Frequently Bought Together


The Unit Includes: 8 inch shallow subwoofer driver, Diamond cut cast aluminum trim ring, and Instruction manual.

Rockford Fosgate Punch Stage 3

Rockford Fosgate has taken their P3 shallow subwoofers to the highest level. The Stage 3 shallow subwoofers offer deep bass and unparallelled quality with the thinnest profile. These subwoofers accept up to 400 watts of power RMS, the 8" Anodized aluminum cone and dustcap provides excellent sound quality with minimal distortion. The shallow motor assembly has a new dual linear spider with embedded tinsel leads that keeps the cone in perfect alignment and allows for high excursion levels.

Anodized Aluminum Voice Coil Former

Heat is the #1 concern with subwoofers, dissipating the heat is the challenge. Rockford Fosgate P3S shallow subwoofers use anodized aluminum voice coil formers that provide excellent heat dissipation. Aluminum is an excellent heat-sink and allows the Rockford P3SD4-8 subwoofer to stay cool during high volume conditions. The high-temperature voicecoil is designed with a Nomex reinforcement collar and meant to handle even the loudest volume levels.

CEA-2031 Compliant

The Rockford Fosgate P3SD2-8 conforms to CEA-2031 industry standards. This means your 8" subwoofer has the capacity to handle power under continuous demand, not instantaneous power handling, that over time can damage voice coils.

VAST Surround

V.A.S.T. Stands for Vertical Attach Surround Technique, this technology significantly increases a subwoofer's effective radiating cone area up to 25%. This design allows for more output from an equivalent speaker size without increasing installation challenges. This is done by eliminating the large flat glue surface area (the landing), which allows the surround to be shifted for increased cone area. This improves efficiency and output dramatically.

Stitched Tinsel Leads

To reduce fatigue and prevent catastrophic damage from shorts the P3SD4-8 8" subwoofer uses stitched tinsel leads. By using this technology fatigue on the leads is dissipated over a greater area which improves the life of the subwoofer and contributes to a robust design.
