Rockford Fosgate P2 Series Subwoofer

2 Punches and You're Out!!

When it comes to car subwoofers, Rockford Fosgate raised the bar in terms of high quality affordable subwoofers. These Punch Stage 2 subwoofers are the perfect combination of price and deep bass. The new Punch Stage 2 series will crank out 400 watts of RMS power handling, giving you that nice deep bass without over powering your audio system. The face of the woofer has been upgraded with a kevlar reinforced paper cone that will provide durability and great sound quality. For those long sessions of hard hitting bass, the rubber surround has been manufactured to handle high excursion movements through out the day. With their patented technology the Rockford Fosgate P2D4-12 are the perfect match for those looking for quality bass without breaking the bank.

While built on a long standing history of performance, the punch series woofers can deliver not only output to satisfy you when you want it loud but maintain a level of sound quality for when you really want to "listen" to your music. Taking many design cues from the Power Series, Rockford Fosgate engineers continue to improve the Punch Series year after year making it one of the most sought after woofer lines for music and bass enthusiasts alike. With features like Dual tear & fatigue resistant poly-cotton spider for high strength and anodized aluminum voice coil formers to handle heat buildup in the motor structure under full power situations, these drivers are designed to perform.

 
Anodized Aluminum Voice Coil Former

Anodized Aluminum Voice Coil Former

By using an anodized aluminum voice coil former on their subwoofers, Rockford Fosgate is able to dissipate heat from the voice coil more efficiently. A hot voice coil can melt the adhesive bonds, which will lead to eventual subwoofer failure. The aluminum voice coil former acts as a heat-sink to dissipate thermal build-up on the voice coil cool during high SPL conditions.

 
CEA-2031 Rockford Fosgate Subwoofers

Conforms to CEA-2031

Rockford Fosgate has built this subwoofer to conform to the CEA-2031 loudspeaker power handling industry standards. This means that you can trust the subwoofer to have the capacity to safely handle the continuous (RMS) power rating. Having a CEA-2031 power handling is important when matching a subwoofer to an amplifier because the power ratings are accurate.

 
Rockford Fosgate Stitched Tinsel Leads

Stitched Tinsel Leads

To improve the reliability and performance by reducing fatigue and possible shorting, Rockford Fosgate has stitched the tinsel leads to the spider. The multipoint periodic stitching lead wires reduce the mass of the tinsel leads to spread the stress over a greater area. This improves the reliability and performance of the subwoofer.

 
Rockford Fosgate VAST Surround

VAST: Vertical Attach Surround Technique

In order to increase the surface area of the cone without causing any installation issues, Rockford Fosgate designed the Vertical Attach Surround Technique (VAST). By redesigning the manner in which the surround adheres to the basket, these speakers gain up to 25% more effective radiating cone area. This improves the nominal efficiency and maximum output.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Punch P2 (Rockford Fosgate)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
12"
Peak Power Handling
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.
800 watts
RMS Power Handling
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
400 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Dual
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
2.25"
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
27.2 - 250 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
86 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
13.3 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Black
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Kevlar Reinforced Pulp (Paper)
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Rubber
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
No
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.7 cubic feet
Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.8 cubic feet
Minimum Ported Box Volume
This value indicates the minimum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.79 cubic feet
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Ported Box Volume
This value indicates the maximum ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
1.79 cubic feet
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
6-1/2"
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
11-1/4"
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
27.2 Hz
Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
81.5 liters
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
0.54
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 – 10.
0.59
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
6.40 ohms
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 – 10.
6.30
Efficiency Bandwidth Product (EBP)
This number represents the trade off between having an efficient woofer and one with a wide bandwidth. To calculate this number, take the Fs and divide it by the Qes. If the number is below 50, the woofer is designed for a sealed enclosure only. If it's between 50-100 it can be used in either. Lastly, if it's greater than 100 it's designed for vented enclosures.

Amazing "punch" for your buck!

February 15, 2012

I put 2 of these in my friends buick, and let me tell you, just getting through the break in period, they hit hard, and we were watching them in his trunk and they are barely moving! These things are going to be champ status! Great sound quality, Great price, what more do you need?

Incredible Sound!

June 28, 2012

I have a pair of the p2d4-12s where my backseat used to sit. Not that I need that much space because they only require 1cu ft of air. But I have them in custom ported enclosures which are consideribly larger. But with just these powered by a Punch T600 you can literally see the air pushing the quarter panels on my car. Stick your head next to the window and you can feel your hair moving. My car is all black so the smooth clean black look with the machined trim ring was a perfect compliment to the "blacked out" look I was trying to keep. They are so much better than the old school 15s I had back in the day which took up so much mor space! I recommend these to anyone looking to upgrade to a great sounding system but doesn't want to lose every inch of you trunk space...

great sub

June 14, 2012

This sub hits really good and looks great. I have been running it hard non-stop from day one. It sounds powerful, tight and clean. I have also pushed 500W RMS for awhile with no problems, this sub is tough. My only concern is why the basket is designed with plastic (or thin metal). A little cheap, but I don't see any issues arising from it.

