Rockford Fosgate P3S 8" shallow mount subwoofer delivers “Punch” even when depth is limited. The P3SD4-8 features Dual 4-Ohm voice coils for wiring flexibility and 150 Watts RMS power handling.
Overview
The Rockford Fosgate P3S 8" shallow mount subwoofer delivers Punch, even in depth limited situations. Rockford Fosgate understands all vehicles are not the same, because some cannot accommodate deep subwoofers. In the past, that meant no Bass. Not anymore! Now even depth challenged vehicles can have REAL Bass and the Dual Voice Coil allow configurations for every application. Shallow woofers are specifically designed for spaces where a traditional woofer cannot be used.

Technologies
Klippel Verified
Klippel is a speaker certification program allowing us to deliver the best possible subwoofers.
CEA-2031
Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards.
Anodized Aluminum Voice Coil Former
Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide superior heat dissipation (up to 100° at full power levels). Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions.
Stitched Tinsel Leads
Improved reliability and performance by reducing fatigue and possible shorting.
VAST Surround - Subs
The Vertical Attach Surround Technique significantly increases a subwoofer's effective radiating cone area up to 25%.
FlexFit Basket - Subwoofer
The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position.
