Rockford Fosgate Punch P3S Series 12" Shallow Mount Subwoofer

The Rockford Fosgate P3S 12" shallow mount subwoofer is engineered to deliver real bass in depth-limited installations, using a dual voice coil design for flexible impedance and wiring options. Its shallow geometry is paired with a rugged build to keep performance intact when space is at a premium.

• Shallow mounting depth: 3.65 in mounting depth, designed for tight dash, kick panel, or rear-shelf installations where standard woofers won’t fit.
• Dual voice coil: Dual 2.5" voice coils provide wiring and impedance flexibility, with configurations available in Dual 2-Ohm or Dual 4-Ohm setups to match amplifier strategy.
• Power handling: 400 Watts RMS real-world continuous power with up to 800 Watts peak, offering headroom for clean, dynamic bass with suitable amplification.
• Enclosure compatibility: Optimized for both sealed (1.0 cu ft) and vented (1.25 cu ft) enclosures, giving you predictable low-end output in compact boxes. Vas is ~35.3 L, Sd ~500 cm².
• Construction and cooling: StampCast basket with integrated spider venting, Diamond-cut cast aluminum trim ring, and vented motor design for durability and effective cooling in high-excursion use.
• Surround and cone: M-Roll Santoprene surround with an anodized aluminum cone and dustcap for stiffness, stiffness retention, and resistance to corrosion.
• Performance and tuning: Sensitivity 85 dB @ 1W/1m; Fs ~34–35 Hz; Xmax ~8.1–8.4 mm; Qts ~0.67–0.72; Qes ~0.75–0.83; Qms ~5.70–6.60, indicating solid musical bass response with controlled transient behavior.
• Physical and electrical: 12" woofer with a 2.5" voice coil diameter, 11.22" cutout, mounting depth 3.65", magnet weight ~51 oz (1.45 kg), and Re ~3.40 Ω (typical) with Le around 2.8–4.4 mH depending on variant.
• Compliance: CEA-2031 compliant, aligning with industry standards for performance and measurement practices.

Benefits: In a real car audio build, this sub shines in shallow enclosures behind dashboards, under seats, or in tight hatch spaces where deep subs simply can't fit. The dual-voice-coil design provides wiring flexibility to match a variety of amplifiers and impedance strategies, while the enclosure tuning options (sealed or vented) let you tailor bass extension and punch to your vehicle. The robust mechanical structure, combined with a high-excursion surround and aluminum cone, supports durable performance in demanding installations without sacrificing low-end output.)
