About the Rockford Fosgate P2D4-12

Standout performance

Rockford Fosgate showcases their fanatical commitment to sonic excellence in the Punch Series of speakers, amps, and subs. If you like to listen to potent, powerful music — and feel it too — Punch components will give you impressive sound that'll stand out in a crowd.

Cutaway view

Bulletproof bass

Engineers at Rockford Fosgate designed the P2D4-12 12" subwoofer to dish out the kind of powerful low end you crave in your ride. Its responsive paper cone is reinforced with the same Kevlar® fibers used in bulletproof vests so you get the best of both worlds — warm bass that's exceptionally hard-hitting. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass.

Made for heavy excursion

This P2 sub features an extended pole piece and bumped backplate that leaves more room for heavy excursion, so it'll hit deeper lows without "bottoming out." Special venting keeps the copper-clad aluminum voice coils cool through heavy use for consistent bass performance over time.

The dual 4-ohm voice coils allow you to wire the sub for 2-ohm impedance to work with a mono sub amp, or for 8-ohm impedance if you're using multiple subs. The P2D4-12 sub works equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.

Features

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.

Enclosure Compatibility

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).

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system.

Q
Is this subwoofer a free air subwoofer?
[ Brian  Jul 01, 2017 ]
1 answer
A
This is NOT a free air sub. The box I got came with the sub from Sound Ordinance and is roughly 1.5"L x 1.3"W x 1.3"H almost a cube, I highly recommend this sub however especially given the price. Couldn't be happier.

Q
OE compatible?
[ John  May 02, 2017 ]

I don't think a factory amp would be able to power this subwoofer and even less likely of a chance that it will fit a factory subwoofer location on a vehicle. However, we may have some that will work. I recommend contacting an advisor on 1-800-324-9695 for a recommendation on a replacement subwoofer.

Q
Can I put this subject in a sealed box that has .9 cu in the box?
[ Jalen  Oct 03, 2016 ]
1 answer
A
I had that sub in a 1.25 sealed box and it sounded great until I fried the sub. I had my gain set too high and the sub got too hot and my coil burnt up. I then went to a 1.6 ported box because the port helps cool down the coil and magnet. The amp used was a RF Prime 500X1D. But anyway the sub was very powerful in the 1.25 sealed box I imagine .9 would sound good too but I would suggest go bigger.

Can I put these subwoofers in a sealed box with the cu ft 0.9?
[ Jalen  Sep 07, 2016 ]

I havent been able to install mine yet. But im an advocate of ported boxes in my oppinion their better but the manual for the sealed is 1.02 cu.ft.
[ Alex  Sep 14, 2016 ]

I bought a ported box for my Rockford and it sounds a lot louder than a sealed box.
[ Bill  Sep 09, 2016 ]
Q
I'm going to buy the RF DVC 4 OHM. Im Going to power it with the Alpine PDX-V9. The Sub will be getting 500 Watt's RMS, Will Someone let me know if 500 Watt's RMS is enough?. In my own opopinion it should be a very good match Please Reply and let me know if I'm looking at this correct? "Thanks Much..
[ Craig  Aug 05, 2016 ]
1 answer
A
Yes as long as you are just running one sub to this amp that should be a good match since the sub is only rated at 400 RMS. This is always under rated though. I've got 2 pushed by a RF 1200 rms amp and the subs handle it fine. So to answer ur question yes that should be a good combo.
[ Spencer  Aug 05, 2016 ]
Q
Can I use a Pioneer GM-A5602 2-Channel Bridgeable Amplifier with 900 Watts Max Power and Bass Boost Control for a pair of Rockford Fosgate P2D4-12 Punch P2 12" subwoofer with dual 4-ohm voice coils without blowing a sub or frying my amp?
