Rockford Fosgate P3D4-12 – The Iconic 12" P3 Sub That Brings the Thunder
The Rockford Fosgate P3D4-12 is the subwoofer people mean when they talk about real Rockford bass. This 12" beast delivers deep, tight, earth-shaking low end with the kind of authority that turns every song into an experience.
Its dual 4-ohm voice coils, high-excursion design, and Rockford’s signature VAST™ surround technology mean more output, more accuracy, and more impact in every beat. Whether you’re chasing clean musical bass or full-on window-flexing power, the P3D4-12 stays smooth, controlled, and brutally strong.
Put it in a sealed box for tight punch or a ported box for maximum slam — either way, it simply performs.
Perfect for: Drivers who want a legendary 12" sub that hits hard, sounds clean, and continues Rockford’s tradition of chest-pounding bass.
