7515-22 + 50-25 Subwoofer and Sound Deadening Kit

Build a more controlled car-audio setup with a 15-inch dual 2-ohm subwoofer and 50 square feet of sound-deadening material in one package. The 7515-22 handles 750 W RMS and 1,500 W peak, with a recommended amplifier range of 375 to 750 W RMS. Its inverted apex surround increases surface area and excursion, while spider plateau venting directs cool air toward the voice coil. A glass-fiber cone, progressive suspension and cast-aluminum basket support sensitivity, excursion control and reduced resonance.

The 50-25 kit adds twenty 20-by-18-inch sheets of 100-mil, 2.5 mm butyl material with aluminum coating and pressure-activated adhesive, covering 50 square feet. Apply it to vehicle panels to reduce rattles, vibration, and engine or exhaust noise while helping bass clarity. The embossed installation marker changes from hexagon to flat when pressed into place, and the included wood-and-steel roller helps seat the sheets. The kit is also listed for boats, UTVs, ATVs, studios, and home theater rooms. Sheets ship flat, not folded or rolled.
