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.

*Installation Available on everything we sell. Parts and extensive work extra.

Standout performance

Rockford Fosgate showcases their fanatical commitment to sonic excellence in the Punch Series of speakers, amps, and subs. If you like to listen to potent, powerful music — and feel it too — Punch components will give you impressive sound that’ll stand out in a crowd.


Designed for deeper, louder bass

Rockford Fosgate designed the P3D4-12 12″ subwoofer to stay strong even when the bass gets hot. This Punch P3 sub features a rigid anodized aluminum cone that holds its shape through heavy play, while staying light and responsive. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass.

Heat-sink cone

The aluminum cone acts as a giant heat sink, directing heat away from the copper-clad aluminum voice coils. Special venting keeps the voice coils cool, so you get incredibly consistent bass performance over time. This P3 sub features an extended pole piece and bumped backplate that leaves more room for heavy excursion, so it’ll hit deeper lows without “bottoming out.”

The dual 4-ohm voice coils allow you to wire the sub for 2-ohm impedance to get maximum power output, or for 8-ohm impedance if you’re using multiple subs. The P3D4-12 sub works equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.
