ALPINE X-W12D4 12″ 900 Watt RMS Car Audio Subwoofer DVC Dual-4ohm X-Series Sub. Alpine ID Sound Quality. 900W RMS, making it a perfect match for the X-Series X-A90M 900W mono amplifier. 24mm linear Xmax (1 way), 48 mm peak to peak. Dual spiders for precision control over the large dynamic range. Dual shorting rings for strong motor control ensuring low THD and tight bass
Center pole radial heat sink which wicks heat away from the voice coil and transfers it outside the motor, for long term high output. The biggest HAMR surround yet, for linear cone movement throughout its large range of excursion. Light but rigid pulp/mica cone which allows for highly accurate bass with great natural tone. Twist-lock Trim ring with full mesh grill included. Frequency Response: 22Hz-200Hz. Mounting Depth: 7 1/4″. Cutout Diameter: 111/16″. Includes: Amplifier. Bass Remote
