ROCKFORD FOSGATE (P3SD4-8) PUNCH 8" P3S SHALLOW 4-OHM DVC SUBWOOFER 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. 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. FEATURES: M-Roll Santoprene™ surround Diamond cut cast aluminum trim ring with optional grille Dual linear spider with embedded 16 AWG tinsel leads StampCast basket with integrated spider venting Anodized aluminum cone and dustcap Shallow Motor Assembly Optimized for both sealed and vented enclosures TECHNOLOGIES CEA-2031: Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. Stitched Tinsel Leads: Improved reliability and performance by reducing fatigue and possible shorting. Klippel Verified: Klippel is a speaker certification program allowing us to deliver the best possible subwoofers. 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. 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.