November 24, 2013

I have this sub in my mustang. And WOW. Does this thing hit. I love this sub and never want to get rid of it! This sub is almost to the point of its too loud. I told my friend I was ordering this sub and he told me to get two. glad I didnt. theres no need for anything else for bass. I have it in a belva ported enclosure with a rockford fosgate 500 amp and I am more than happy with my purchase. way more powerful than I thought it would be! buy this product!!!!

February 23, 2015

I have two of these in a ~4.5cu ft box tuned to 30hz. Slams so hard and gets low with ease. Blows away my sealed Fi Q on 2000W. Couldn't recommend these subs more. Huge Rockford fan and have always been happy with their products.

Decent sub

July 9, 2014

I bought this woofer to put in my boat and as soon as I got it I put it in a ported box I had from a previous woofer and plugged it into the zx750.1 I have powering my JL w3v3 13.5. The sub didn't hit quite as hard as the w3 which I expected. It also seemed to really struggle on some of the higher frequency bass notes that sounded clean on the w3 which suprised me because of the smaller size. I'm wondering if the box I have is a little too big for this woofer because overall I was pretty bummed with its performance, especially because I have heard plenty of good sounding Rockford woofers before. Listen to it before you buy it and make sure whatever box you are putting it in compares to the box you are listening to it in.

big bang for the bucks

December 19, 2013

I ordered a single Rockford P2D4 12 inch to add some punch in the existing stock Bose system for my daughters mazda 3 hatch. And i cannot be more then thrilled i made the best purchase for the price. I know its the 2nd generation P series but this sub hits hard. Its connected in parallel from 4ohm to 2ohm load so i can get 480rms power from old school Punch800 a2. I can bridge amp to 800 rms but really don't have to. This set up shakes the inside of the vehicle. This sub can take more abuse. I highly recommend it.

powerfull and affordable!

September 21, 2011

as with any properly made speaker these speaker have the potential to destroy the silence. If your wire them correctly and understand how the load is distributed you will love these speakers (go to their website and view diagrams). I would not recommend these speakers to you if you bought your amp at a flea market as they will suck the power out and fry your board. Remember big speakers need lots of constant power to perform as needed so don't cheap out on your wires and amps.

In a dual box in the back of my 02 trans am and the flex I get from these are amazing. If you know what you're doing, thes subs will be a great addition to your system and will not overheat your amp. Very impressed.

Big improvement over the RE Audio sub it replaced

March 17, 2013

I took a gamble on the RE Audio SRX 12 with dual 4 voice coils after reading tons of great reviews on them. I was unimpressed as it just didn't sound as musical as previous Fosgate subs, even cheaper ones. Also, the stitched tinsel leads broke loose and it wasn't even a month old. Sonic let me return it and upgrade to the Punch P2D4. Very glad I did, this sub hits way harder and sound far more musical than the RE. Its well worth the extra cash. I've been driving it hard with 300 watts no problems at all, even with the bass boost set at 40hz and cranked high.
If you've owned Fosgate products before and are considering saving a few bucks to go with a budget brand, save yourself the trouble and get the real deal.

great subs

June 18, 2012

I currently have three of these subs in my car. I run 2 of them off of kicker 1000.1 dx amp and 1 off of the kenwood 9105d amp. Kicker amp puts out 1000 watts rms and the kenwood at 2 ohms is 900. I love these subs I still have one of the older generation p2's with the plastic cone which is broken and it still bumps. The two newer generation subs definitely look better and im sure the cone holds up better then the older one. Im currently saving up to buy 2 p3's to replace the busted p2. Make sure you buy a good amp to power these subs. The kenwood amp is the 3rd amp i had with the p2's and the kicker amp is the 4th. These subs sucked the life outta the cheaper amps. I recommend the grill with these subs because they bump so hard if anything touches the cone it's either gonna tear up the cone of what ever is touching it from experience. Oh and last with a good amp its gonna suck alot of power so make sure to get a cap. I have 50 farad cap and with the 3 amps my lights still dim a little bit.

Great sub! When powered and tuned correctly, this sub hits every tone you could hope for a sub to hit. responds well to rock, but also hits hard for those bass lovers. Demolishes all my competition, which always consists of multiple twelves and fifteens. This is a great sub for anyone looking for good clean bass across the spectrum, and its fosgate, its gonna last. A+

Good subs great value

December 4, 2011

I put two of these subs in a dual bandpass box powered by 1800 wat kenwood and man do they hit hard but i do recomend at least 4 guage power wire with a good battery. If you have a small car with a small battery you should invest in a capasitor these use alot of power and can overwork your alternator and drain batteries and dont go buy your amp at walmart they need real power for the optimum sound experience.

Lives up to its name

May 30, 2012

These subwoofers most definitely live up to their name. I have these running on a CRUNCH PZA 1400.2 in a SEALED, that's right, SEALED box and they slams harder than my dads ported setup with two 12's that are just as powerful. Shaking garage doors and knocking cans off shelves in my pantry! These subs are most def worth it and they EASILY live up to their name! You feel the bass in your chest!
