12" 4-Ohm DVC Punch P2 Subwoofer 400W RMS, Kevlar Cone, VAST, Dual Spider, Diamond-Cut Cast Aluminium Trim Ring, Extended Pole Piece.

Product Overview

The Rockford Fosgate Punch P2D4-12 is a 12" 4-Ohm Dual Voice Coil (DVC) subwoofer rated at 400W RMS the 4-Ohm variant of the 12" Punch P2 platform. Identical construction to the P2D2-12 with the sole difference being 4-Ohm voice coil impedance per coil, providing wiring options of 2-Ohm (parallel), 8-Ohm (series), or 4-Ohm per coil for bi-amplification broader amplifier compatibility than the 2-Ohm variant without the 1-Ohm parallel concern. Optimised for sealed and vented enclosures. Sold as an individual unit.

All confirmed Punch P2 construction applies: Kevlar fibre-reinforced paper cone, VAST surround (up to 25% increased cone area), high-temperature voice coil with spun-laced Nomex® reinforcement collar, dual linear spider with embedded 16 AWG tinsel leads, extended pole piece with bumped vented backplate, StampCast basket with integrated spider venting, diamond-cut cast aluminium trim ring with grille provision, and protective PVC textured magnet cover.

Features & Benefits

  • 4-Ohm DVC — Broad Amplifier Compatibility, No 1-Ohm Requirement:
    • 2-Ohm (parallel): Most common — compatible with 2-Ohm mono amplifiers
    • 8-Ohm (series): For amplifiers with higher minimum impedance
    • 4-Ohm per coil (biamp): Separate amplifier channels
  • 400W RMS — Confirmed 400W RMS — same as P2D2-12. Requires an amplifier rated at 400W RMS at the selected impedance.
  • 12" Cone — Greater air movement and lower frequency extension than the 10" P2 models.
  • Dual Linear Spider — Improved compliance linearity and cone control at high excursion.
  • Kevlar Fibre-Reinforced Paper Cone with VAST — Stiffness and breakup resistance plus up to 25% increased effective cone area.
  • Nomex® Voice Coil Collar — Thermal and mechanical reinforcement at 400W sustained.
  • Extended Pole Piece and Bumped Vented Backplate — Increased Xmax; air spring prevention.
  • Diamond-Cut Cast Aluminium Trim Ring — Premium machined aluminium finish with grille provision.
  • StampCast Basket with Integrated Spider Venting — Motor cooling during operation.

Frequently Asked Questions

What is the difference between P2D4-12 and P2D2-12?

Both are identical 12" Punch P2 subwoofers with the same 400W RMS and construction. The sole difference is impedance: P2D4-12 is 4-Ohm per coil (2-Ohm parallel / 8-Ohm series), P2D2-12 is 2-Ohm per coil (1-Ohm parallel / 4-Ohm series). The 4-Ohm DVC avoids the 1-Ohm parallel requirement and is more broadly compatible with most mono amplifiers.

What amplifier power is appropriate?

400W RMS at the selected wiring impedance. Confirm the amplifier's RMS output at 2-Ohm (parallel) or 4-Ohm before purchasing.

What enclosure volume is recommended?

Not confirmed in the supplier data. Pull the official Rockford Fosgate P2D4-12 datasheet for sealed and vented volume recommendations.

Is a grille available?

The diamond-cut cast aluminium trim ring accommodates an optional grille insert. Confirm the compatible SKU with Rockford Fosgate.

What terminal type does the P2D4-12 use?

The features list states "nickel plated push terminals." The P2D4-10 spec table indicates "compression terminals" — a conflict present across the P2 range. Confirm with Rockford Fosgate.
