Compact Frame, Full Throttle Bass Output

If you are working with limited space but still want serious low-frequency impact, the Rockford Fosgate Punch P3SD4-8 shallow subwoofer is built to deliver exactly that balance. Its reduced-depth motor architecture lets it fit into tight enclosures and compact vehicle locations without losing punch or clarity. Even in a small footprint, it produces strong, controlled bass that feels tight and responsive, making it a perfect match for space-conscious car audio builds.

Wiring Freedom Built for Real System Tuning

This subwoofer gives you flexible control over your setup thanks to its dual 4-ohm voice coil design. You can wire it for 2-ohm performance when you want more output or go to 8-ohm for different amplifier matching strategies. That kind of versatility makes it easy to integrate into a wide range of systems without compromise. With CEA-2031 certified power handling, it is designed to stay consistent under real-world listening conditions, even when pushed hard for long periods.

Small Size Engineering With Big Bass Character

The P3SD4-8 uses expanded acoustic output technology with a VAST surround design that increases cone efficiency without increasing overall size. That means more bass output from an 8 inch shallow sub that is still easy to install in compact enclosures. It works well in both sealed setups for tight, accurate bass and ported designs for stronger output and deeper impact. Add in the FlexFit basket for easier alignment and the reinforced aluminum trim ring for stability and clean finishing, and you get a subwoofer that is small in size but serious in performance.

  • Placed it in the stock JBL box on my TUndra and it fits fine. Really an easy installation. Sound is much way better than the stock sub, and it also hits harder. Its just 150 watts but its loud enough to make the sound inside your truck boomy.
