5515-44 15-Inch Car Subwoofer + 15 Sq Ft Sound Deadener

The main event is a 15-inch car subwoofer built for high-output bass, with 400 W RMS and 800 W peak power handling, dual 4-ohm voice coils, and a 19 Hz to 130 Hz frequency response. It suits a custom car-audio setup where strong low-frequency output matters. Spider Plateau Venting directs cool air toward the voice coil, while the radial-ribbed t-yoke helps manage heat. The Inverted Apex Surround increases cone surface area, and progressive suspension controls excursion to reduce distortion at higher output. A 15 sq ft, 3-in-1 sound-deadening pack comes as a bonus, with 14 sheets of butyl rubber, acoustic foam, and aluminum plus a wood-and-steel roller. Apply the sheets to vehicle doors, floors, or trunk areas to reduce noise and sound leakage. Together, the subwoofer and included treatment give installers bass hardware and material for a quieter listening space in one package.
