Designed With Precision and Durability in Mind
The Rockford Fosgate P2D4-12 is a powerful 12-inch subwoofer with deep, punchy bass and exceptional performance. Designed with precision and durability in mind, this subwoofer is a popular choice among car audio enthusiasts looking to enhance their sound system.
Compatibility With Various Amplifiers
The P2D4-12 features a dual 4-ohm voice coil configuration, allowing for versatile wiring options and compatibility with various amplifiers. Its cone is constructed from anodized aluminum, which is lightweight yet rigid, enabling it to reproduce low frequencies accurately and efficiently.
Handle High Power Levels
With a peak power handling of 800 watts and an RMS power rating of 400 watts, the P2D4-12 can handle high power levels, resulting in an impactful bass response. It utilizes Rockford Fosgate's proprietary Vertical Attach Surround Technique (VAST) to increase cone area, improving overall sound output.
Easy Installation and Compatibility
The subwoofer incorporates an innovative Flex Fit basket design, which ensures easy installation and compatibility with a wide range of vehicles. Additionally, its stitched tinsel leads enhance reliability and provide increased durability.

Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 1.02 cubic feet (from 0.7 to 1.8 cubic feet is acceptable). Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.
Ported Box: Rockford recommends a ported enclosure with an internal volume of 1.79 cubic feet using one 4" diameter x 10" long port; this yields a tuning frequency of 40 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of very low frequency output (below 34 Hz).
Overview: The Rockford Fosgate Punch P2D4-12 is a 12-inch subwoofer with dual 4Ω voice coils. The sub features a StampCast steel frame, quick-release compression terminals, a Kevlar fiber reinforced paper cone, and Santoprene surround. An anodized aluminum voice coil former and spider venting help keep the subwoofer cool.
Dual 4Ω Voice Coils: The dual 4Ω voice coils offer wiring flexibility; when wired in parallel the woofer presents a 2Ω load, when wired in series the woofer presents an 8Ω mono load.
Steel Basket: The P2D4-12 subwoofer features a StampCast steel basket for added rigidity.
Compression Terminals: The P2D4-12 features spring post terminals which accommodate speaker wire up to 10 gauge.
CEA-2031 Compliant: Power handling on the P2D4-12 subwoofer conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle power under continuous demand, not instantaneous power handling, that over time, can damage voice coils.
FlexFit Basket: The Flex Fit frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.
Trim Ring: To improve the cosmetic look, a decorative trim ring is included that mounts over the flange of the woofer. When using the cast aluminum trim ring the woofer is first mounted with four screws, then the ring is placed on top of the woofer, aligning the final four holes of the woofer with ring. The other four screws are used for these holes to mount the ring and woofer to the enclosure. Without the trim ring the mounting height of the woofer is just over 7/8 of an inch, with the trim ring it's approximately 1-1/16 inches. The diameter of the trim ring is 13-5/16 inches.

Still kinda new to having dual voice coils but after getting that sorted out these subs are absolutely amazing. I replaced my old R1 10s with these and I just can't say enough about how they sound besides absolutely amazing.
I have 2 12's fosgate p2's hooked up to 1800 watt kenwood class d in my 89 prelude its whams so hard i have to hold my breath sometimes because it's to hard to breath definitly gotta get 2 p2 stage 2 fosgates 12's there worth the money.
I bought these from this website and they are well worth the money. They were at my door in five days with the free shipping. I built a sealed box which was real easy with info with the speakers. Pushing them with a Roc. Fost. power 500 by 1 dbcp and they hit pretty hard more than I though they would. BUY FROM THIS WEBSITE YOU CANT BEAT THE PRICE!!!
i just got 2 of these and have them on a punch 400 full gain full bass boost crossover at 85hz and you can hear me pounding 3 blocks away in my 2001 lincoln ls woofers facin forward with the backseats folded down. Rockford is simply high quality equip and well worth the money considering ive already "burnt" two kickers and one jl from too much continuous power on my p400.2
Good sub for the money. I got two on a 2400 watt amp wired to two ohms and i get yelled at everywhere i go cause its too loud. I would recommend this to anyone.
