Rockford Fosgate P3S-1X12 Punch Single P3 12" Shallow Loaded Enclosure

Rockford Fosgate P3S-1X12 Punch P3 Shallow 12" Sealed Loaded Enclosure 400 Watts, Slim Fit, Serious Output

Product Overview

The Rockford Fosgate P3S-1X12 is a factory-loaded sealed enclosure housing a single Punch P3S shallow 12" subwoofer (P3SD2-12) rated at 400 Watts RMS and 800 Watts peak. Internally pre-wired to a 1-ohm load, it is designed to be driven hard by a compatible high-output mono amplifier delivering genuine P3-level bass performance from a slim-line wedge enclosure purpose-built for behind-seat and under-seat truck and ute installations where depth is the critical constraint.

The P3S-1X12 steps up significantly from the T1S-1X12 in both power handling and driver pedigree, housing the Punch P3S shallow driver in a computer-optimised sealed enclosure constructed from 5/8" MDF. High-density carpet with a stitched Diamond-R logo, Rockford Fosgate speaker cable internal wiring, and 10 AWG quick-release compression input terminals complete a loaded enclosure that looks and performs as a premium, purpose-built solution. A trim ring is included, ready to accept an optional stamped mesh grille insert for a finished, professional appearance.

Features & Benefits

• 400W RMS / 800W peak power handling: The P3S-1X12 is built for serious amplifier output. Pre-wired to 1 ohm, it is ready to extract maximum power from a compatible high-output mono amplifier delivering P3-level bass performance that goes well beyond entry-level slim enclosure solutions.
• Punch P3S shallow 12" driver (P3SD2-12): The P3S series shallow driver is purpose-engineered for reduced mounting depth without the performance compromises of a standard driver in an undersized box. The result is deeper, tighter bass from a slim profile than a generic shallow woofer can achieve.
• Pre-wired to 1 ohm: Factory internal wiring to 1 ohm maximises power delivery from compatible mono amplifiers. No internal wiring configuration required connect your amplifier to the 10 AWG input terminals and go.
• Computer-optimised sealed enclosure design: The enclosure volume and geometry are calculated specifically for the P3S driver, ensuring the sealed alignment produces the accurate, punchy bass response the P3 series is built for not a generic box tuned to approximate specifications.
• Slim-line wedge profile: The wedge shape (D1: 13.46 cm / D2: 8.38 cm) maximises internal volume within the minimum possible height, fitting behind and under seats in utes, trucks, and dual-cab vehicles where standard enclosure depth is not available.
• 5/8" MDF construction: Rigid enclosure walls minimise flex, resonance, and panel vibration at the high output levels the P3S-1X12 is designed to handle. Essential for accurate bass reproduction at 400W RMS continuous input.
• High-density carpet with stitched Diamond-R logo: Premium factory finish that integrates cleanly into vehicle interiors. The high-density carpet is more durable and resistant to wear than standard carpet finishes, suited to daily ute and truck cab use.
• Rockford Fosgate speaker cable internal wiring: Factory-installed Rockford Fosgate cable ensures signal integrity from the input terminals to the driver. No compromises from generic or undersized internal wiring at the 1-ohm, high-current load this enclosure operates at.
• 10 AWG quick-release compression input terminals: Heavier gauge than the 12 AWG terminals found on lower-spec loaded enclosures, appropriate for the higher current demands of a 400W RMS, 1-ohm system. Tool-free quick-release operation for clean installation and removal.
• Included trim ring with optional grille compatibility: The trim ring ships in the box and is ready to accept a separately available stamped mesh grille insert for a factory-finished, professional appearance once installed.

Frequently Asked Questions

What amplifier does the P3S-1X12 require? The P3S-1X12 is pre-wired to 1 ohm and handles 400W RMS. A mono amplifier stable at 1 ohm and rated at or near 400W RMS is recommended such as a compatible Rockford Fosgate Power or Punch mono amplifier. Do not exceed 800W peak input.

How does the P3S-1X12 compare to the T1S-1X12? Both are slim sealed loaded enclosures pre-wired to 1 ohm for behind-seat ute and truck installs. The P3S-1X12 steps up with a higher-pedigree Punch P3S shallow driver, 400W RMS power handling (vs 600W for the T1S), and heavier 10 AWG input terminals confirm the T1S-1X12 power spec with your supplier when comparing the two.

Will the P3S-1X12 fit behind the seat of my ute or dual-cab? The P3S-1X12 uses a wedge profile measuring 34.29 cm high, 69.59 cm wide, and 13.46 to 8.38 cm deep. Measure your available behind-seat or under-seat space carefully against these dimensions before purchase, as clearance varies between vehicle models.

Is a grille included with the P3S-1X12? A trim ring is included, ready to accept an optional stamped mesh grille insert. The grille itself is sold separately confirm the compatible part number with your supplier.

What does the computer-optimised design mean for bass performance? It means the enclosure volume and geometry are calculated specifically for the P3S shallow driver rather than being a generic box. This results in a sealed alignment that accurately matches the driver's parameters, producing tighter, deeper, and more accurate bass than a non-optimised enclosure of similar size.
