ROCKFORD FOSGATE P1S4-8 8" Punch P1 400 Watt 4-Ohm SVC Car Audio Subwoofer P1S48

The Rockford Fosgate P1S4-8 8" Punch P1 400 Watt 4-Ohm SVC Car Audio Subwoofer is built to give you the punch you desire, thanks to Kevlar fiber reinforced paper cones that deliver bass impact you can feel, and VAST technology that increases cone surface area up to 25%. This subwoofer uses an anodized aluminum voice coil former that provides superior heat dissipation (up to 100° at max power levels). The P1S4-8 has the capacity to handle power under continuous demand, conforming to CEA-2031 industry standards, and the stitched tinsel leads improve reliability and performance by reducing fatigue and possible shorting.

It also features: 10-gauge nickle plated push terminals, a diamond cut aluminum trim ring with optional grille, a dual liner spider with embedded 16-gauge tinsel leads, a high-temperature voice coil with spun-laced Nomex® reinforcement collar, a protective PVC textured magnet cover, a StampCast basket with integrated spider venting, an extended pole piece, and bumped vented backplate, a soft touch ABS tri trim ring, and is best suited for standard sealed and vented enclosures. Feel the impact with the Rockford Fosgate P1S4-8 Punch P1 Subwoofer!
