Both versions use a ferrite motor, 2-inch voice coil and a 900-watt manufacturer rating; the real choice on this page is the dual-voice-coil impedance that best fits the amplifier and final wiring load.\u003c\/p\u003e\u003ch3\u003eChoose the Right Voice Coil\u003c\/h3\u003e\u003ch4\u003eDual 2 Ohm — C8A900SW-22\u003c\/h4\u003e\u003cp\u003eTwo 2-ohm voice coils give the installer different series\/parallel wiring options than the dual-4 version. Choose this model only after working backward from the amplifier's intended final load and the number of subwoofers in the system.\u003c\/p\u003e\u003ch4\u003eDual 4 Ohm — C8A900SW-44\u003c\/h4\u003e\u003cp\u003eTwo 4-ohm voice coils provide a different set of final-load options and can be the better fit in multi-subwoofer systems or with amplifiers that need a higher resulting impedance.\u003c\/p\u003e\u003ch3\u003eWhy These Are One Product\u003c\/h3\u003e\u003cp\u003eThe C8A900SW-22 and C8A900SW-44 are the same 8-inch Americano subwoofer platform with the same 900-watt rating and 2-inch voice coil size. Splitting them into separate products adds clutter without helping the customer; voice-coil configuration is the meaningful selector.\u003c\/p\u003e\u003ch3\u003eSystem Planning Matters\u003c\/h3\u003e\u003cp\u003eAn 8-inch sub can save space, but box design, available airspace, port area, tuning, amplifier power and electrical capacity still determine the result. Do not choose the dual-2 or dual-4 version by price—they are the same price. Choose it by the final impedance your amplifier needs to see.\u003c\/p\u003e\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConfirm cutout diameter, overall frame diameter, mounting depth and enclosure clearance before ordering.\u003c\/li\u003e\n\u003cli\u003ePlan the final impedance using the exact number of subwoofers and both voice coils on every driver.\u003c\/li\u003e\n\u003cli\u003eUse an enclosure appropriate for the specific vehicle, target bandwidth and output goal.\u003c\/li\u003e\n\u003cli\u003eSet amplifier gain and filtering from measured system limits rather than the wattage number alone.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eIncluded:\u003c\/strong\u003e one selected Ciare Americano C8A900SW subwoofer.
