The Rockford Fosgate P3SD4-8 is an 8″ shallow mount subwoofer that 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.

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.

Main Features:

  • M-Roll Santoprene™ surround
  • Diamond cut cast aluminium trim ring with optional grille
  • Dual linear spider with embedded 16 AWG tinsel leads
  • StampCast basket with integrated spider venting
  • Anodised aluminium cone and dustcap
  • Shallow Motor Assembly
  • Optimised for both sealed and vented enclosures
  • CEA-2031 Compliant
