13\" (308 mm), measured from the mounting surface to the back of the motor\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eVas of 75.50 L (about 2.67 cu ft) means it’s a large air space driver, so it isn’t suited for small shallow boxes\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eGross weight: 89.29 lb (40.5 kg); make sure your baffle and enclosure bracing can support it\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cbr\u003e\n  \u003cli\u003eModel: Doomsday 18 D2\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eSize: 18\"\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eType: Passive Subwoofer\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eRMS Power: 3,500W\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMax Power: 7,000W\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eImpedance: Dual 2 Ohm (2+2)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eVoice Coil Size: 4.00\"\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eVoice Coil Wire: Aluminum\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eCone Material: Pressed Paper\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eSurround Material: Foam\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMagnet Type: Ferrite\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eFrame: Aluminum\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eSPL: 87.90 dB\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eFs: 30.00 Hz\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eQts: 0.49\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eBL: 27.40\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eVas: 75.50 L\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eXmax: 20.00 mm (0.79\")\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eMounting Depth: 12.13\" (308.0 mm)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eCut-Out Diameter: 16.71\" (424.5 mm)\u003c\/li\u003e\n\u003cbr\u003e\n  \u003cli\u003eGross Weight: 89.29 lb (40.5 kg)\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\n\u003cp\u003eA big, heavy 18 with real excursion, ready for builds that need more than a typical daily sub.\u003c\/p\u003e","brand":"Avatar","offers":[{"title":"Default Title","offer_id":68065436565752,"sku":"AT-DOOMSDAY-18-D2","price":849.9,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0029\/9384\/8365\/files\/3aee95139794bad21634abb4cdca23003f5318ee2ecf17b5856f79af8c180cb4_62d211bd-921b-41da-ae64-c861e1ef1a83.jpg?v=1794409089","url":"https:\/\/bigjeffaudio.com\/products\/avatar-18-car-subwoofer-3500w-rms-dual-2-ohm-4-voice-coil-doomsday-18-d2","provider":"Big Jeff Online Inc","version":"1.0","type":"link"}
