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.

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.
