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.

Need an amp for this sub? Check out this Crutchfield-approved single-sub and dual-sub bass package.

To drive this single subwoofer, we recommend a mono amplifier rated between 300 and 600 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Bought these for my sons car and they sound AWSOME! Glad we chose to buy from Crutchfield. I was told by a local audio store owner that the reason Crutchfield can sell these at such a good price is because they are reconditioned. I called Crutchfield and they (Skip) assured me that was not true because the buy in bulk and that is the reason for the good deal. AWSOME people to deal with. Very nice and answered all my question. Will buy from again.

Pros: AWSOME sound, great price

Cons: None

The Rockford Fosgate P2D4 12in subwoofer I purchased is an excellent subwoofer for the price point. The build quality is great,nice materials and looks nice. I matched this single 12 to a 425 watt @ 2 ohms rms amplifier and couldn't be more pleased. I have this sub in a ported enclosure tuned to 30 hz and the bass is thunderous for a single 12. You can't go wrong with Rockford Fosgate.

Pros: Nice build quality,and materials. Large surround for good excursion. Trim ring gives a nice finished off look. 400 watts rms means you don't have to have a thousand plus watt amplifier.

Cons: If I nit picked this sub I would say that I don't care for the rubber boot on the magnet. It's only for looks and probably holds in heat.

Great sub

I have this single sub wired at 2ohms, down firing in a 1.75 ported box in a 2011 f150 s.crew running off of a JL JX500.1D this sub slams hard and that's -300 watts of the 800 it could take. I bought this as a temporary sub, I blew my 12w3-4ohm since life is hard w/o bass I purchased this because it was so cheap. It hits way harder that the w3 I was pushing, as it should(ohms &wattage) when buying I thought if it's nice I'll stick w/ rockford. Within the 1st couple songs I noticed the accuracy & tone of bass is no where close to that of JL audio, now I see why they're products are in the bracket that they are. No discredit to rockford, this is an awesome sub.. I also may not be comparing apples to apples? But this is my experience. If you are building a system on a budget I would hands down recommend this product, with the right wattage these will shake your s**t down

Pros: My rear view is useless. A lot of ppl are surprised I'm only running 1 sub, back massage when I have it turned up, price point

Cons: Accuracy & clarity(after replacing JL sub) if this is your first sub or your not coming from something with very good clarity you'll never know the difference

I bought 2 for home theater use.Set in a 1.87cf labyrinth @37 hrz tuned box for each speaker..Powered by 2 old school QSC 1400 amps bridged at 600 watts/200+damping factor per speaker and use a active crossover with 12 db bass boost set to 40 hrz rolloff..10' 12 ga. pro wire per amp..Marantz 9.2 A/V head.

Pros: Hit hard and deep with above combo...Good control and accurate sounding above 200 watts. Nice milled dress ring for mounting.

Cons: Need a quality amp with plenty of reserve. A low quality amp wont make you happy with the results.. Not Pro grade but for the price its above average..id call it a good mid grade woofer.

I have this hooked up with a kicker amp pushing 200 watts and this thing can get loud. My system is pushing a total of 1100 watts of power total. My parents always know when I am coming home because they can hear me coming from a mile down the road! This sub is awesome and very loud but don't expect to rattle windows but it you will feel it in the car for sure. I have it in a ported box and there is nothing wrong with it, I have not had any issues with it at all, no over heating or nothing, Great Product, Well done Rockford, Well done.

Pros: Loud, Cool,

Cons: Nothing

Surround separated.

Bought this sub about a year ago and had it installed in a 1.0 cu. ft. sealed box pushed by a JL 500v2 amp. After the break-in the sub started to really shine, good bass but I always felt it could be better. Don't get me wrong it's a very good sub I just wanted something that would hit a little harder. I listen to rap, pop, metal, and classical and it did a very good job especially when playing metal. But! After about a year I noticed the bass wasn't as hard and it sounded like something rattling. Looking at it I noticed the rubber surround was starting to separate from the cone. It never got pushed very hard so that left me disappointed. Up until then other than wanting a little more bass, the sub was great. Could have just been a defect because I have had two other RF subs in the past and both worked great.

Pros: Tight bass

Cons: surround separated(could be defect)

I have to 12 "p2s in my car they are great subs the dual voice coil gives you lots of options for ohm load and different wireing i have them them set up 2 ohms with 1800 watt amp it sucks more then the amp can give.Ive destroyed a diamod amp and two of these in 2 years, but both we my fault. The first one i didnt know about duel voice coils and only hooked up one side. It worked great for a couple weeks but it made the sub work twice as hard which caused it to smoke and i melted the coil. the other got destroyed from poundng aginsts something in my trunk. After i hooked them up correctly and cleaned my truck they hit hard in cold or hot weather (in colorado we have both sometimes in the same day!) im a firm believe in rockford. had a few different subs over the years and rockford always delivers. increadble lows great high spend a few extra bucks and get these promise you wont be dissapointed

Pros: Sound looks relibility durability over all great sub

Cons: absolutly none as long as you hook up dvc correctly read the manuel with it for different ohm load wiring diagrams

This Subwoofer is one of the Loudest Subs ive bought so far. I had 2 15in P1's and one of these compare to them loud wise. The only thing i dont like about this subwoofer is how warm the coils get after about 30 mins of use. Ive never had a sub run this warm, its not like burning hot but you can feel its getting warm so sooner or later im gonna melt one of the coils. I have a Rockford Fosgate R750.1D Hooked to it running at 2 ohms which the amp is putting out about 500 watts, so it says but i think this amp pushes more then its rated. But still they need to build it better so they dont over heat. For the Money, its worth buying. Very Loud

Pros: Loudness, Clearness

Cons: Heating Issue

Awesome!

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).

3 questions already asked

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 ]
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. [ Kenny  Feb 12, 2016 ]  Staff
